    I'm wondering how many Pinsiders have amassed a collection of vintage stereo equipment. This thread is dedicated to the audio equipment (including speakers) of yesteryear. . .the good, the bad and the ugly. Post photos of your set-up(s).

    This thread is more about the equipment itself as opposed to musical preferences. To post photos of album covers, for example, there's a great thread on Pinside for that (Pinside Vinyl Club).

    I'll get this party started with photos of my gameroom set-up (as listed below), followed by a photo of the Sansui stereo (long gone) I had in my college dorm room back in the late seventies.

    Setton RS-660 receiver (120 WPC)
    Marantz 6350Q turntable
    Marantz 4300 quad receiver (100 WPC)
    Tandberg TCD 330 cassette deck
    Kyocera DA-610 compact disc players
    Panasonic quad audio scope SH-3433

    Pioneer SX oldschool receivers was my jam back in the day. The polished stainless steel fronts and bouncing power meters was the shit. You can feel the power.

    The Pioneer SX-1980 is indeed a monster at 270 watts per channel. Here's a link to an article listing the most powerful vintage receivers:

    Here's the Setton RS-440 receiver I use in a bedroom. It's rated at 70 watts per channel (the Setton RS-660 advertised at 100 WPC but rated at 120 WPC, released in 1977, is pictured in my first post). Setton isn't that well known outside of the audiophile world. Setton equipment had a short run in the late seventies. Their receivers were manufactured in Japan by the same outfit which made Lafayette Radio products, although some claim that they were made by the parent company of Kenwood. Most evidence points to Lafayette insofar as the internals are very similar, although not identical.

    Setton products were styled by an acolyte of Pierre Cardin, Allain Caire. A French distributor of Pioneer, Jack Setton, is the namesake of the brand. The unconventional controls include a unique security panel display, which display "heat," "clipping" and "protection." The sonic performance of Setton receivers (there's also an RS-220 which features 40 WPC) is impressive.

    I just love the old receivers with the knobs instead of the new crap with a remote that's needed to adjust all the settings and if ya loose the remote your up shit creek. The old ones were great to look at too, real works of art. I'll have to look for mine.

    I have the Pioneer SX-1250. It's a freakin tank, takes two people to move it. Although it's power full, it isn't the best sounding one I have. My two rebuilt Marantz receivers (2230, 2270) sounds soooooooooo warm and inviting. Playing vinyl on a Technics 1650 (best changer ever made) though the 2270 over a pair of HPM 150s is magic.

    #7 7 years ago

    I grew up on the end of cassettes (early 2000's), and recently went back to them (purchasing ones that cater to my up-to-date music taste though of course, no kids music like back then) and "use" a select few daily in my car for real legitimate listening. They sound amazing - much better than all that compression using phone adapters and whatnot. I love them. I've probably gone through three of my favorite usual tapes a hundred times now on car rides, long or short. Very loud...

    I've been looking for a good turntable for the pinball basement for a while now to no avail. Used to be able to find okay cheap old stuff at thrift stores, those days seem to be long gone now. Now it's either expensive new stuff or expensive old stuff. I just want a $30 beater, no need for audiophile stuff for my basement. If I can make the room, might just get a jukebox. I have my grandparent's amazing complete stereo upstairs wired into the basement and if I want to hook it up eventually I have a really high-end movie theater receiver from the late 90's I got off of Craigslist for $20 two years or so ago.

    The knobs on many of these vintage receivers are silky smooth. The buttons on Settons are solid metal with nylon inserts. I also like the controls on Marantz, Sansui, Pioneer, Rotel, Scott, Concept and many others.

    Pinball and vintage stereos go hand-in-hand, in my view. They share the visual, audio and tactile elements which draw us in and transport us to an earlier time. My line-up is mostly electromechanical pinball and arcade games. I blast music on my vintage system while playing pinball. The music complements the chimes, bells and buzzers of the old-school games.

    Please post photos of your set-up. Hopefully, others will be encouraged to do so and we'll create a unique thread.

    I don't use the seperate amp, receiver, cassette deck or the eq anymore, they're in storage. The speakers are JBL 4311B Studio Monitors

When you have 9+ receivers and enough sound processing equipment various reverbs,equalizers etc for a new one each day of the week and too many speakers it breaks i just shelve it.

    Current gear in the junkyard is follows

    Sansui Qrx-3000
    Sansui Qr-6500
    Dennon Avr-2500

    The new stuff they make is amazing. Just buy one of those tables for $150 and you will be good to go with what you want to do with it.

    I still have a love/hate relationship with tapes. They can sound amazing, but they degrade and can also sound like shite for no reason.

    #13 7 years ago

    I have a Marantz 2245 and a Pioneer SX850. Those are connected to Polk Monitor 10 speakers that I rebuilt. Great sound for the gameroom.

    I rebuilt my Cerwin Vega D-9s last year. I'm looking for a monster receiver, mine is only 120 wpc. That will drive them up pretty good. Still have my lps and a Sherwood linear turntable.

    I have a Yamaha CR-820 and some Boston A150 speakers I was trying to sell, if anyone is interested. The speakers need resealed. The receiver is beautiful. lights work. There is a small probably cigarette burn on the top, probably 1/4" dia spot. I have the box and the manual for the receiver. Unfortunately I accidently threw out the styrophone packing. I'd like $250.00 for all. If interested, shoot me a PM for more information. I would prefer not to ship. I would donate to pinside if I sold through here.

    This thread might be a good place to post "for sale" notices of vintage stereo equipment while generating donations to Pinside.

    Marantz receivers seem to have earned the reputation for a distinctively warm sound, which is a proposition supported by my experience with my Marantz 4300 quad receiver (with SQA-2 decoder).

    But are you old enough to remember having an under dash record player in your car. My older brother had one in his '65 Mustang. I thought was sooooo cool at the time.

    #22 7 years ago

    My other hobby not related to pinball is the restoration/repair of vintage audio equipment. In my present collection, I have restored/repaired:

    Yamaha C-80 Preamplifier
    Yamaha M-80 Amplifier
    Magnepan MG-I speakers (these were fun to rebuild, tedious but fun. These sound absolutely amazing!)
    Carver TFM-15 Amplifier
    Carver PM-900 Amplifier (just finished)

    Looking for other equipment now as I've run out of projects. Typically look over eBay and a few other Audophile sites for classifieds.

    I am a late convert. They offer a nice punch of power in a small package and do sound wonderfull when they are recapped.

    Quoted from MustangPaul:

    My older brother's first car was a red '67 Mustang. Mine was a '72 Mustang convertible with a 302 Cobrajet engine (canary yellow with black ragtop. . .I had the car repainted pearl white and replaced the black top with a beige one). While I do not remember the underdash record players in any of the family cars, I am familiar with those ingenious audio devices. Here's a concise history, with photo:

    #25 7 years ago

    Ummm, was not born yet. In the late fifties, Chrysler had optional record player. Ford sold a Rotunda or a Philco unit to be added at the dealership. Vintage cars usually had just 1 speaker. The Ford unit did not fair well on bumpy roads. Hot cars in the summer were also poor storage areas for vinyl records. Please correct me if I have the facts wrong, as none of my family had record players in their cars.

    8 Tracks had 4 channels. 1 thru 4. Cassettes like records have sides.

    I have my parents Sony TC-255 reel to reel in pieces right now. The parts are in. I just haven't picked them up yet.

    My Mom's Dad was a preacher and used to record church services with this player to be played on the radio. I'm excited to hear them and convert them to digital.

    Quoted from mswhat:

    There's a local flea market that has one of these and it sounds so good. It's a consignment and the store owner said the owners decided against selling it. He played it for me though. I should make an offer.

    Some of the monster receivers seem to be outperformed by their less powerful brethren. For example, the monster Marantz 2385 (185 WPC) is eclipsed in performance by the classic Marantz 2285b (85 WPC). I think that the same may be true of other brands.

    I might go pick up an RCA dual cassette recorder this weekend. I've got a few cassettes but no player right now.

    If you're looking for a record player you might have to modify your search.

    Consoles are usually pretty cheap because they take up so much space. But if you like the look of wood grain (like I do) they usually sound pretty good and provide some good storage.

    Portable players also work really well. A couple weeks ago Dad pulled a Symphonic portable unit out of the closet. It was one like he had as a kid. He got it a long time ago but never played it. They look like a briefcase with a handle and lid.

    He cleaned the case up with some bleach cleaner put an old flapper record we had never heard before and it started right up. It sounded great for such a little thing.

    Quoted from Darcy:

    8 Tracks had 4 channels. 1 thru 4. Cassettes like records have sides.
    Now where are the reel to reel units?

    Ah yes. I just remember pressing a button to change channels and that songs were, at times, broken up between consecutive channels.

    In retrospect, the 8 track seems primitive. Yet, I have several EM arcade games which use reliable 8 track tape systems for the audio component, e.g. 1972 Sega Grand National Race, 1974 Kasco Untouchable. My 1973 Sega Moto Champ's 8 track system was converted to a solid state equivalent. Of course, these 8 track tapes run in a continuous loop in lieu of channels.

    Most of my youth was during the cassette phase. The Tandberg TCD 330 cassette player (shown in post #1 above) does a nice job making many of my old cassettes sound more like compact discs in clarity.

    Do you think it's a question of pairing it with the right speakers? Does volume have anything to do with it? I imagine more powerful receivers would work better when pushed harder.

    #33 7 years ago

    My stuff isnt that old but its some nice high end late 80s equipment.

    Adcom series one GTP 350 preamp tuner
    Adcom series one GFA 545 amp
    Rotel RDV 1060
    Dalquist DQ12s

    Stuff still plays as good as the first day I bought it.

    I cannot attest to the superiority of the Marantz 2285b over the more powerful 2385 from personal experience, having never owned either. However, I have participated in audio forums for a few years and this is the consensus among those who have owned both units.

    Also, the 2285b is revered by the audio review magazine editors and other audio gurus, both then and now. Thus, I'm never surprised to read about the 2285b topping the list of just about any vintage seventies receiver in a head-to-head comparison.

    Indeed, I would like to add a 2285b to my stereo line-up, at some point.

    The thickness of the tape in 8 track was its best feature. Hardy tape compared to the cassette.

    I know that Pinsider John Robertson of John's Jukes in Canada is able to duplicate some of these old arcade game 8 track tapes. I have purchased a few from him. He's able to successfully splice the tape precisely because the tape has girth. However, he's described the treading process as utterly maddening, when the tape unravels.

    I was recently given a pair of Magnepan MG1's. The Magneplanar series began life in roughly 1976 (give or take). This revolutionary design used a mylar sheet with the voice coils attached to it, backed by many individual bar magnets. If you don't know about them, here's a good link that provide some basic info - https://en.wikipedia.org/wiki/Magnepan

    I remember these from my college days and was always fascinated by the nature of how the sound was produced. The gentleman that gave these to me said that they were given to him but he didn't even know if they worked. He gave them to me because I immediately knew what they were (upon seeing them in his sign shop) and that I knew how to repair them if needed. They are now in my shop after being restored. Some pics follow:

    3rd is the crossover (pretty simple)
    2nd pic is showing both the mid/bass coil (on the left) and the tweeter coil (on the right). Take note of the crusty stuff around the loop ends. That is corrosion on the aluminum wires used for the coils.
    1st pic shows more corrosion damage

    #38 7 years ago

    The red stuff you see coating the wires is a 3M product Magnepan used back in the day to help prevent corrosion. Obviously, after 40 years the coating has failed in placed. After checking these I discovered that both speakers did not work at all (either set of coils). A thorough visual inspection revealed numerous breaks and missing sections of wire. Since this wire is aluminum there is no real way to make a mid-span splice/repair. The only way to restore these speakers is to remove the old coils and replace them. This requires using Acetone to breakdown/remove the old 3M product. The difficult part is the fact these wires are bonded to a mylar sheet and great care must be taken to prevent punching holes in it thus complicating the repair/restoration.

    1st pic shows the speaker panel ready for restoration
    2nd, 3rd & 4th pic shows using an acid brush to apply the Acetone (sometimes lifting the wire and getting under it)
    1st pic you can actually see some of the tweeter broken in many spots

    It takes a while but you finally get all of the 3M product off and you can see the mylar underneath. In fact, in the first pic you can see the clear mylar and the bar magnets (left of the acid brush). Unfortunately, after removing all of the wires and 3M junk, I did find some holes in the mylar. These can be repaired by using mylar tape (Scotch brand by 3M) and some spray adhesive as the glue on the tape is not strong enough to stay bonded to the surface during the vibrations of the music.

    I had previously finished restringing both voice coils on the first speaker. the coils are held in place using 3M Super 77 adhesive. I started with the tweeter coil (32 gauge aluminum wire) and sprayed a coating of the Super 77 in the tweeter section. Once the Super 77 becomes tacky (knuckle test - adhesive doesn't stick to knuckle), I started laying down the tweeter wire being careful to keep the wire centered between the magnets. I left approximately 1 ft of wire on both ends so that I would have plenty of "slack" to work with.

    2nd pic shows the use of an old fuse to assist in making the 180 degree turns to start another run

    Next, is running the mid/bass wire (22 gauge coated aluminum wire). Basically the same procedure as for setting the tweeter wire; spray some Super 77 down, wait for tackiness and begin placing the wire. This one however is a bit trickier as the wires have to lay side-by-side during the long runs but must lay on top of one another on the loops. Also, care must be given when forming the 180 degree turn to keep the end from curling up and away from the mylar. I found that by twisting the wire (toward the mylar) as I made the turn kept the wire flatter. Once the first run is completed, you need to bring the end back around to the beginning and do it again.

    Once the new runs have been allowed to set in the adhesive, you need to apply the 3M NF30 (Milloxane) sealant. Although the can sent by Magnepan had a small brush applicator included I decided to use a 1" foam brush for applying the sealant. I applied two light coats, waiting 12 hours between each one. Light coats is the key here as you want the mylar to remain flexible.

    While these were drying I decided to work on the crossover network. I had ordered some replacement capacitors as I assumed the existing ones would be dried out after 40 years and the values changed. Just for grins, after removing the caps, I tested them on my little component tester. Yep, confirmed; both capacitors were definitely way out of spec. They were supposed to be 12mfd and tested out as roughly 38mfd; definitely changing the bandwidth of the circuit.

    I also decided to replace the "connection block" (nothing more than some connector rings riveted to the mounting plate) with something a bit more forgiving to work with. The old connections were made using silver solder due to the dissimilar metals being used (copper wires, copper connectors and aluminum wires). Although I was trained in the Navy on how to solder to aluminum with silver solder, the process is not easy and I'm far out of practice. All pieces to be soldered need to be scrupulously clean and heated to the right temperature. I made one attempt and decided on a better method. I substituted a standard screw terminal connection block. All wires/component wires were sanded clean, dipped in No-Ox-ID (to prevent oxidation/corrosion) and then placed into the block.

    Fascinating series of posts, Half_Life.

    I'm in my bedroom on Pinside, listening to an album, so I figured that I would post a photo of the workhorse Dual 1229Q turntable I've had for several decades. Dual's turntables were highly regarded in their time. Their simple and elegant engineering has stood the test of time, in my view.

    Incidentally, I use Novus 1 with my Discwasher to clean my albums and stylus. I'm wondering if others do the same.

    Here is a list of equipment I bought in Dec 1979. That I still occasionally use.
    Dual CS606, with a Ortofon ULM cartridge.
    Sherwood Receiver S-7250.
    Sound Shaper Two, Mark II equalizer.
    TEAC A-103 Cassettte, recording feature stopped working.

    Have upgraded everything except the turntable.

    Quoted from ZNET:

    Some of the monster receivers seem to be outperformed by their less powerful brethren. For example, the monster Marantz 2385 (185 WPC) is eclipsed in performance by the classic Marantz 2285b (85 WPC). I think that the same may be true of other brands.

    I was tempted to pick up one of the 23xx ones, to get some more power. However, after awhile I realized I didn't need any power and the 22xx models were fine enough. Even my 2230 can crank it pretty good.

    I've always been tempted to try tubes...

    I mostly use tubes on the digital media. I think it warms up the music to a vinyl/analog sound. The Mc Intosh is solid state and I run the Thorens turntable into it. The Macs and records are warm enough, imho.

    I have two Marantz rigs with one being the monster 4400. Pics tomorrow. Cool post!
