Quoted from Thunfisch:

As you can see, Alltek uses SMD parts, but supplies you with holes so you can repair it with old-fashioned parts. You can use the original type that was on the original Stern board. By the way, it's not a transistor but a SCR (silicone controlled rectifier, or "Thyristor")

Thank you. I was looking right past the repair holes.

The thing of it is I just got finished building one of those Pinitech UNO displays kits. Each display board has one of the surface mount units to install. They were a snap to install with just a solder iron. So, if Alltek would send me some of these surface mount SCRs I would apply the heat and R & R it.

Quoted from Thunfisch:

I guess it is this one
https://www.marcospecialties.com/pinball-parts/2N5064
Can somebody else please confirm?
I guess 2N5060 might do the job as well?

I'll call Alltek in the morning and confirm what we should be using.

#5352 12 days ago

Ha ha, it's printed right there on the board. 2N5060 I think. I did this a long time ago on a Harlem Globetrotters and it worked just fine.

Anyone need a f2k big drop bank? Not mine. Some dude on facebook has one.

You are right. I repaired mine with a 2N5064 SCN and it worked as well. (See photo some posts above)

Thanks for sharing this info. I could replace as I have those part numbers in my inventory. But my board has trace damage, as well. I'm guessing the traces will still work but I am going to try for a replacement board.

Alltek has sent me an email this morning with a return authorization so I am sending it in and will ask for a replacement board.

Quoted from cottonm4:

The linked post is where I talk about how I fixed a set of bricking drop targets. This thread is where I talk about the drop targets falling down prematurely.
The 3 drops in this left hand drop target would not stay up when lifted. One of them, and it could be any of the 3, would always fall down when they were raised back up.
The cause of the problem was that the drops would be pushed up and they would be pushing against the play field and this play field contact would make them fall prematurely. There is no room to push this drop assembly back farther in its slotted hole so I had to get out my rasp and some 80 grit sandpaper and keep sanding the play field away in this slotted hole. I have frontal clearance with the drops and one of them is still making contact, but getting some empty space in front of the drops and adding new return springs stopped the falling down.
[quoted image]

So, my experience suggests if your drops are bricking, you need to make sure the drop is not slamming into the rubber ring and you may have to move the drop assembly forward a couple of millimeters. This means you have to fill the holes your drop assembly screws into and move the holes forward just that little bit.
And if your targets keep dropping down then you probably need to make some clearance between the drops and the play field slotted hole.

I had the same issue on my Meteor where the slot for one of the 3 drops was too small for the new style drop targets to work properly. In my conversations with CPR they said they would expand the cut out in future runs. Maybe someone should reach out for Star Gazer too.

Does this mean CPR is the one that took over the Greatwich stuff or was CPR planning to do Star Gazer anyway?

#5359 11 days ago

CPR are acknowledged to not the buyer of John’s setup. No offense to bigguybbr (follow his Trident resto thread!) but I wouldn’t take any weight on his comment. That said, I don’t have any inside knowledge of CPR’s plans.

#5360 11 days ago
Quoted from Clytor:

He’s just saying maybe reach out to the guy making Star Gazer (John). On a side note, CPR said 2-3 years ago in one of their bulletins that they will make Star Gazer, Seawitch and Nine Ball playfields.

Quoted from Clytor:

Sorry didn’t know Stargazer wasn’t a CPR title or anything about it really.

I was just sharing my experiences with drop targets, and that CPR had said they would change their CAD file for future runs for Meteor, and to maybe reach out to whoever is producing the playfield and see if they can change theirs in the future.

The statement holds true about the slot being too small however. It causes a bunch of problems with the larger top targets.

Would any of you expect the following voltage differences on a new power supply board to cause the mpu not to boot?

TP1 Actual 6.3vdc Spec 5.4vdc
TP2 Actual 256vdc Spec 230vdc
TP3 Actual 15.5vdc Spec 11.9vdc
TP4 Actual 6.93vac Spec 7.3vac

No.
Those voltages are in range.

I just traded emails with Kerry at Mantis Pinball about reproducing some new sling shot arms for the classic Sterns. He was trying to get them to where he could sell them for $15.00 each. And he cannot make them at that price.

It is an example of something that can be made, but not at a price anyone would want to pay.

Maybe someone can ask Terry at Pinball Life if he wants to look into possibly making these.

I need new slingshot mechanisms for my Flight 2000. I would buy 3.

Did he try at $25.00 a piece ?

#5368 5 days ago
Quoted from cottonm4:

A pair of Stern sling shot mechs sold for $55.00 recently (incl US shipping) on ebay. So essentially $27.50 each for a worn sling shot arm.

$25.00 each as Vec-tor suggested would seem a reasonable price to pay especially as buying a used one will most likely be worn crap & expensive.

#5369 5 days ago

Not having the slings egged out makes a HUGE difference in the slings. I was lucky enough to get 8-9 NOS ones years ago and used them on my flight 2k and it was night and day.

When I ran with this quite a while back, everyone was saying $15.00 each was the most they would pay. And now $25.00 each is not a problem?

So................how many of you are going to step and lay down $50.00 for a pair of sling kickers? If just 5 or 10 of you pop up and say " I would pay that much" I wouldn't insult Kerry by asking.

Stand up and make your self counted.

I'd buy a pair at $50.00/pair. Maybe two pair.

Count up.

#5371 5 days ago

I need at least 4 if I want to get rid of the slop in my Trident, 6 if I want spares to swap out my Meteor if it makes that big of a difference. $25 a pop isn’t too steep if they are well made. My Mantis lockdown bar was fantastic, so I would expect similar.

#5372 5 days ago

I would buy 3 of them.

#5374 5 days ago

I’d pickup up at least one pair.

Is Kerry capable of producing a pivot bracket (A-143) to accompany these?

Thank you for your efforts, Cotton, to move this forward.

On top of my pair, you are either going for 6 or 8.

#5377 5 days ago

Any of the Classic Stern folks bringing any games to Pinfest? I will have a Stars there to play.

That's makes you 9 or 11 depending.

I'm down for a set.

This makes you set #12 for a pair.

Next guy up, count your self in so I don't have to keep looking back to keep track.

Thanks.

Kerry does not need to repro the bracket.

a-17810 kicker bracket (resized).jpg

Just installing one of these will get rid of a lot of your sloppy action. It is not an exact copy. You have to file out the side of one holes to allow clearance for the kicker arm. You should also fill one hole in the play field with some dowel and drill one new hole.

You will also have to file away about 1/16" of the pivot cylinder as this unit has a little bit shorter pivot. It is EZ to mod this part and your kicker so it all works.

Thanks for your kind words. It is appreciated.

Number 15 is the last set I have. And you are.....# ??

#5383 5 days ago

I'm #17 for one pair.

#5384 5 days ago

I could use two to three sets.
I have a few that have snapped and are missing the head.

#5385 5 days ago

Shit, FOMO, what am I agreeing to purchase two sets of?

#5386 5 days ago
Quoted from Atari_Daze:

Slingshot kicker arms at $25 each, or $50 for a set.

#5387 5 days ago

Kerry said $25.00 has moved the needle enough that will try to kick out a couple of prototypes for me to a look at.

Sling shot kicker arms is what we are talking.

#5388 5 days ago

Are these arms universal between earlier games like Stars and later such as Seawitch and Nine Ball?

Quoted from frunch:

I hope so, they should be compatible with CDI Chicago Coin.

#5390 5 days ago

I’m familiar with this substitute because you shared it in this thread a few years ago. Thanks again!

It’s not that I’m opposed to solutions like yours, but I have sling mechs with substitute arms and brackets that I’m trying to bring back to original, as well as a dwindling supply of NOS sling arms that would pair nicely with repro pivot brackets.

I’ve never spoken to Kerry, so I’m not familiar with his capabilities, which is why I asked if he could reproduce the bracket; I am aware of his reputation for quality parts. Whether he’s interested in being the go-to vendor for repro SEI sling shot mechs, and whether it’s economically feasible to do so, are logical follow up questions.

Bringing back any of these parts, that have not been available for a long time, will help all of us get our games closer to how they were designed and keep them there. Thanks to all who have stepped up and raised their hands. Hobbyists like you, Cotton, that push these conversations forward, and manufacturers like Mantis, that cater to our common interests, are what make this community special.

#5391 5 days ago

I would buy a pair as well. Would be good to get repro brackets as well - in an ideal world.

Is the arm the main part that badly wears? or is it both the arm & bracket? I don't have a Classic Stern ATM to determine.

#5392 5 days ago

Looking at my Flight 2000 tonight, I realize I need 4 of these, not 3. So I need 2 pairs or 2.

#5393 4 days ago

I believe these arms are prone to breaking at the top as well as wearing out - so their may be quite a few people in need of them.

#5394 4 days ago

I’d buy 4 sets at least.

#5395 4 days ago
Quoted from Tsskinne:

No need to keep counting. Kerry has been having good fortunes in selling his parts. For the $25.00 price he thinks he can risk some time trying to make them.

When I first proposed this to Kerry, I sent him one of my most worn kicker assemblies along with the pivot bracket. I advised him of the pivot bracket that is already out there. I did not push for him to make the pivots.

I understand your desire for remaining in original condition. I figure if he can make the kicker arms and start selling them, perhaps he might be willing to make the pivot bracket. But the kicker arms are first priority. No kicker arms and you don't need the pivot bracket.

In the meantime time, if you make your goal of remaining all original you can make that happen. Take your old worn pivots to a local machine shop that could remove the worn pivot, and manufacture a replacement on the lathe. Or you could take one of the pivots from PL and cut off some of the extra material, weld up the hole and re-drill a new hole to match Stern's original design. Not cheap, but quite doable.

#5397 4 days ago

My ball shooter guides/stops in the shooter rail are all corroded, pitted, and have faded chrome. I thought I saw some for sale on one of the pinball websites but can't find it now.

Does anybody know if these are for sale anywhere?

IMG_7083 (resized).JPG

If not, I am going hit up Kerry to see if he would make some from polished stainless. I love bling.

#5398 4 days ago

I haven't found those for sale anywhere and I've hunted. Seems easy enough for Kerry's abilities. I'd be in on a couple more than likely.

#5399 4 days ago

I would be in for at least two sets of sling shot arms maybe more...

#5400 4 days ago

Well it was time to paint that Witch blue. Dark blue tomorrow if the paint sets up nice and hard.
