Quoted from paynemic:

I would assume this works with an lotr? Has anyone needed/used this mod on it?

Yes, i did. Works great for lotr too.

#52 5 years ago

Thanks sed6. I received my set very fast and they work as described. It was great to see a useful product for a reasonable price.

#53 5 years ago

I saw this and thought these would be pretty simple to make. But $10 shipped? Forget that, set ordered. Thanks sed6.

Quoted from Lermods:

I got the connectors today, but my board, which is original from 2003 looks a little different. R110 is not at the top and is down below next to 106. Am I still good to make the connections. Just want to be sure since the instructions show a different picture.

So my lotr board looks like this too. I put them on 106 and 110. I guess my hum wasn't too bad because I can't tell to much difference except it lowered the main volume a lot (so I turned it up).

Thanks all. Glad everyone's having luck with these. Auctions ended. I won't be making any more for a while. I'm going to post up my instructions that I include with each set. They and the video is all anyone who endeavors to needs to make and install some.

#57 5 years ago

I'd buy some if still available.

Quoted from sed6:

Lots of speaker hum threads here and none seem to show a good fix. My TSPP has been humming in attract mode since day one. Of course it's not noticible during play, but when the room's quite the hum or buzz drives me nuts. Some reading here and some googlefoo lead to to RGP where there are several fixes, some dating back 12-13 years. I went with the adjustable pot mod and this completely eliminated my speaker hum. Check out the vid below for how I did it and the see (hear) the results.

Very nice. What gauge wire did you use for the red and black wire?

Made up a set today and it worked great, the humm was driving us bonkers! Clips only slide on one way so make sure to bend the wire on the bigger side or it will not snap up good.

Has anyone tried this in Star Trek Pro?

#63 4 years ago

I don't get the hum in my ST Pro like I do TSPP...you do?

#64 4 years ago

I don't get a hum with my ST Pro. I did do this mod on my Stern NFL and it helped immensely.

#65 4 years ago

It's not nearly as loud as TSPP but it's got a buzz... TSPP and DESW used to have a noise contest but after pin2dmd and RasPiSound Star Wars is silent.

Ordering one for TSPP thought I'd give it a shot. Any guidance on where it goes in ST would be much appreciated

#66 4 years ago

I put a PinSound in my TSPP, now not only is the HUUUMMMMMMMM BUZZZZZZZ gone but I have SWEET sound!

#67 4 years ago

Serious question, not trying to be a jerk... is it really better sound? I think TSPP sounds pretty good already (sans the buzz)...good bass, clear and good sounding call outs etc...

DESW is lo-fi at the source and kinda corny compared to OST

#68 4 years ago

I upgraded the speakers too, but yes no hum/buzzz and IMO sounds better

I just finished trying out this mod, and it did lower the hum a lil bit, but i'm still getting quite a bit of hum, adjusting the pots doesn't seem to lower or raise the hum. When i remove the pot from R110, that's when i hear the hum increase, when i remove the pot from R106, nothing changes. I'm wondering if it's maybe my transformer, I tried hitting the top of it like some mention, but that doesn't seem to do anything.

#70 4 years ago

Make sure it’s not the transformer for the fluorescent tube that buzzing.

#71 4 years ago

I bought 2, one for TSPP and one for my noisy Star Trek Pro. TSPP worked as it was supposed to but turned out I didn't need one for STP because my fluorescent light was buzzing like a bee. Led kit cured that one, now the whole collection barely makes a peep (if Big Guns didn't hum...). So, pop the light out and see what happens!

Quoted from pintechev:

The hum/buzz is coming through the speakers and sub though.

This fix still works great. I made some for my T3 and couldn’t be happier.

#74 2 years ago

Anybody tried it on a data east? I *think* JP is the same boards and same issue.

#75 2 years ago

I've just done it on Goldeneye. It was with a brand new rottendog mpu that had so much static it was silly. Just put a pot across R110 and set to about 3.8k and it took most of it away

Did this today and it worked like a charm. Thank you.

Just wanted to stop by and say thanks for this post. I just did this to my TSPP and it is amazing to have that hum gone.

5 years going and still a great tutorial.

I still wonder if this would work on the DE hum...

#78 1 year ago

Used on VND years ago and it helped.

#79 1 year ago

Glad to see this modification lives on and is still being used! I wrote the original write-up 20 years ago and had it hosted on the Paisley site (post #5) but seems to be no longer active. I'm sure a Google search might still find it buried somewhere.

I like the clips and pot idea. I never thought of that when I modified my Monopoly when I bought it NIB in 2001. That Whitestar board just had too much gain in the amp section for my sanity. I'm glad people took and ran with my fix and helped others out.

I would have gone the Pinsound route, but after looking on their site, the only soundtrack for my Whitestar machines I have are the ORIGINAL, so I am going to solder in a dime's worth of resistors into R106/110 this weekend and save $350 on the pinsound for whitestar kit. Not as elegant, or fun, but an OK plan.

My pinsound TsPP package is awesome. Highly recommend it.

I have Ripley’s and ROllercoasteTycoon. Neither have an updated soundtrack....

Just applied this to my The Simpsons Pinball Party and Lord of the Rings and it is glorious. I love that it gives some amount of control over being able to adjust the audio mix. For my Lord of the Rings , I was able to dial it in to where the callouts really stand out more now too. All without that damned buzz. Thanks to everyone who wrote up the guides and found the original fix.

Does anyone sell this kit? I have zero soldering experience and would be much easier if I can just buy this setup.

Anyone else have a different bird where the resistors are right beside each other?

It was mentioned earlier on this post I believe by Lermods.

I think you can also replace the resistor to increase resistance. I would prefer a permanent fix rather than the clip on.
