From my STTNG and works perfectly
PinSound was added (and I kinda regret that?)

This is not the right vintage sound board. BSD requires the pre-DCS sound board.

What is wrong with your original. They are 100% repairable.

This is the problem.

https://pinside.com/pinball/forum/topic/bram-stokers-dracula-sound-problem

I put my fish tales board in and the problem went away. It’s the strangest problem I have ever come across. I did acquire a new board and I’m going to put it in tonight. I’ll let you know if the problem goes away.

#6 24 days ago

Let me know if it doesn’t. I have my original fully working BSD soundboard, replaced by Pinsound also.

I might not want to sell it, but I could send it to you for testing purposes if I’m on the fence with selling.

#7 24 days ago

Thanks Colson

#8 24 days ago

Well, after leaving the game on for about an hour, the problem seems to be solved.

#9 24 days ago

Nice. If any issue with the sound pops up again, shoot me a PM.

Kinda wondering why you guys are so on the fence over your pinsound purchase, In every thread I have read it is all the rage hands down...In reality it is a new board as compared to a 30 something, has the ability to change/modify the tracks, and has stereo capabilities...Am I missing something as compared to OEM?

Because it doesn't, and it is incapable of, faithfully reproducing original game sounds. For me, that's a simple no brianer, and changes the 'Pinsound' from an "upgrade" to a "mod".

I’m not at all. I love the Pinsound board. I’m only on the fence to sell my original board in case I ever sold the game (which should never happen). But if I ever did...I figure maybe the buyer either might want the original board, or might not want to pay for the Pinsound upgrade (mod). Then I could take out the Pinsound and throw the original board back in.

And for BSD, my buddy Dave put together an awesome new Pinsound mix using a boatload of sounds and tracks from the original film 3-disc expanded score, fully integrated with the rule set and modes. It’s killer.

IMO the “original” sounds on Pinsound are really good, but not a perfect replica of the OEM sounds. But you can also tweak them in the editing platform if you want. I really like having the ability to toggle back-and-forth.

I regret buying pinsound for my STTNG. Will not be buying one again

#14 23 days ago

Wasn't a fan of pinsound in my bsd...sold it and put original back in..

#15 23 days ago

Suddenly I am a bit nervous, I was quite excited at the prospect of pinsound, and the ultimate kit was not only quite spendy but also not really something that can be easily changed back after the fact As part of a build...However it does stand to reason not everyone would like it, for one reason or another, I would have guessed complexity would have been the primary dislike...THX. guys.

#16 23 days ago

hardware is great and has potential.

Hated all available versions of sound files for STNNG

RollerCoaster Tycoon would benefit from PinSound, even if you just had every track as Led Zeppelin Stairway to Heaven

PinSound is great for re-theme of a pin.

Otherwise I am not buying One again.

Pinsound was a life saver for me back when I was working on my LOTR machine. At that time, the whitestar MPU/Sound board was not available. A pinsound board was my only option, and it worked out great for me.

To add to this thread, I too had a hard time finding a replacement pre-DCS sound board for my TZ. I think this is one board that is overdue to be re-made. There are a few on Ebay right now, and the asking price seems to be right around $200.

I have been working with someone in Germany to recreate the board. It's been slow going, but it IS coming along.

The DOWN side is that it will still require the NLA chips - the Yamaha and Volumne control at least. The PLUS side is that, it'll sound authentic, because it will be.

#19 23 days ago

I'm fortunate that I have yet to purchase a machine with a Pinsound because the first thing I would do is remove it and replace it with an original. I prefer the original experience. I think it's great and support that there is a replacement for those whose boards need replacing or want an "upgrade" (modification). It's just not for me.

The original boards are relatively hard to come by and often when they show up are more expensive than I would like. So I have embarked on making my own. It's still a work in-progress. The WPC-89 sound board mostly works. I have a small issue to work through. The WPC-DCS board looks to have an issue in the analog section. I have a thread for these if you want more information.

I will say that after having done some of this board reproduction work for just about a year ... I now appreciate why the reproduction boards cost what they do. Component parts are expensive or sometimes difficult to find and labor isn't cheap. If you want to keep your "antique" toy working it's going to cost - both time and money.

dumbass, Looks encouraging. The PBOM on this wouldn't be that expensive, except for a few hard to find parts. It would be a neat "kit" or even bare PCB project (source your own parts).

Add to this list, but I think the hard to source or expensive parts are...
MC3340
X9C503
YM2151
YM3012
CVSD (a 55536 IIRC)

There are only a few scenarios where I preferred the pinsound board over the original. Unless you absolutely hate the music I would stick with an original. Data East Star Wars does sound much better with a pinsound board, though.

I REALLY hope you did your proper research on resistor values, as there were two different versions of this board.

Quoted from Coyote:

True...but it's only 2 resistors IIRC.
The bowler version of this board used a small plug-in PCB at the CVSD. I thought the reason for this might have been that the 55536/55516 were becoming hard to find. I thought, "great...here is an alternate solution to the scarce CVSD". But when I looked into it, the CVSD on the plug-in card was just about as scarce as the 55536. Argh.

Quoted from ChrisHibler:

I believe it's three resistors, two of which have the same value.

Quoted from Coyote:

There are differences between the schematics and the BOMs listed in each game's manual.

I believe that you're correct in that there are two versions of the board (with different resistor values). There are also (at least) two revisions of the board. An earlier revision has a ceramic capacitor correction that is not silk-screened on the board.

Often people don't realize that there are two different resistor value versions and swap them as if they were interchangeable. I picked up a Gilligan's Island with a Fish Tales board. When I put my reproduction board (with the correct resistor values for Gilligan's Island) in the difference was obvious. The reproduction board allows dynamic switching between the different value sets and with that feature it's REALLY obvious.

Correct. Those two resistors modify the pre-mix volume of two of the three audio channels. Game's ROM and Sound ROMs are expecting these values - for example, if you put a pre-DCS sound board from Hurricane or Terminator 2 into Twilight Zone, you're gonna have some VERY tinny sounds.

So as long as you know about this, then great. The person I'm working with in Germany just added two dip switches. There were only two resistor values used, and they always matched - 56k and 150k. (WPC schematics had it at 120k.)

#27 22 days ago

I have seen preDCS sound board with channel 2’s 47uf capacitor unstuffed. And, some testing I’ve done indicates that channel 2 isn’t used. Just an FYI.
