On pinwiki and apparently in a service bulletin I'm yet to bother to look for, It recommends removing C37 and C45 from the DCS sound board to remove scratchy audio or mumbled speech and improve the sound overall


I'm just curious who here has done this? and what were your results? any significant improvements?

It only affects some WPC-95 games, but it made a huge difference on some of mine, Junkyard I think the most noticeable.

The results were a far less tinny/harsh sound with sfx at higher volumes.

I've never noticed a problem on the WPC-DCS era, but that's interesting.

If you know what to listen for is really noticeable.

I always find JM hard to listen to actually, I think the bitrate is lower than many other titles and I can only describe it as "noisy"... "harsh"... "sfx overload"

In contrast something like Flintstones crystal clear, if you have it up loud it the jackpot fanfares etc sound great

Nigel, just done this on my WCS as the callouts are muddy but music was great anyway.
Didn't change much if anything (but I am deaf in 1 ear and the speakers have silly acrylic footballs in front of them which I'm about to remove that I'm sure won't be helping on mine)
If it's for your Demo Man, this game seems to be on of the ones mentioned on Pinside that it does help a lot apparently mate.
 
Thanks Crewey. Shame it didn't help too much on your WCS. It was worth trying anyway I reckon as there are no negative effects, it will either improve the sound or do very little. Nothing to lose really

In the latest pinball shenanigans YouTube video he's working on a demo man and he sent his boards off to his board guy who removed the two caps and quoted a service bulletin for his reasoning. So after a bit of digging, as you say, I found out it can have a significant difference on demo man and presumed it would do the same on all WPC-DCS machines.

Most of the later WPC-95 had the caps C47/C51 removed at the factory before shipping.

I'm going to remove mine in DM later and will report back.
