It seems there is a lot of Williams sound issues from using the search function here. I had a bad driver board that had been fixed SEVERAL times it appears. I purchased a Rottendog power supply and the same fuse popped so I sat it aside needing driver board repair. I went ahead and purchased a Rottendog MPU/Driver combo after he got the system 7 working. I installed both new boards last night and the sound works but the volume is really low. I checked the pot on the sound board and it makes no difference. I also turned the overall volume control and it makes no difference also. I can hear all the sounds and the heartbeat and they are all working. When I hit the sound test on the sound board, all the sounds are coming through one at a time like normal. I looked on the speaker and it says 4 or 8 ohms. The originals are 8 ohms, right?

From reading the pinrepair.com site, it says the sound and speech boards have their own power supplies and they are basically their own system.

The speech was working O/K with the original boards except it would just start saying gorgar gorgar gorgar sometimes and I was thinking the connector might be the problem. The volume was fine. Since the sounds are sounding correctly, I dont think it is the connectors that are causing the low volume with the new board.

Anyone have any ideas.
Thanks

There are 2 volume pots in the game. The one on the sound board is a mixing pot that mixes the levels of the sound effects and the voice. You want to achieve a fairly equal balance of the 2.

The 2nd pot is located in the cabinet about 1/3 of the way in on the left hand side. It should be near the roll tilt mechanism. This pot controls the overall volume of the game. That pot may be bad if you have tried moving it back and forth with no change in volume.
 
I checked both pots the one in the back box on the sound board and the other one that was in the bottom cabinet, it has been moved up into the back box also. Other than that wire being shortened and a new connector installed, all the wiring in the game seems "hack" free and it was working like that.
