Stampede
Stern Electronics, 1977Hey guys, I have a Stern Stampede with electronic sound. Everywhere I look for a Stern Stamped, it shows this game without the electronic sound and with chimes/bells. I'm curious how many actually had electronic sound, and it appears to be made this way because it has a decal in the back part of the PF that says "Electronic sound" The sound board is crap and I am trying to find schematics. Does anyone have any insight?
If you could post a pic of the sound board, we could verify Cheddar s theory...which I think will be correct.

If you really want to repair that board, I'd focus on the electrolytic caps and those two POTs.
The other parts, resistors, 3X 4N25 optocouplers (interfaces to EM voltage), 2X LM3900 amps, and one TBA820 amplifier, are still available, but chances of failure is, IMHO, much less than the caps and the POTs.
