This one should be right, as long as the parts book is correct

EDIT: This was not the right parts info, it was from a different audio board.

Thanks guys
So basically just upgrade the volts on the cap

Capacitors C26,28,46,47 (1µF 35V) are all operating on the same voltage (+25Vdc and - 25Vdc) and have the same age.
Best to replace all 4 if C26 is already burned up.

Can you hear a sound quality difference after re-capping a sound board? It is mentioned on pin wiki that at their age the caps are at the end of their life span and replacement helps the sound. I usually try not to tinker too much with stuff that is allready working, but if it the ears can appreciate the improvement. . .
