Re: tech bally sound module as-2518-50

It's jumpered coerrectly just like the good working one I have here is.
all caps and jumpers match.

I have 2 Kisses here for repairs. One cpu died the other the rectifier board
fried and killed the cpu and the sound board. repalcement cpu and rectifier
boards are in and working.

repair.

you
will.
all else in game is good. board is correct for the game Kiss.
I have tried another one and it works fine.

I'd like to repair or replace but don't know where to start.
I checked the marvin repair guides but they don't specify this exact
board.

any help appreciated

Hi,
Had the exact same thing with an AS-2815-32 which after swapping all
the cap I moved onto the chips, the chip that was bad was the 74LS93
chip thats U8 or U11,
I got it by just changing each one till I hit the problem. I had
static with clunks where the tones should be at full volume. You
should also check oliver's site ( search for oliver his address ends
in .ch)
Laters,
Tim.
Mail me if that dont fix it as there are a few other things that it
might be.- Hide quoted text -

HI,
Just for my peace of mind please tell me where the jumpers are on the
board, kinda top left.
Also next to the big connector strip about five pins down running left
there is a row of resistors leading to two chips, how many disc
capacitors in that row?
By the way, Did this board ever work? I mean did it stop working while
you owned it?
Tim
