Fireball 2 Sound Issue

(1/3) > >>

FrizzleFried:
I picked up a Fireball 2 today.  In 'CHIMES' mode... I get all chimes... and voices.  I switch to sound effects with background sound and that is where the problems hit... most sounds are non-operational... I get a sound from the pop-bumpers...and the slingshots... but nothing from the roll overs... drop targets... etc... about 3/4 of the sound effects are missing... and the background sound isn't working.

Whats up?  Again... the chimes all seem to work when in CHIMES mode... so I know the switches are working (plus the score increases obviously)...

FrizzleFried:
UPDATE: The sounds ARE there.... but very very very very low volume.  Did the amp go bad?  Since the chimes and some effects work...I can only guess there are multiple channels and one or more of the channels went bad... suggestions?  Recap?

I had an identical issue with same symptoms on my Spy Hunter, the VR on my cheap squeak board was dirty.

There are two VR's on the S&T...one for voice the other for sounds.  The one for sounds includes the chimes...which are working.  :)

The pot IS dirty and will be replaced as Bob includes them in his S&T rebuild kit... which should be here tomorrow.

FrizzleFried:
Fireball 2 is a S&T...

...and since the thread title says Fireball 2...

;)

FrizzleFried:
Welp...

sucks to be me.

I'm still having the same issues.  I've re-capped the board.  I tested R41 (196.5K) as good... I replaced the pots... I pulled U13 and U14... added sockets and tried to switch them... unfortunately the problem didn't follow the chip...it remained the same...

...I'm now dumbfounded.
