Tech: Donkey Kong - Burned Up Audio Board

[Guest]

Archived from groups: rec.games.video.arcade.collecting (More info?)

I did something stupid last night. I forgot to put the back plate of
the monitor on that has the audio connectors on it. I plugged in every
wire and fried my sound board on the game board.


Questions...


1.) Does anyone know the value of resistor R13?


2.) I took out a transistor as well and a couple caps. Does anyone know
what else is in this circuit that I may want to replace?


3.) Can anyone think of other componets to test that may have been
affected?


Thanks,
Todd

Todd,

I once plugged the two audio connectors on the sound board in backwards and
did similar damage. I replaced the burnt parts (caps and transistor) and it
worked.
