Model: Sorcer Striker
Symptom: No audio and a blown cap

A note sent with the board said a cap had been blown by a faulty power supply in the cab.

Replaced 8 caps, the MB3730 audio amp IC, an LM324 op amp, and an LM358 amplifier IC. Every chip powered by +12v was bad and needed replacing. Luckily the 12v supply was only needed for the audio amplifier section of the game.

Model: Battle Garegga
Symptom: Sound Section issues

Board came in with the description of "clean up sound section." Replaced 6 electrolytic capacitors, 1 audio amp IC, removed/reinstalled 2 poly caps, and replaced 2 shorting jumpers with correct resistors to keep the amp from running too hot. Installed mounting hardware for the amplifier IC and tested the game.
