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. Title: Re: Raizing / Eighting Games Post by: channelmaniac on August 07, 2011, 11:40:05 PM 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. Title: Re: Raizing / Eighting Games Post by: channelmaniac on February 20, 2012, 04:47:42 AM Model: Battle Garegga
