hi all

a friend called me with an issue they are having with their barb wire pin. i havent been to their house yet to check on whats going on but they tell me the sound volume is good when they first start playing the game but eventually the volume will do down on its own. anyone have any ideas on what is going on? maybe some things to check when i get there.

how do i check the ripple? if its bad how do i fix it?

all voltages check out on the aux power supply board (amp board). i wonder if the amp chips or the quad opt chip is going bad

i tested the the auxillary power supply on a different machine and it works great. so i guess i am back to testings everything after the amp and before the amp.
