UPDATE (yes AGAIN):
Good news: I FOUND AN ULTIMATE FIX FOR THIS PROBLEM
Bad news: it's a huge pain in the ass
After talking with people on the DIY audio forums I received a useful suggestion that I was pondering myself...the ground line could be the problem. Lineup on the forums suggested I completely isolate all grounds from the amp away from all video grounds. This is no easy task since traces and grounding run rampant throughout the board and around the amp. I've been cutting and dremeling around the ground areas of the amp for the past 4 hours...I finally isolated them enough to constitute a voltage drop (not COMPLTELY isolated I guess but no way in hell I'm spending more time drilling). I plugged it in and made sure the amp wouldnt turn on unless I wired the AMPS ground to the regulators ground (shared by the screen, bot only at that ONE point).
Voila! Even at the loudest bass heavy gun shootin sounds the sync deformality was very very hard to notice. With some caps on the power lines I won't be able to see them at all. It's a HUGE difference!
Appearently this problem is only evident when the amp is working harder (like with the PS2). When the input signal is weak (like my Genesis) the sync corruption does not occur. However, voltage spikes are present when the gain reaches higher levels...but with this fix you can still listen to everything at full volume! The amp actually has a decent amount of power once it's used to its full potential
Moderator: Would you consider adding this fix to a Sticky? I'm a moderator on other Benheck forums, not this particular one so I can't do it
