might be lighting, but the top of the board where the speaker traces pass looks to have damaged the board by swelling, it may be more extensive a repair than first glance.
What's the amp doing or not doing correctly? I'd support Ricky even though I repair my own amps in SoCal. He does great work and an overall great honest guy.
I got 95watts RMS per channel at 4ohms with a 60hz sine wave (pretty brutal), when I do these types of test I always place two fans right beside the amplifier (with no bottom cover to allow air to cool the inside as well as the heat sink. Also got two fans on the dummy loads).
With music I got dynamic peaks of 140watts (4ohm/per channel). Am sure it can put a bit more power @2ohm stereo, don't know if its recommended though. I am limited in dummy loads so I couldn't test it at 2ohm stereo.
Was at 62amps of current with the sine wave test and 12.99v.
