coming from you...means a lot to me...
thank you

For you PL400 II (Non-WOPL) experts, a guy asked me what would cause the display on one channel to light up the first and third LED all the time? The middle LED module stays dark. I usually toss them so I've not had a need to troubleshoot one.

it was a good experience...
criticisms, critiques, observations welcomed...

It is far easier to guide you through this than the damage if a blowup occurs...

Gene, you need to spring for a hogs hair bristle brush for cleaning your boards. You have fibers all over the back of the board from whatever you use to clean with.

A message like this is far preferable to the one asking what is wrong with my amp, with no clues, no pictures, no readings, etc.

Good work Gene. Uneventful bring ups are the best...
