Saying you do this to many companies does not make it the right thing to do. If you're truly attempting to help, why not contact the manufacturer directly and offer advice. Your sense of truth and professionalism is a bit skewed spritzer. I mean common man, who the hell opens up an amp and posts what you post. You spent a month of your life talking about this minor project in open forum in an attempt to come across as some self proclaimed expert and at the same time attempt to discredit the manufacturer, you said it yourself in the first post. So you swapped a few parts in an existing amp- Your'e a damn hero man!
I take it you could care less if others are hurt in the process. It's all about you anyway, isn't it?
