lol, yes, there are a lot of guys with basic knowledge with amps, and electronics, but you really have to know your stuff before diving into repairs for a customer base. i men, i can diognose and repair them with a lot of the problems, and do some nice solder work, but i learned my limitations, and stay away from the bigger jobs, like monitoring and logic circutry, etc.... and just stick to the simple things, just because i like it. bigger stuff, i ship it right out, or put it in the "ship out" pile..... sounds like mike ma have not thought about this ahead of time, and got way past his limits for both work load and complication, and just couldn't man up to send the stuff back..... if i wanted to get better at the bigger tasks, it would only be on equipment i own.
