    Vague question, I know. Are there any threads out there indicating how to determine what to replace, what to replace it with, and how to replace it?

    Last year I bought an MC2150 from AudioClassics and it's a terrific amp. This particular one is in good condition but arrived with two small weirdnesses, which I was reminded of recently when I moved the amp: 1. On the rear chassis, the white serial number area is blank. I highly doubt that...
