Welcome @tgoggans! Your dad, and now you, clearly had some great taste in gear! Not that the Sherwood was any slouch, either.
Sounds like you have a nice setup, there - enjoy!!!!
I can't offer much in the way of technical advice, but there are plenty of folks here who can offer advice or assist in fixing your components. I'll let the appropriate folks pipe up for that, but if they don't - ask, and someone will, or will direct you to Greg (Nahash5150) at nelionaudio.com .
