It sounds like you have things well under control. Like you, I hate to give things up and I am very appreciative of Yamaha amplifiers. I got Yamaha C4 & M4 pre- and power amplifiers in 1979. I gave them to my son's friend in 2000 just prior to moving. The amplifiers still worked fine. The only issue is they had these square buttons that would light up when depressed. A couple of them would no longer light up.
