I have a Kenwood 106VR in my "computer room" that's been on 24/7 for...just how old are these? Somewhat over 10 years I'd guess, from when HT sound was still 2 channel anyway. I never turn it off...and the volume doesn't fade...so was a good deal as far as longevity.

Agree there are likely caps that need replacing, they deteriorate in just about all gear over time. If it takes MONTHS for the problem to manifest, forget about easily narrowing the problem down, but you can pretty much guess the main power supply caps need some attention, among others. It is often difficult to find exact replacements for the large PS ones because mass-market gear typically has custom ones.

Fixing this could be a real time-consuming effort, probably hard to justify unless fixing electronics is a hobby...
