most amplifiers that have had a switch in the bias eventually go full nuclear and fail.
Probably the worst place in an audio circuit to put a switch.
It might take 10 years or more for it to happen and usually does take 10+ years....but consider it a done deal.
Tick tick tick......
You can’t afford to have those contacts in those particular switches to ever suffer any lack of contact, but..eventually they do.
It’s like all switches. They get dirty, and have contact issues, eventually. No exceptions that I’ve ever found. So, logically...
I'm not saying it's a deal breaker, as things should be good for quite a while....
