My Pass Labs Alepth 1.2 Class A monos have two decades on them now. The filtering or power supply caps are the soda can electrolytic type caps; I’ve seen the moniker computer power supply caps used to describe these large caps with terminals on the top. I’d love to see if replacing those old style caps with modern low ESR say polypropylene and foil film caps or something like that would bring about an improvement.... That is just conjecture on my part; I should just leave it to Nelson, the true expert, to upgrade because if anyone would know, it’d be the man himself, Nelson Pass. The great thing also, he is within driving distance of me so I don’t have to ship my gear and let the UPS fellas beat up my stuff!
amplifier longevity
Is there any difference in longevity and or reliability between valve amps and solid state amps?
I thought that perhaps design differences between ss and tube amps might be a factor here.
Specifically I am considering the valve amps by Rogue Audio vs. the solid state amps by Luxman, both great brands in my opinion.
Thanks!
