Tube amps can last a long time because they are fairly easy to repair. Solid state amps, on the other hand, can have their lifespan limited by parts becoming obsolete. Lot of amps made in the 90's used transistors (very good ones by Toshiba and Motorola) that are now no longer made. As long as parts are available, solid state amps can last forever. (Some would say the capacitors go bad, which they can, but for the most part if they are good quality they will last years. The power supply caps in my vintage 70's Marantz receiver test like new to this day).
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!
