Tube preamplifier lifespan


Do tube preamplifiers, excluding tube replacements, have shorter lives than solid state preamps?

i'm concerned, since i traded in my 20 year old Bryston preamp (still under warranty) for my 'retirement' system

the thing that confuses me is that i've heard that Mcintosh preamps, using full vacuum tubes last forever. where the BHK preamp only uses two small tubes on the input and mosfets on the output

dunno, but it makes me worry since i have the matching BHK 300 monoblocks each with 2 input tubes

it's not the tube life that i'm worried about, the 12au7 tubes are relatively cheap , and there are only 2 of them. it's the comment that the design of a tube preamp won't last nearly as long as a solid state preamp

exactly , Mcintosh amps last for a very long time, why would PSaudo preamps and amps not last for as long?
