Carver and Tube Life

I’ve been looking at Bob Carver’s statement tube amps, the Siver Seven 700’s.  These massive tube amps designed by Bob  have been around for years and the latest version of his 700’s can now accommodate KT120 output tubes and his best output transformer design.

EACH mono block uses 20 KT120’s! That’s 40 KT120’s total when it comes time to ‘re-tube.’  However, according to his description these KT120’s should easily last “50 Years”.  Is that truly possible???  Can the output tubes really last that long ?

Doesn't Bob offer not only a 20 year warranty on the amps themselves, but tubes also?  That would really ease my mind.

KT120/KT150 tubes aren't cheap, especially if you have to replace a bunch.

+1 on Al, (he's our treasure), no you can't have him :-)
