These are big tubes, are they like power tubes where 3000 hours is a reasonable assumption?

I don't count hours here, but I can say I got several years of hard rockin' on the current one. That's also driving a quad of KT120's most of that time. Also picked up on a spare while I had the chance before the price bloomed a bit back.

I'm still highly impressed with your work on this amplifier!

More importantly ... so am I !! ;-}
I've also got a Mullard GZ34 here that racked up quite a few miles before I scored the GZ37. At the same time, I ended up smoking a couple Chinese tubes fairly quickly. Lot depends on how well built (or overbuilt?) the tube is.
