Re: Thanks Gearjoneser!
I know I sound like an opinionated A hole, but tube amps deserve nothing but the best.
You can search far and wide for N.O.S. tubes, but the reality is that if you find a tube set that really works, and is the best modern tube companies can provide, you're doing pretty good. I see guys spend ridiculous money on esoteric tubes on Ebay.
I've actually pulled out Mullards, replaced them with Svetlana and Teslas, and sold the Mullards for enough money to buy two sets of those. The end of the cold war really helped the tube amp market, cause you couldn't get Soviet and Yugoslavian tubes for this price, 10 yrs. ago.
