I want'em. You got PM 
Hi Jon
My PM was at 4:55, so I think I beat you.
Just wondering if someone else got in a PM before mine.
I have wondered how my k1000's would sound with 2A3 tubes.

Well, if the OP decides to sell it to you, I'll buy them from you after you find out for yourself 2A3 is not enough juice for K1000's

I've tried most topologies, and around 5 to 6 good watts is the minimum for K1K IME. Me, on the other hand, was planning to try 2A3 with my Sennheiser HE60 electrostats with an adapter transformer.
