The "tubemonger" has some Matsushita 6922's that are not in the same league as the Siemen or Amperex but sound better to my ear than the Sovetek or EH. They were selling for 50 buck a pair. To my ear the BAT sounds best with the Amperex 7308. I have used several 6DJ8 types and they don't seem to last long before becoming very microphonic.
