Try the 6992 TESLA NOS gold pin. I use EH gold pin and Tesla on my Graaf, but in my experience I can tell you the tesla tubes are much better, it`s a substancial improvement.
Electro Harmonix tube opinions
I need your opinions of the EH tubes.
I have to buy many 6922, KT88 and 6550 tubes and the EH have excellent prices.
Anybody could compare them with other new Russian tubes like Sovtek, SED or Tungsol ?
About the 6922, EH have a gold pin version: anybody use them ?
I will apreciate all your opinions and suggest.
