I've gone thru a lot of EH 6922s in my BAT 3iX. They always get noisy after 6 months or so. I've found J/J quieter and perhaps a little better in tone. I've been using a quartet of Amperex orange globes for a couple years. Very nice tone and they are still pretty quiet, though I do worry about sourcing these for a reasonable in the future.
Electro Harmonix 6922 pre-amp tubes
Anybody try any of these Electro Harmonix 6922 pre-amp tubes silver or gold pin tubes being advertised on Audiogon in there preamp? How do they sound? I need 10 6922 in my preamp. I was thinking of trying 8 silver and maybe 2 gold pin or a couple of NOS tubes for the important ones but I don't anything about them.
