I have updated the tube page with available tubes.
I have lots in stock including:
Tung-Sol 6550, EL34, EL84
Electro-Harmonix KT88, EL34, 6CA7, EL84
Svetlana KT88 & 6550
Gold Lion KT88 quads (only a few of these available).
If you've been waiting to pick up a new quad for your amp, now is the time!
