Just curious about what brands, types, and exact pre tubes you use in your amps?

Matchless Chieftain 2-12 combo. 2 Svetlana =C= EL-34's. Preamp is NOS Mullard ECC83's. Reverb drivers are JJ ECC83's.

Fender Bassman LTD. (just sold) GT 6L6 GE's, EI Gold Elite 12AX7's. I sold it with all the stock Fender tubes.

Peavey ValveKing ~ Two 6L6GC and three 12AX7 tubes
I have JJ 12ax7s in my Triaxis and JJ 6L6s in my 2:90.

I think I have Mesa branded EL34s in my 2203 and 12ax7s as well. I'll have to do something about that one day.

I have a pretty large collection of old stock tubes. Mostly 6L6's 12AX7,AU7 and AT7's. In or around 1988( Remember the Cold war?) I read in a guitar magazine that in 15 years there would be no more tubes. Me and a friend use to go out on garbage night looking for old electronic devices to raid the tubes from. In 1991 when my grandmother passed away. While clearing out her Apt. I found a large box of all preamp tubes. Mullards.RCA's Phillips and Amerex. My Grandfather worked in a electronic supply store in the 60's so I guess he alway's kept a supply on hand. And he had the foresight to know his grandson would grow up to be a tube hoar.

mesa branded EH 6l6gc
