I have accumulated a good sized group of mainly unused USA 6AS7G and 6080 tubes over the past several months (in and amongst various tube lots), but I need the Russian or Chinese varieties for my Atma-Sphere amps.
I am willing to trade one for one for anyone interested.
I also have other tubes I can use for trade as well (power/preamp/others).
Anything I provide will be tested on at least a Weston 981 III.
