I shed a tear, Russian sellers not sending what you ordered? Totally unheard of!
That's not very nice. I may have to rethink my vote.
I don't use those tubes, so while I'm feelin' bad for AC, no tears for me.
I'm gettin' ready to send a batch of my Foton 6h8c's to Cryo International for a deep freeze. Quite a while back I did an A/B comparison between identical tubes, one pair cryo'd and the other not. Pretty audible improvement in the cryo'd ones, but not like night and day. Be interesting to see what happens with the Fotons.
