You have a very nice set-up as well, Tympani!
"...Have you tried any NOS tubes. My current favorites are the Siemens 6922's (60's vintage).."
No, I have not but you have tempted me as my existing tubes are 3+ years old at least - It still sounds great though :-).
Did you replaced all 6 6922s at once with the Siemens or just some 1st? I understand from Keith tubes 4 & 6 are more sensitive to noise then the others.
BTW, where did you purchase your Seimens & what did they cost? 2nd, have you tried "cryoed" 6922s? Ta.
