Victor wrote me that all six 6SN7s perform the same function and close matching is unnecessary. These tubes take 600V at start-up, which may be a problem for some types. I'm not much into NOS tubes; IME Tung Sol reissues surpass EH. The unit can be decisively improved with lite modding-- which I recommend over investment in NOS tubes.
BAT VK75 Tube placement?
Hi!
I have a BAT VK75 amp and I am aboat to changed tubes and wonder if anybody can tell me how to place the 6SN7 tubes. I have EH "Gold" in the amp now but I have purchased some RCA NOS and wonder if its any differece to place the best tubes in front row (2 tubes), or in the back row (6 tubes)?
Is there any use in use different 6SN7 in the amp?
And last question, where to place "mathed" tubes? One on each side, or both matched tubes on the same side?
Thanks!
Jack
