I used Telefunken in mine. I found the 6DJ8/ECC88 to sound better in the SP9 MKII , and the 6922/E88CC to sound better in the MKIII. They both lasted more than five years in standby.
Tube life in preamp. Please help
Hello-
Using an Audio Research SP9 and I've shut it down each time between listening sessions.
I find however it sounds better if I leave it in the standby position.
How much does this lessen the life of the two tubes it contains? They were Amperex and not cheap.
Please advise. Thanks!
