I have also found telefunkens to be the tube to beat. My amprex's had a hot top end that sounded a bit unnatural.
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!
