tube amp info

Just to give my two cents worth. I would not leave any tube equipment on 24/7 especially amps and pre-amps. SS pre-amps are fine left on 24/7 as are ss cd players; I would not leave ss amps on 24/7. I have all CJ components (tube pre and ss amp) and this is their recommendation as well. My cd player is a Sony SCD-1 and I even turn it off.

Well, if you're supposed to turn your amp off before your pre, how do you turn your tube preamp off if you were leaving your SS amp on?

Quoting from the "TIPS & ADVICE" section of the owner's manual to my VAC Rennaisance 140/140 Mk. III tube amps:

"How long should tubes last? It has long been known in professional circles (and probably now forgotten) that a [small signal] tube such as the 12AX7 will display BETTER performance characteristics after TWO YEARS of CONTINUAL operation than when it was new. In normal use it is not unusual for a low level tube to last 5 years or longer. Output tubes [i.e., power tubes used in tube power amps] are another story, as they are continuously providing significant amounts of current." (Emphasis original).

Well here is another 140/140 owner needs to retube the 300B's (16) soon. Are the EH gold grids a decent choice.
