Leaving my amplifier on ok?


Would it be ok to leave my amplifier on all the time if I want to extend the reliability of the amp? Many amplifiers ar Class A, high current bias and tubes might be a problem if energy consumption is a factor. Not to mention Excessive heat from bias operation. Is it possible to extend the life of the amp with leaving it on all the time?

You can always compromise and turn amp on before going to bed Thursday night (for a big weekend listening session). Turn it off Sunday night.

I read an unbelievable story about a NYC dweller who left a pair of McIntosh monos on for 35 years because he had them in an impossible-to-reach location. Maybe I dreamed this...

@dweller , that story rings a bell. I have read that too. But it was just that this dealer or reviewer was helping out a widow whose husband had died and was buying the amp from her. The best part was that the amp sounded fine even with the tubes being ON for that long. I believe it was in Stereophile somewhere?

I have  five amps I use every day. There are 4 d amps that I leave on 24/7. Also in use is a single-ended 812 amp, that is in use most of the time (cuz it's so good!)  There is an SET 300B that is used rarely (it makes a good back up when necessary).

@highend64 seems to have already answered his own question.

Anywho, here’s my take. Give the ones that generate heat room to breathe. Chances are all will be well.
