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?

@soix, Thanks for the information.  I don't believe that it is a constant temp flux, because one isn't turning on an off like a 3 year old.  It is turned on and let warm up.  Hence the word warm up.

however, I appreciate your input and will look at your other post/responses.

any good information can't hurt.

 

enjoy

@minorl I think I kinda misspoke — I meant that every time you turn your system on the temp of the internal electronic components go from cool to warm/hot, and then when you turn it off the reverse happens.  This is the temperature fluctuation I was referring to, not some constant fluctuation during operation.  Just wanted to clear that up and sorry for the confusion. 

1) Valve amps should not be left on since the life dependancy of the tubes
is affected.

2) Class A amps should not be left on due to the wasted energy and heat
that they generate.

3) The rest depends on whether your amp has an inrush current limiter or not.
- If it does (your lights do NOT dim when you switch it on), then turning it
off would be ok.
- If it does NOT however (your lights DO dim when you switch it on) the
amp should be left ON all the time since considerable stress occurs at power up.
