Power blackouts - problem for tube amp & speakers

I would see this as a bigger problem with a solid state amp, simply because when the power comes back on, it will be possible to thump on account of the preamp.

Most tube amplifiers should take a power outage in stride with no worries- I know ours do!

The controversy is over putting something between the wall and a power amplifier, which most manufacturers will say is detrimental to the amp's
performance (power limiting, extra noise on the line, etc.). I have solid state equipment that has a computer circuit that will ALSO put the components
in standby and have to be MANUALLY reset before i can play music again.
it is very annoying and if the circuit that must sniff the line 24/7 (even when the amps and preamps are not in use) should finally wear out, my precious stereo must be packed up and sent to a repair facility. And therefore, many dollars spent later, i get to listen to my system again.
OTOH, My central Air Cond. and refrigerator also draw a lot of power, but they will rarely break down under similar circumstances. Welcome to high-end audio...

^^ next time that happens and you have to send the amp back, have the manufacturer fix it so you don't have to do that. That's nothing to do with high end audio and everything to do with poor design.

^I think Ralph is right on that one.
