OK to have power amps powered w/o spkrs.?

I would not think it would bother any modern amp to run without a load. If you are worried why not get a couple of resistors and connect them to the outputs? You are not feeding any signal to them so I don't see what good they will do outside of relieving worry. But that is a legitimate purpose. You should have been around in the old days when you could blow the output stage when the amp was unplugged. I have a feeling that that advice may have been directed at some of the more exotic circuit designs. Amps that run well into class A are a law unto themselves.

Stupid me, I forgot the obvious, ask the manufacture of the amps.

Thanks Stanwal... I think I've answered my own question. I guess that's what the "search" function in forums is for...

From what I gleaned off the thread, it's a NO DON'T DO IT...

Although, I"m not sure it applies if I do not have a signal (source) going through the amp while not connected to a load/speakers...

but better to be safe than sorry.

Are you purposely not telling us what your amps are? This info could factor into the correct response.

In general, if it's a recent design (last 20 years) solid state amp, then leaving it on won't be a problem. Tube amps are a completely different circumstance. Additionally, I would be wary of connecting or disconnecting loudspeakers from a powered on amp. It could result in a loud pulse coming from your speakers.
