Amp shuts down with a signal.........

I had a problem with my main amplifiers Thursday night, and when I replaced them with a single 5 channel amp (a temporary move) I had something strange take place.

When I turn the amp on with NOTHING connected, it will stay on with no problems. When I connect a pair of speakers, run the volume at a very low level, it takes about 1 minute, 42 seconds and it will shut itself off. When I play the music at a more normal level, (after I have turned it back on) it will shut down within seconds.

Does anyone have ANY idea what I should look for?

Unfortunately, this is one of my favorite amp/preamp combo, the Golden Theater GTA-1 (matched pre is the GTX-1) that are absolutely wonderful, especially the processor in 2 channel! Heck, the amp is pretty hefty (provided it works) at 200 x 5 @ 8 and doubles to 400 x 5 into 4!

Yeah, the one problem with Golden Theater, they are OOB.

So, if anyone has any suggestions, please let me know. I took the cover off, and I see wires, metal, more wires, plugs, capacitors, this, and thats'.

Thanks

Binaural, thanks.

I placed this GTA-1 on top of the other amp I am using, which has not problems. Same ICs and same speaker cables.
I keep switching back and forth, and only the GTA-1 has a problem, and only with a load. Odd?

Binaural -

Well, I gave is a speaker ONLY load and it shut down. Therefor, next I swapped out the speaker cables and it worked for about 10 minutes. I disconnected it and reconnected my other amp for comparison listening. After another 10 minutes, I reconnected the GTA-1 and it shut down.

I will try the ICs only this time. I might be sticking with the Jeff Rowland Model 7's, I have no issues (now) with them!
