Perhaps one of you fine gentlemen have come across this issue before.
I was cranking my system pretty hard (0db+) when my main speakers shut off.
Startled by this, it took me a few seconds to get out of the recliner.
About the time I got to the gain control, the mains roared back to life.
As I stood there watching the VU meters on the M-500, the mains shut off again.
I lowered the gain a "click" or two and waited.
After a few seconds the mains came back on and stayed on for the rest of the CD.
Now I recently made a change to my system based on a comment from TNRabbit.
For years I powered each satellite via it's own M-500(t) with both amps bridged in mono.
The change was to power both satellites using only the one M-500 running in stereo.
(I made no change to my subs which are each powered by a single M-1.5t.)
So, after the CD finished playing I decided to switch the M-500 for the M-500t.
I went back to the same CD I was listening to earlier and set the gain to 0db.
I continued to raise the gain intermittently to +3db without incident.
Just for the heck of it I switched back to the M-500 and set the gain to 0db.
It played fine for about 5 minutes before it started cycling off and on again.
Any ideas about what the problem is and what it will cost to fix it?
Is the M-500 worth repairing or should I look for another M-500t?
