thanks!!

My guess is caps going bad in power supply.

I had an ep500 amp fail twice. First time was under warranty second time I traded the ep500 in to axiom under the upgrade program and got some new mains. bought a used ep600 thru zbay.

I did leave the unit powered up 24/7 and my guess is the constant heat got the caps. It even puffed a little smoke once but kept on working for another year or so. YMMV

otherwise start contemplating if you want to spend $748

also, turn it off for 2 days to completely cool. then turn it on. probably wont start popping till it heats up.
