Classe CA100 - Static, Cut Outs when cold. Ideas?

Had the same problem with a Classe' CAP 150. Amp would cut off and on when cold, left it on all the time and had no problems. It went back to Classe twice for this problem and both times they said they repaired cold solder connections.

FWIW, I have a classe ca-150 and have never had a single problem with it and love the sound of it.
I say just try leaving it on 24 / 7. It's kinda like when you go to the Dr. And tell him it hurts when you do "this", so he says "well don't do that!"

I know this thread is many years old, but maybe people can still use this information.  I have a CA-150 with a similar issue, but it isn't just when cold and I don't hear static, just silence.  I could have a channel drop out at any time, but only at low volumes.  Crank it up, and the channel is back.  It's been going on for many years, and I had always assumed it meant the tubes in my preamp were near end of life.  But now I've replaced the tube preamp with a solid state, and the problem was still there.  So I've been using the CA-150 recently with the top off, and when it occurred today, I poked at a few components (with plastic of course) looking for a loose solder joint or whatever, and when I poked the right channel relay, it clicked back on!  So, I'm trying to locate new relays, although it may just be a solder/socket issue.  

It’s a cold solder joint.  Classe quality went downhill after Glen Grue took over from David Reich at Classe.  Your best bet is to have a tech go over every soldered connection. 

This problem is commonly caused by noisy differential input transistors. I've seen this on many solid state amps. As they warm up the noise often goes away. I really doubt a bad solder joint as the warmup issue would not exist.
