I experienced a similar problem with a CA 100.
These amps are getting old so it could be a bad cap or even a bad solder joint somewhere. (The cost of repair could approach the price of a replacement amp, but then you don't know if the replacement might be close to developing a similar problem.)
Or, could you just leave it "On" and avoid the cold start problem?
I have had poor success with Classe repair for products manufactured prior to the acquisition. Factory support for these older lines seems quite inconsistent.
