Classe CA-201 Issue

Hey all,
I have a Classe CA-201 that is having an issue where half the time when I turn it on, I get a flashing green light instead of the normal red, indicating some sort of error. I had it in to a pretty reputable shop and they said they could not reproduce the error. I have it behind a big Furman power unit so I don't think it is an issue with insufficient supply or such.
Anyone have thoughts on possible problems I should be looking for that a shop might miss? Also, I am considering using this as an excuse to get something new (likely one of the new Pass Labs amps). I am not sure how to price this unit to sell it if I do that - any thoughts?

Thanks!
-Noah

I had a Classe CA-300 a while back and I had the flashing green light a few times including at turnon. It turned out this was due to some low-frequency pulses produced by the preamp while it was warming up. It would be easy to find out if your preamp is causing the problem. Simply remove the input cables from the amp and replace them with shorting plugs. If the amp doesn't have the blinking green light, then your problem lies with the preamp or source component. If you still have the blinking light, then you likely have a problem with the amp's internal circuitry.

I always thought it was strange to use green for the warning light and red for normal operation.
