Ayre preamp no output


Any answers on why my Ayre preamp quit giving any output signal to my amp after power company switched my meter. This would have turned off and back on my power to house. I can hook my OPPO BDP 105d direct to amp and everything plays fine. When hooking OPPO to preamp and preamp to amp nothing. All the lights and volume goes up and down on the preamp, but zero signal being sent to the amp.

I guess it is like shutting the stable door AFTER the horse has bolted but maybe you should have had everything powered down and unplugged BEFORE the electric utility company went to work on your supply......
Uberwaltz... had I known they were coming I would have done that, but the thing is there was no notice, letter or call they were coming around changing meters. I was at work and not home and came home to a flyer on my door what they did. Really kinda bothers me they did this without notice. 
Just curious if any surge protection device was in place when
you were done in by the power play?
