Hey there. I ordered from GC a Trace Elliot AH600SMX advertised as in good working condition. I got a steal on it because they actually had it listed as AH400. I got it to our room and plugged it in. I get the power light in the back on and hear the fan but have no lights or power on the front of the amp (not even the black light). Only guy I know that repairs amps is 6 weeks out. Could a connection have jarred loose during shipping? A possible easy fix? Suggestions most welcome
