Re: Crest repair center needed
While the details would help (maybe not me that much since I don't have a schematic handy), the "Hail Mary" reference sounds like a service tech trying to inject some humor to defuse an angry situation.
Shorting the output, as I mentioned in an earlier post, is something a healthy amp should handle easily and a broken amp, can proceed to finish failing.
If your amps are out of warranty you are responsible for the cost of the repair. In my estimation the "hail mary" troubleshooting, did not break your amp, It was already broken and the service tech was trying to help you troubleshoot the problem, and confirm it wasn't something simple.
It is common for power devices to fail as a short circuit and that often cause a cascade of failure as other parts connected to them also get compromised.
If you no longer trust your amps, that is understandable, customers get snake bit all the time. I suspect you can find somebody to take them off you hands.
Good luck.
