I gave the amp to someone who knows more than I do, he's going to troubleshoot it and try to fix it. If he can't, I'll make a new thread with all the details and what he found during troubleshooting. Hopefully he can fix it, high powered Class A amps are way too hard to find. If someone made a decent 100wpc class A amplifier for a good price ($1500 is realistic), they'd get rich!
