Your first mistake was leaving the anode connector off as that does
absolutely nothing for burn in. Dont blame the wife (-;
Your best bet is to get someone familiar with amps to start tracing the
circuits, it could be something as simple as the On-Off switch.
Its an easy amp to work on, I get them in here regularly for repair.
