I managed to get the motorboating stopped. Everything now seems to be functioning properly except the oscillator section. If anyone has any suggestions on how to properly troubleshoot that section, please let me know. Both the oscillator and mixer tubes (XXL's) have been checked, and filament and plate voltages are normal. Looks like I'm going to have to tackle the dreaded four section, ganged switch. Suggestions?
