Re: Help with motorboating?
Pump,  
Wild Bill is on it! I'd also add that the location of the decoupling cap for the first gain stage may need to be changed. Grounding locations can cause motorboating as well as ground loop hum. FWIW. The last amp I built is totally star grounded to a single point next the OT. This worked wonders.
