Getting closer. I completely cleaned and lubed the bearings of two command receiver dynamotors and get overpowering dynamotor noise in the audio. All three receivers have new caps and work just fine with an outboard power supply with 24 V AC on the LV and 60 VDC on the HV when not plugged into the rack. Would this be a strong sign that the original chassis wiring in the receivers definitely needs replacement?
