[R-390] Diagnostic Help Needed (Part 2)

[bavarianradio at comcast.net]

Hi Joe,
  It sounds like the PTO shaft may not be turning. Take a look at the oldham coupler which transfers torque from the KC tuning knob to the PTO. make sure the setscrews are tight and the center piece is there and working. I had a similar problem with my 392 a year or so ago. GOOD LUCK! Ross
