Just picked up a Panasonic PV-1730 Hi-Fi VCR

Since you have the Sam's, have you verified that the voltages from the power supply are correct?

I did check the voltages and the seemed to be where they were supposed to be. I did notice though in the Sam's that there is a Voltage regulator transistor for the supply reel motor which (which seems to be the only part of the motor drive board that has a voltage regulator transistor), I wonder if that might of failed and that's what's causing the supply reel motor to malfunction, either that or some bad capacitors on another board somewhere in the VCR.

Also I was looking at the Servo/Control Board for this VCR in the Sam's and it seems that it does indeed control the take-up and supply reel motors as well besides the capstan and drum motors.
So again I think I might take a look at that board for some bad capacitors with my ESR meter.
