Portable Panasonic Record Player

This is probably a long shot, but does anyone have a dc motor model MHE-5D? I want to try a new motor. Here is the problem. The motor has almost no torque. So, when playing a record it will slow down even slower than it is running. There is a voltage regulator board under the platter. I had recapped the power supply, amp, and replaced the one cap on the regulator board but still the voltage was to low to the motor. Without the motor connected all the voltages on the regulator board are normal. As soon as the motor is connected all the voltages on the board are lowered. It drags the supply voltage down from 10V down to 4 to 6 volts. Only with the motor connected. I have cleaned and relubricated the changer and that is not the problem. The idler is in good condition. It is not slipping, it just cant supply the right current when I connect that motor. It is running it at 3.64 volts. 3.64 volts is correct, however,The motor is spec at 6 to 9.5 volts. The motor runs, but just barely touching it will make it stop. Any ideas, or anyone with a new motor I could buy?

Thanks
