Default Re: Help getting Motor to Run on TK20

Guys I finally had success and I am not sure what the issue what. I replaced the main fuse to start with as it was corroded but that was not the issue. I also had some suspicion on connections of the fuse holder and the voltage tappings screw, however the problem seemed to be trying to operate the machine upright. By trial and error I helped the motor to start at around 140v and it kind of kicked itself into motion, and it seems to be that flywheel was causing friction against the head plate as it sounded like a grinding machine. Pushing down the capstan shaft cleared the issue of that horrendous noise and now the motor is running gently for few hours on the variac. Thanks for your help once again. C
