sony tc-500

[lectec]

hoping someone can help.

i repair stereos for a meger living but i am not familiar with this unit. the sony tc-500 is a dated reel to reel with vacuum tube power.

problem: the capstan motor will not accept any torque. it stops immediatley. normally i would suspect the motor. however, there is a capacitor that taps into the motor to ground. my limited understanding of this is that is a (starter?) capacitor. i dont know what kind of voltage i am suppose to find here. i have the schematic but it doesnt say.

can anyone explain the theory to me.

thank you
