Is may be possible then board follow MK3 component pattern from 1989 ?
In any case is not error from worker on sake
Yes, I think so, the board is marked '88, but looking at the service manual of the M3D,
it are exactly those values.

Such component in area of filter amplifier part of IC is concern with the noise control
plus the hysteresis control of circuit.
Isn't the hysteresis control the most important part to obtain best speed stability under dynamic load???

Torque for such motor type is set by mechanical construction concerning number of poles and such like.
If looking for any torque control from component change then look to current delivery control elsewhere.
I never mentioned wanting to change torque.
I hope the Technics engineers chose te right balance between torque, rotating platter mass and bearing friction.
If the torque was really too low, the table would not exactly be under control, the whole purpose of direct drive.
Is it possible to increase the torque without damaging the motor???
