[TechAssist] Re: Thorens TD126II Turntable schematic

Hi,
The motor, belt, flywheel are all very free as they should be. Settings are
correct for 110 volt mains.
I believe this is an electronic drive problem, when the voltage is applied
before the
fuse eventually does blow, the motor has a cogging effect if you try to turn
it by hand.
Looks like very involved electronics to me, without a schematic I don't want
to delve into it.
