[78-L] Technics 1200 Goin' Bonkers

Martin,

	Are you saying the turntable rotates clockwise then reverses and
rotates counter-clockwise, then repeats?  If so, I seriously doubt it is a
bad bearing.  I would suspect the power supply.  It sounds as if the direct
drive DC motor is receiving AC through a faulty Capacitor, bridge rectifier,
or switching power supply circuit.

Tim

Hi Guys,

Can't remember if this has been discussed before.  I've got one of those
Diapason modified turntables that recently developed a problem.  The platter
just shifts directions instead of rotating.  At first the speed went random
and now it looks like a bird turning its head.  Any ideas?

Martin
