Hello again,

Thanks to Chuck for suggesting the LM-324 IC being bad, as that was the
problem.

Hello all,

I've got a Thorens TD-180 turntable with a runaway speed condition.
Usually, this is caused by the lamp that shines on the photo cell going
bad, but not here. There are pulses coming out of the photo cell, and
the lamp works.

I've tried contacting both the US distributor to order a shop manual,
and I've e-mailed Thorens in Switzerland to no avail, and its been
months. Does anyone have a schematic that I could get a photocopy of?
Any other suggestions would be welcomed too.
