I have a Thorens TD-146 turntable whose motor doesn't turn. It's being
fed by a new 16 VAC/300 mA wall wart.
Anyone know what typically goes wrong with these? Anyone have
schematics?
From looking at the PCB, it seems to have a full wave rectifier circuit,
one transistor (with no identification), an LM324, an MC34001 and
miscellaneous passive parts (caps and resistors).
What kind of waveform drives the motor's four terminals?
The LM324 often fails on this model. chuck
