[NJARC] Turntable question

Mon, 29 Apr 2002 09:58:16 -0400

Rob,
  The only turntable motors I have seen that run at a lower voltage are
installed in very cheap portable phonos. They put the motor in series
with the one tube amplifier filament. I've never seen this arrangement =
in
a console so it is a very good bet that it runs at line voltage.

Phil, our resident 45 expert should be answering this, but typically, =
any
turntable motor I have seen runs off the line voltage.  You should be =
able to
easily trace the wiring back through the plug (assuming it has one to =
connect
to the radio chassis) and to it's source in the radio chassis.  You =
could
also measure the voltage at the connector on the chassis if you wanted =
to be
100% sure.

Some of the better or more expensive turntables have a speed control on
them.  I haven't had any experience with them so I don't know if it's
electric control or mechanical.  The early victor motors (20's and early
30's) have an adjustable governor controlled motor.  Either way, it =
would be
located on the turntable and you should still be able to connect power
directly to the turntable connector.
