Phonograph motor fried??
#1

5/28/15  Hey Folks.   I am the process of restoring my third 53-1750 radio/phonograph.   Interestingly (and sadly) someone along the line had cut the power wires to the phonograph motor and spliced  the phonograph motor directly into the AC power cord  Icon_e_surprised .    I did a complete recap, replaced a couple of resistors.  Three of the original tubes were bad and they were replaced as well (all tubes now test ok).   I plugged in the set last night and it came to life - the dial light coming on, all tubes came on and it was receiving radio stations no problems.  However, when I flip the  selector switch to phonograph, the motor does not run.  I checked the resistance across the phonograph motor wire leads and get around 48 ohms.  I don't know if this is normal or if it means the motor is cooked.  I connected a voltmeter to the phonograph power wire leads coming from the set and my voltmeter reads ZERO (perhaps i'm not checking the voltage properly ?).     The radio/phonograph selector switch seems to work (or  atleast it switches to the am radio ok).  All connections from tube sockets to the am radio/phonograph switch seem to be ok - so I'm not sure if it is most likely that the phonograph motor is cooked OR the selector switch is fried  OR somehow, no voltage getting out to the motor.  Obviously, someone - way back when -  saw fit to splice the phonograph motor wires directly into the AC cord - so at some point, the phonograph motor had stopped working.  Any ideas?  Thanks.
