Ralph,

Don't go out of your way to get the autotune power supply, unless
completeness is your passion.

That supply ran four 391's with one large transformer and selenium
rectifier. Output was 28 volts at 24 amps, IIRC. Don't think there
was a filter capacitor. The power only went to the motor, through
a marvelous switching system.

As Roy Morgan said, don't even think about tearing up all of those
pot metal castings until you can turn the shaft by hand, or maybe
with a six volt battery. An old, dirty receiver probably has oil
and grease that is no longer slippery. Best to clean and relube.

Ah, but don't take apart the stacks of sliding stops if you can
help it. Complex reassembly. And don't lubricate the clutches.
They are supposed to work by friction (or is that the 389?).

If everything turns smoothly as is, you may have a radio that didn't
work and wasn't used.

The MC and KC knobs do have the locking screws in the center, right?

I wish you a cheery Good Luck. You should know that saying that does
not help you, it only makes me feel better.

Greetings to the list.
I subscribed to this reflector about a month ago and have found it to be
quite interesting and fresh. The reason for signing up was to see if
this was the correct reflector that might be discussing the R-391. I
looked for a reflector on the list but found none. I have a R-391,
serial # 105. Along with it I have a Crosley Loudspeaker assy. LS205-A
and a Signal Corp Standard Oscillator, TS39B. They all seem to be
complete, except for the powersupply for the R-391 autotuner. All are
very dirty but not all dented up ect.

Is this the place??? Thanks for your time and interesting comments.
Best Regards,
