Part needed

[Neil Morrison]

Have you tried a motor repair/rewinder shop?
Probably needs new bearings, and the commutator cleaned and undercut.
Usually, with small motors, by the time the brushes are gone, the rest is
needed too.

Regards,

Neil

Anyone got a clue where to find a motor, Heathkit part number 420-636, for
an SA-2500 Automatic Antenna Tuner?  I've tried to rebuild mine, but it
keeps burning up the brushes and shorting out.  Obviously, when it does
this, it's damaging the drive transistors as well.  This can get rather
expensive and rather exasperating...rather quickly.  Any assistance would be
greatly appreciated.  Thanks!
