Phase adjustment on Teletype motor?



Original poster: "John Richardson" <jprich-at-up-dot-net> 

Hello,

Has anyone used the old 1/20 hp Teletype motors, the ones with a start 
capacitor mounted on the bottom of the motor frame, with John F's phase 
controller?  I read in the archives that some of these motors didn't 
require a capacitor in the phase circuit, just a variac.  How true is 
this?  If anyone has built this circuit with this particular motor, please 
let me know what value, if any, you are running.  I did order some 370 volt 
run caps, both 65 and 25uF, so hopefully I can mix and match and get a 
working value.  I have been running just the NST across the rotary gap, and 
playing with the rotary variac trying to get the electrodes to fire, but no 
luck yet.  Seems to me that I should be able to adjust the phase of the 
SRSG to get the rotary to fire with just the NST, to let me know that my 
phase is changing.  Info appreciated.

Thanks,
John Richardson
