SONAR SRT-120

[Alan W. Fremmer]

Fellow Collectors/Restorers,
 
Any help in securing info/documentation on the above referenced transmitter 
 would be greatly appreciated.  It works, sort of.  Can hear the  
oscillator in a monitor receiver and the signal increases when the PA is  switched on 
but I can't dip the plate or increase loading.  Using a puny  power supply 
(300 volts) I'm seeing about 60-70 ma plate current.  Touching  the mic 
input I hear a definite hum in the receiver.  The tank coil(s) look  a bit 
stretched out and ragged.  Any recommendations to bring the old lady  back to 
full functioning would be quickly acted on.  Thanks, in advance,  for all your 
help.
