[Boatanchors] T-195 spare parts

[James Duffer]

I vaguely remember that placing a dc (small value) on the input to the 
chopper of the servo amp circuit would activate the servo motor, reversing 
the polarity would cause the motor rotate in the opposite direction.  I also 
remember on the older dynatomotors/alternators the 400 Hz was created using 
a permantent magnet in the alternator, you could if you were careless 
measuring around the windings of the servo, there was one winding which had 
DC (B plus that was supplied to the servo amp output tube) and if you 
shorted with your probe to the other winding which was the output of the 
dynamotor/alternator you would inadvertently de-magnetize the magnet and the 
400 HZ output from the LV dynamotor would be very low making the servo 
system inoperative.

I had 14 T-195's assigned to me while stationed in Lenggries, Germany (they 
were part of the AN\GRC-46.
