[MRCA] T-195

[B. Smith]

I have constructed several power supplies for the T-195  that run off of 
the AC mains  .   .   . In the event you can not find a "solid state" 
supply, you could use the existing low voltage section and construct a 
HV power supply.  But first you have to confirm that D601 the low 
voltage dynamotor is installed. And you need 28VDC.
D601  supplies  +250 volts, -45 volts(bias) and the elusive 115VA 400 
cycles for the tuning of the set.  -    -   -  IF, repeat IF D601  is 
installed most of the work is done in order to get the set on the air.


attch is a schematic of the power supply terminal section.
