[Milsurplus] solid state dynamotor

[Lloyd KK7IZ]

One long overlooked source is the old Narco Mark 12 power supply modulators, 
T-12MP12 ,12A, 12B.
They provide a high voltage PS capable of handling a multi-tube receiver, a 
5763 transmitter and associated stages, a modulator good for a conservitave 
10 watts and a speaker amp same power. For a number of years aircraft radios 
were hybrid, tubes and transistors. Have never seen anyone take advantage of 
the parts in them.

Anyone have a DC to DC inverter or solid state dynamotor replacement? Was 
thinking of building up a replacement power supply deck for my ARR-41 I am 
going to remove the original dynamotor deck and set it aside in case I want 
to use it but want to build a solid state replacement deck that will fit 
into the original radio and allow it to operate without the noise of the 
dynamotor deck. Do not want to change any of the DC distribution wiring so 
would prefer to use something like the solid state replacement dynamotors 
that were used on some of the last produced ARC equipment, also if anyone 
has a hacked ARR-41 power supply deck less dynamotor that will save a lot of 
fabrication.
