[R-390] What about this one

[William J. Neill]

Applicable technical manual is;

NAVAIR 16-30ARR-41-50

My copy is dated April 15, 1956, and I can't find the thing.

I couldn't find much information on the R-648/ARR-41 but I did find a  
tube
line-up.

They seem to be all the familiar R-390A high voltage tubes rather  
than the
28-volt tubes used in the R-392.

Also, from what I could tell the only voltage required by the R-648  
is 24-28
V dc.

There seems to be a whacking great power transformer on the right  
hand side
of the
chassis. Does it have an internal dc power supply? Vibrator? Solid- 
state? Or
am I missing a 400 Hz power source connection?
