[Milsurplus] [ARC5] AN/ARC-60 to 220?

[Jack Antonio]

It was a  rainy day in Georgia,
(maybe it will be a dark and stormy night as well)
so I worked on the CV-431 I mentioned earlier.

As it turns out, what I have is a CV-431A,
which is somewhat different than the CV-431.
Control and power connections are the same,
but the A version has a different tube line
up, using a 6939 and a 6360.

Fired it up, and it works. Too well in fact.
Puts out 1.4W at full B+ with 125mA current
draw. Since the receiver dynamotor supplies
the B+ and it is only an 80mA unit, this
doesn't sound healthy. If I lower the B+ to
175V, I get .5W at 76mA, which seems to be
right.

So, anyone have a schematic for the CV-431A?
And hopefully a system diagram, as I'd like
to see how B+ was distributed.

Was there an A version of the AN/ARC-60? I
have the books for both the Type 12 and the
AN/ARC-60, but neither one mentions the CV-431A.

Thanks
