Hello Danny & the group,
I did a FEDLOG search and did not turn up any part numbers showing this
Ballast (2HTF11B) .
I've seen a lot of ballast tubes and this number eludes me. I wonder if
this was a DECOY UNIT to throw our adversaries off track??? Did you or do
you have a picture of the IF Unit to post for furthur
insight and corroboration by the group experts?

Subject: [R-390] Preproduction R-390
This is my first message to the group. I have been a subscriber and have
been reading messages for some time. I went to a hamfest last Sunday and
bought what I thought was an ordinary R-390 (non-A) receiver. The only
thing that was out of the ordinary was the serial number- "PP-2". When I
got home with the unit I noticed a poorly stenciled notice on the side. I
cannot make out every word in it, but it sounds like this is a
"Preproduction" R-390". Here is the what is stenciled on the side except
for the few words that are illegible. "This equipment was tested as a
preproduction sample by the Signal Corps Engineering Laboratories. It is ??
???? intact without alteration or improvement of any kind for use by the
Signal Corps ???? by ???." The question marks indicate words I cannot make
out. The order number is 14214-PH-51-93 and was manufactured by Collins
Radio Company. The ballast tube, V-512, is marked 2HTF11B and is missing.
The front panel lettering is punched, not silkscreened. The power supply
has a nomenclature tag with the serial number PP-7 stamped on it.
Can anyone give me any more information on this radio? I would appreciate
it.
Thank-you,
Dan
