Any idea what transmitter this is?

This transmitter is over on the Ebay links section...

Does anybody have any idea what this is? The seller really doesn't and doesn't seem to have access to the unit at the moment due to divorce proceedings.

I'm tempted to go for it since it's not that far from my QTH.

Any ideas?

Looks homebrew to me. Navy rigs were all black wrinkle until sometime around the Korean War when they started using gray, even went so far as to repaint rigs like RBBs, TDQs etc. The photos aren't terribly clear, but it seems to lack the typical mil tags and control labeling as well.

Probably a very well made unit though by the looks. Certainly worth snagging for that price if it's close to you, regardless.

That's what I figured, luckily I have a very tolerant wife!

It's about a three hour drive down there and I have a friend to visit in Cedar Rapids anyhow.

I'm hoping to get some more info from the guy too.

I'll probably have to clean up a little mercury contamination too, since it sounds like the two tubes behind the windows on the bottom rack got broken, probably 866s!

Now all I have to do is finish the shack and get the heavy metal moved in!

divorces. non understanding people (like the X-XYL getting the yard workers to slide it down the stairs when the OM was out??) nuts. well, Looks like a nice piece, pls. post lots of pictures of the recovery and inspection once you get it home.

I second the HB vote, which in my eyes is much better than just another johnson or heathkit anyways.

From the new pictures I've seen it definitely isn't military, but it may be a circuit copy of a BC-610. It looks like a 250th modulated by a pair of 100ths which seem to be driven by another 100th. Big open frame plate transformer and big mod trans too. Power and bias on the bottom followed by modulator deck, exciter deck and the PA deck on top. It looks like it may have gotten damp on the bottom of the rack which looks good in front and rusty in the back.

His father maintained that it was military, but it clearly wasn't built that way. I suspect that it was built by his father or one of his friends based on a military rig. He has a whole folder of stuff including wire call outs for the different decks and schematics.

At least if it uses a 100th instead of a pair of 2A3s for the audio driver I won't have to compete with the audiophools for tubes.

If I get it I'll document everything.

The grey panels in the black rack suggest that it might be an assemblage of some mil decks from perhaps different units plus  maybe some HB racks to make the final piece. Either way, I'd grab it if I were close enough.

There are no eye bolts visible. It can't be a Navy TX.

but I do see chocks and cleats...

The various MARS programs gave lots of us access to loads of parts to build with in the 50-60's.

I joined AF MARS at Mitchell Field (LI, NY) and collected enough BC-610 and other parts to build a PP 250TH amp with 810 modulators while still in HS.
