Hi, all concerned:

This one was on ebay a while ago.  Bids didn't get past the reserve, and I 
made an after-auction offer which was accepted.

There was no information on what is inside.

I've gotten as far as turning it on, listening on 40M, and documenting the 
tube lineup.

Its general form is:

6AK5-6JH8-6JH8-6BJ6 X3-6AQ5, with l-o's, bfo, detectors, agc-amps, S-meter 
circuitry.  The r-f stage has separate peaking.  The 1st-lo is tuned by a 
smooooooth National PW-type drive The second i-f has provisions for 2 
switched 9-pin plug-in-style mechanical filters and a "wide" position. 
 Sri -- the filters are long gone.   Power supply is internal, with a couple 
of 0B2's.  Line cord has one of those fused plugs which purist-collectors 
drool over.   I don't have a pic of the bottom side; howevewr, it's nicely 
homebrewed.

Date codes on the tubes are '50s and '60s.  All but two of the shields are 
those nice ones with  dissipators inside.

There are 5-pin plug-in coils for 80-10M, and extra BUD ceramic forms, in a 
box.

Physically, it is H9"XW12" with tilt built in to the design, and 18" deep. 
It weighs around 30 lb.

I have the ebay jpg's, which, if I knew how to make into binaries, I could 
post on alt.binaries.pictures.radio .   They can be emailed to interested 
parties.

My original intent was to find an "HBT-XX" homebrew transmitter to go with 
it, and the intent has fallen by the wayside.   Oh, well . . .

So . . . take advantage of my indolence.  Make me an offer I can't refuse. 
Include about $40 for insured-ground shipping to conus.

73, and tks for reading.
