with a number of unoriginal holes filled in. The paint
job was done with Krylon and is a bit heavy. But the
overall look of the radio is pretty good. The speaker
was re coned by Jackson speaker service. I restored
the power supply and it is working as designed. The
receiver itself has not been touched and is untested.

photocopied miscellaneous HRO documentation. This has
the factory-installed noise limiter. This is a really
clean, original HRO. $595

“Globe King 500”-based Homebrew Transmitter. This is a
homebrew transmitter in a 5 foot tall rack. It has 5
decks in the rack: 500B on top, speech amp, modulator,
modulator supply and RF deck supply. The key to this
transmitter is the stock WRL 500B RF deck
(bandswitching 160-10 meters). The rest of the rig is
homebrew. But the circuit very closely follows the
rest of the WRL 500B transmiter. The modulation
transformer is a Thordarson 300W Multi-match. With
3B28’s in the power supplies. Rack has been repainted
and looks great with stainless steel rack hardware.
The mod deck has a cool windowed panel with a door
that opens to allow access. Electrically, the
transmitter is in good shape and working--I’ve had it
on 80 meters. It sounds very good. I started to re-do
the AC wiring to the various decks and it is done, but
still needs some tweaks (like power switching!). The
modulator deck had a bad KV meter on it. I have a
replacement meter for it, but you need to build the
correct multiplier resistor to go with it. But you
don’t need that meter to operate--in fact, you could
just eliminate the meter. The only other thing that
you may want to add is a T/R relay. The 500B RF deck
has a good, strong 4-400A in it instead of the
WRL-specified 4-250. The 4-400A is loafing. The speech
amp section has been re-done and now sports a
comnpressor that can be switched in or out. With
original WRL Globe King 500B manual and some builder’s
handwritten notes. Pick-Up only in Pittsburgh, PA.

Hallicrafters SX 28 receiver with matching speaker.
This is in very pretty cosmetic condition. I took a
front panel from a hamfest radio, chose the best knobs
from 3 duifferent sets, polished and shned it all and
it is eye-ctaching. The cabinet has a couple small bad
spots but is also excellent. This was working 2 years
ago. It would probably come up okay on a variac but I
cannopt guarantee that. With original manual and
original military TM 11-874 military manual for
AN/GRR-2.. Also have many restoration notes taken off
of the web. The matching speaker is the one with the
lowewr case “h” and it looks very good, though it has
some surface paint scratches on top. $575

Heathkit SB-620 Scanalyzer. 1967-vintage panadpter
matches the Heathkit SB-301. This looks very good or
excellent. It is working but does not display a signal
from my SB-301. The IF is supposedly wired for 3395KC
for SB-301 but no signal and I didn’t ever debug the
problem. With original manual. $120

and is working but speed pot is physically broken and
sidetone volume pot doesn't do anything. With original
manual. $40. They were bought by MFJ and this unit was
sold for years under the MFJ brand name. Originally
made by George Risk Industries.

Curtis KB-4200  Morse Keyboard. This is the
grand-daddy of them all. It’s 1974-vintage and I
believe it is the first commercial morse Keyboard. The
later more keyboards all started out using the Curtis
chip set. Selectable speed, buffer memory, etc. Looks
great. It appears to work, but I can’t get it to play
a sidetone. With original sales brochure--I was never
able to find the manual. I beliebe these are rare. I
have never seen another one on the Internet or
elsewhere. $99
