The whole thing except the power supply is currently in an ex-Altec dark green desktop rack cabinet. Thie radio has been repainted 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. The s-mater glass is missing and the meter vane needs straightened but the meter works. I restored the power supply and it is working as designed. The receiver itself has not been touched and is untested. With original of newer HRO manual and Photocopy of older style. $435

This has the factory-installed noise limiter. This is a really clean, original HRO. $555
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.

This looks very good 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 Originally made by George Risk Industries.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
HH Smith Code Practice Oscillator/Monitor. Tube type in the steel cabinet. $5
Plain “ham” straight key on thick lead and plastic base. Nice. $20
Lafayette TE-25 C-R Analyzer with original manual. This has transformer ratio measurement capability. Untested. $45

Military Navy WWII RBB-2 and RBC-1 Receivers. These are WWII Navy shipboard radios covering 0.5-4mc and 4-30mc respectively. Made by RCA dream team. With one matching power supply, 2 cables to go from supply to radios and original AC power cable. With original RBB and RBC manuals 
and copy of Coupling Kit CN-10563 manual for panadaptor (not included). Both radios and the supply are in very sharp original condition, with all internal covers and all tubes uncluding the goofy ballast tube. Cosmetically, these are very good with some paint chipping around the panel edges and small scrapes here and there. The knobs are somewhat faded. Both the cabinets and the radios have their original tags and the cabinet s/n’s match the radio s/n’s. I have a bunch of spare metal tubes to go with these and a few odds and ends spare parts. $849 for everything. I would separate them for an excellent offer. Prefer pickup in Pittsburgh PA but I will ship them for the actual shipping cost. Shipping may take as long as 20 days due to my busy schedule.
GWE III AM Transmitter. This is in a 5 foot wooden rack--very pretty with many matching meters. It uses plug-in coils and puts about about 120 watts. This seemed to be working perfectly when I bought it but then discovered a strong parasitic in the exciter. This was fixed and the TX tests out good on 40 meters. No other bands were tested. Needs AC power rewired using 3-conductor grounded line. It could also use new HV connectors for safety. It was all built and/or modified by N3GWE, Ed Mantick. It was purchased by me in September, 2002 after Ed needed to sell it due to the onset of health problems.
Final: 812
Exciter: 6AG7’s driving 807s
Modulator: 45s driving 809s
Power Supplies: Solid State.
N3GWE Modified Eico 722 VFO notes: Modifications include 6AH6 in place of 6AU6 and power supply changed to full wave rectifier using a better transformer. Repainted nicely with black case. Looks good. Knobs are not original. Working perfectly and quite stable after 20 minutes. 
--Ed’s original documentation goes with it. This uses Ed’s modified Eico 722 VFO. This rig uses plug-in coils and a full set is included. Asking: $425 with coils and modified Eico 722
Thanks for looking.
