Radio Equipment for Sale

Ordering information:All items are subject to prior sale, so inquire first as to availability. Please provide your address so I can check shipping of heavy items. Click here to email us.

Condition: This equipment comes from flea markets, hamfests and estates, and unless otherwise stated they are complete, appear to be in good condition, but are unused and untested by me. Since tube condition (if used) is unknown, and such items as electrolytic and paper capacitors degrade with age and switch contacts oxidize, you should assume the equipment needs testing and possible repair before placing in service. In other words, unless otherwise stated, all items are offered untested and as found.

#SOLDER .015 and .020 Kester Solder.

One pound rolls of Kester "organic core" solder, 63% tin, 37% lead.
I believe "organic core" means rosin flux-core solder but I can't guarantee that. It should be good for radio and electronic work. I have one NOS roll of .015 solder, and one roll of .020 solder.

$14.95 per roll (Specify which diameter). (s/h = $7.50 for one roll; s/h for two rolls = $8.95)

#408SOLDER Kester 3/32" Solder.

One pound roll of Kester 3/32" rosin core solder, 40% tin, 60% lead.
Meets federal spec. QQ-S-571b.

$14.95 (s/h = $7.50 for one roll; s/h for two rolls = $8.95)

Signal Corps WWI trench transmitter

This is a Signal Corps portable spark transmitter marked SCR-74-A, made by American Radio and Research Corporation (AMRAD), New York NY and Medford Mass. (Reference BC-18A.) It has the instructions and schematic in the lid, and an original paper tag attached (not filled out) with AMRAD's Medford Hillside address. This consists of an induction coil, spark gap, battery meter and telegraph key. The large terminals on the left marked ANT and GND and are for attaching the antenna and ground to the set. The compartment on the right is for the 10 volt battery. There is a rubber cover so that the telegraph key can be operated with the lid closed, and two mica windows in the lid for observing the spark gap and the amp meter.

This military wireless set was designed for reporting from the trenches as described by Capt. A.P. Corcoran, "Wireless in the Trenches," in Popular Science, May 1917, pages 795-799: "The wireless, as I have said, is now an essential part in all trench warfare. When the infantry adavances to an attack, the operator is always slightly to the rear. Where formerly a detachment of men had to reel out hundreds upon hundreds of yards of cable to establish telephone communication between a trench newly taken from the enemy and the first line reserve behind, now the operator simply picks up his box, his ground mat and his aerial singlehanded and advances simultaneously with the attackers. Arriving at his new position, he props up his aerial, lays his ground mat and communications are established almost at once. It would be hard to overestimate the importance of his duties. When an enemy trench is being taken, it is he who reports the progress of the encounter-- the number of the enemy, the nature of their defence, the amount of the casualties on either side, the condition of the trench when it is finally taken-- whether it has been badly damaged by artillery fire, or whether it is practically intact. If a gas attack is coming, it is he who sends the warning to the men behind to put their gas helmets on."

This particular set was probably made after the end of the war, around 1920 or so. It appears original and complete and in good condition, with the exceptions that there is no battery and the web carry strap is broken. The case is about 11-1/2 x 12 x 6 inches. It weighs 20 pounds. A scarce addition to your early wireless or military radio collection.

#L1006COE Leach Break-in Relay.

Model 18 type S-1. The wireless radio break-in relay was invented by Val Leach in 1919. When sending (with a key), the relay controlled the power contacts and also switched the antenna to "receive" between dots and dashes; thus one could listen in while sending and permit the other party to "break in."
This early model has the San Francisco address, and so dates before 1929. The heavy Bakelite base is 4 x 5 inches, and 3/8" thick. The main contacts are a huge 5/8" diameter. This is in very good condition. The coils test good with an ohmmeter. Larger photo
Also see this flyer for more information.
$97.00 (S&H = $8.00)

#NFM-07 National NBFM adapter.

This is a narrow band frequency modulation adapter for the National Company HRO-7 receiver. It has a 6SK7 tube and a 6H6 tube. It plugs directly into the accessory socket at the back of the receiver, and is held in place with an existing receiver screw holding the bracket. On the bottom is stamped the make and model of this item. There are a few small spots of light oxidation on the bottom, otherwise this is cosmetically very nice. $129. (S&H = $8.00)

#HWMETER Harvey-Wells Bandmaster meter.

This is an original Grid - plate current panel meter for the famed mid-1950s Harvey-Wells Bandmaster transmitter. It fits a round, 2-1/4" hole and has two scales: 0 - 10 and 0 - 200 ma. Very good condition. $24.00 (S&H = $5.00)

#HD19 Heathkit Phone Patch.

Heathkit model HD-19 hybrid phone patch, with manual. This item from 1960 was used to transfer audio signals between telephone lines and radio communications equipment. This is in very good cosmetic condition and includes the original manual (also very good condition) that describes assembly, installation and operation. $24.00 (US shipping = $10.00)

#1104TTL Spark coil with interrupter.

Here is a rarely-found wireless (spark) coil and interrupter contact assembly. It includes the usual capacitor (called a condenser in those days) below decks - see the second photo. The coil and interrupter are mounted on what appears to be an asbestos plate, with the condenser between the plate and the bottom wood base. There is no maker's name to be found; this may be a home-assembled item. The coil seems to be good at 500 ohms, but the operating condition of the assembly is unknown. Coil-interrupter sets are quite scarce; this is offered as a vintage display item. Photo 2 $245. (UPS ground S&H = $12.00)

#WS19A WS 19 Headset, microphone and mike holder.

For the WWII era Wireless Set no. 19 -- microphone (marked "microphone hand no. 7" and with red "RS-8" stamp), and headset, complete with cord terminated in 5-contact connector, together with chest mike mount with straps. Both the mike and headset each have a small unreadable red stamp. Note, a collector believes this equipment was intended for the Russian radios post-WWII. This was found in a box of new old stock spares. Appears to be in very good unused condition. The cable that connects the headphones, mike and connector is like new. The headband and strap on the 'phones looks new, as does the chest mike holder and its straps. The only fault I find is that the rubber on the mike mouthpiece is cracked from age.

#RWSA804 Wireless Specialty Apparatus Co. variable condenser.

This unusual RCA/Faradon condenser was made by Wireless Specialty Apparatus Co. It it unmarked, but looks like the model UC-1831 or 1819. The entire 4" diameter round part rotates, and it works (I am told) by the pressure of the "liquid metal" (buyer assumes all responsibility, if you get my drift) on interior plates. The black knob with metal skirt may not be original. Also included is a fixed Faradon model T .001 Mfd condenser, which carries the WSA name and six patent dates from 1919 to 1924.

#900 James Millen W1HRX QCWA pin.

The late James Millen is best known for his work on the National Company SW-5, 4 and 3 short-wave radios and that classic collectible, the HRO receiver. The products made later by the James Millen Manufacturing Company, including the 807 transmitter, the vari-arm VFO, the grid dip meter, and others, are still eagerly sought by collectors. It is not often that I can offer something not merely rare, but unique -- and here it is: Millen's personal membership pin for the Quarter Century Wireless Association. If you are a serious "Millen collector," you will understand its importance. The actual size is 1" across. $495. postpaid.

Tower ship speaker.

An old, rare cone speaker. The frame is cast iron; the circle is 17.5" in diameter, and the overall height is 18". Needs restoration: The paper cone is gone, the painted finish is stained, the coil tests good. This is one of the most impressive cone speakers you could add to your display.
