Just added vintage radio crystals and detectors near bottom of this page.

Westinghouse Aeriola Jr. Crystal Radio Set circa 1921-1922

This is an original Westinghouse Aeriola Jr. Crystal radio set in good condition, with the original Perikon detector, and all the original binding posts. Cabinet is in great condition, appears it may have been refinished some time in the past. The label is in such good condition that I wonder if it is a reproduction. In any case, a great looking Aeriola Jr. crystal radio set. $324

Rayflex 1920's crystal radio

This is a factory made early 1920's Rayflex Batteryless Crystal Radio set. Interior looks pristine exterior has mild finish wear and one corner chip but overall looks reasonably good. $139 

Crystal Radio built in Aeriola Jr. Box
This is a nice early 1920's crystal radio set in an Aeriola Jr. box, possibly using the Aeriola Jr. variometer and front panel as well, so that only the binding posts, knob, and crystal detector are non-original to the Aeriola Jr. Looks like it has an ERLA style detector. $149

Reproduction Crystal Detector with catwhisker and mineral selection

Click photo for a larger view.
Nice reproduction of 1920's style detector on a 2"x2" solid oak base. Features a large 5/8" diameter brass ball-and-sleeve assembly in a tight, spring brass bracket that never comes loose, or needs realigning. Precision ball-and-sleeve provides silky smooth movement with no pull or backlash. Includes a selection of loose minerals., catwhisker wire, printed instructions, and a history of the mineral detector. $24.95 plus shipping. These are available directly from the manufacturer, Larry Pizella, but I don't have anymore is stock, so just click HERE to see the order page for detectors directly from the maker.


Simple Loose Coupled Crystal Radio with Headphones #4

This is a simple little crystal set made on a nicely finished breadboard type plaque, has a 2 circuit loose coupled circuit, with a diode, variable capacitor with dial knob, and Fahnstock clips for the antenna, ground and headphone connections. Complete with Cannon Alnico 1000 ohm high impedance single sided headphones. Just hook up antenna and ground and it picks up loads of AM stations here. $39SOLD LD

One Tube Shortwave Regenerative Radio Kit with Submini Tube.

This is a kit of parts to make a one tube regenerative shortwave radio based on a 6418 subminiature tube. It includes all the parts needed to make the radio as shown above, with vintage National porcelain tuning condenser new old stock in original box, Johnson trimmer capacitor, ferrite toroid coil core, breadboard, and all necessary electronic components, hardware, wire, and a pair of Newcomb high impedance headphones. There is a set of detailed instructions, plus schematic and diagrammatic sketches to aid construction. I have enough parts for 4 sets right now, may be some variation in the knobs available. $49SOLD OUT
  Inquire if interested and I should be able to put together the parts for another kit but am out of the variable capacitors now, can provide the submini 6418 tubes for $2.50 each, also have some other submini tubes that would work.

Below is a photo of a completed set, using slightly different parts. The frequency range as tested was 5.5-9 MHz, but the coil can be modified to other frequencies.
