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. $350

Aeriola Senior One Tube Radio set up

This is a good working Westinghouse Aeriola Sr. radio that comes complete with a pair of Brandes headphones from the same year (1921-1922) as the radio, battery holders, a good 1920's genuine WD-11 tube, and wire to use for antenna and ground. The radio has the original instruction sheet. I have played the radio and picked up at least 2 dozen stations packed across the dial.  $199

Aeriola Senior one tube radio

This is a working Aeriola Senior radio in reasonably good condition. The wood case has some scuffs, the paper tag is a replacement, and the original WD-11 tube socket has been replaced with a standard 4 pin socket and I put in a brand new Hytron 864 tube and the radio plays great with stations packed across the dial. You do have to unscrew the 4 panel screws and lift the chassis out to replace the tube, but it should last for several hundred hours of play time. It runs on a 1.5 volt D battery for the filament voltage, and three 9 volt batteries in series to provide the B+ voltage. You will need to provide and connect antenna and ground wires, high impedance headphones, and batteries to get it operating. Sale includes radio and the tube. $99

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. $179

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

KR Crystal Radio BBC England

This is an antique KR crystal radio set from England circa early 1920's. It is in a nice lidded oak wood box with finger joints and has a detachable coil. Inside is a nice tuning variometer. The panel has suffered from the years, but appears mostly or all original. A relatively uncommon set, the only one I have seen from this manufacturer. $95


Miller Model 595 High Fidelity AM tuner crystal radio

The Miller 595 High Fidelity Tuner is actually a dual tuned circuit crystal radio praised as the most selective crystal radio ever made. This is made possible by the dual tuned bandpass circuit and the vernier gear reduction tuning drive mechanism. This set is in good working condition, and the cosmetic condition is good or better with some minor scratches on top and fading on the faceplate. Tested and working and I can pick up 10 or so stations here with a 15 foot indoor wire antenna. The original output cord can plug into an amplifier or you can hook up high impedance headphones. $125SOLD KZ

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.
