   NOTE:  Sorry, no longer accepting Paypal for domestic transaction. Check or MO by mail.
May have exceptions for overseas transactions. My state, Virginia, has decided to require reporting of Paypal receipts to the IRS, resulting in the receipts being subject to federal and state tax. There used to be a $20,000  allowance to allow for hobby sellers to operate without taxing up to that amount. Now all Paypal receipts are taxed as income so I lose about 35% to taxes and can't afford that. I don't operate this site to make money, and most of what I sell is about a break even for what I have invested, but can't afford to lose money on it. Sorry for the inconvenience, but we have our greedy governor and state legislature to thank. The states of MA and VT doing the same.

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.


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.
Selling off some of my prototype one tube radios below:

One Tube Radio Prototypes Selling off some of my prototype radios for roughly what the kits used to cost, as am out of many of the parts to sell the kits.

AM Broadcast band one tube radio prototype, with headphone

One tube regenerative one tube radio using a submini 6418 pentode tube. Works well across AM band and will include battery holder and clips for the batteries. Uses1.5 volt A battery and three 9 volt batteries for the B voltage. The single sided earphone shown is also included. $49HOLD SK

Shortwave one tube radio prototype with headphone

One tube regenerative shortwave radio using 1C5 tube. Built as a prototype but selling off these sets now. Includes the single sided earphone and clips for the batteries. I can also include some extra toroids and wire if you want to wind some coils for other frequencies. I think this one tunes around 10-12 mHz but I haven't been able to nail down the frequency range. $59

Prototype AM broadcast band radio using 1C5 tube

Last one of my prototype radios to sell, this one is AM broadcast band using a 1C5 tube and ferrite coil. Uses 1.5 volts for filament and 36-45 volts for plate. Will include battery clips. You will need to add antenna and ground wires, batteries and high impedance headphone. The red handle switch on it doesn't do anything, was installed for another project. $39
