This listing is for 1625 Regenerative Receiver similar to the one that you see in the photos except that it has plug-in coils for expanded frequency coverage (535 khz to 14.4 mhz approx).

This radio comes with a high impedance piezo headset, just like the red ones that you see pictured. 

I make the radios and accessories to order, so please allow 7 to 10 days for shipment once your purchase has been made.

The circuit uses the traditional 1625 pentode tube, plus a one transistor, built-in headphone amplifier. The radio works great, with good headphone volume.

The spectrum coverage is continuous, from about 535 khz to 14.4 mhz.  

Power requirements are 12 to 14 volts dc (600 ma.). No power supply is included in this listing.

You will need a wire antenna at least 25 ft. long and a good earth ground. You'll pick up more stations with a longer antenna, 50 to 100' in length. I'm able to copy tons of stations in the early evening and early morning hours, including stations on the amateur radio bands. The fine tuning control will allow you to clarify ssb and cw signals. 

A hand sketched wiring diagram will be provided, along with instructions on where to hook the antenna, power and headphones.

About 80 to 90% of the parts are new. Since a few of the parts are from good used stock I am listing the radio as used, even though most of the parts are either new or nos. Controls are main, fine tuning, and regen action.

I guarantee this radio will work if you hook it up properly with appropriate power supply and a good antenna. These power pentode tubes make great regen receivers and the added one stage transistor amp gives you ample headphone volume.
