    Description

    This listing is for the vacuum tube Regenerative Receiver that you see in the photos. The ST version of the pentode 42 tube is used for the detector. Also included with the radio are several plug-in coils, a high impedance piezo headset and an 8-pin plug-in connector/wiring harness for your power supply.
    I make these to order, so please allow 7 to 10 days for shipment once your order has been placed. Chassis colors are green, black, gray, blue and red. Please let me know if you have a preference.
    The circuit uses either a rare 1930's 42 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 530 khz to 14.3 mhz--using several plug-in coils that are included in the listing.
    Power requirements are 6 to 7 volts dc for the filament and 20 to 30 volts dc for the regen amp circuit. Please do not use ac voltage for the filament. This is a big no for regen radios, as it will inject ac hum into the audio. You do not need a separate power source for the transistor amp.
    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 and fine tuning, antenna coupling and regen setting.
    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 plenty of headphone volume.
