Description: This listing is for the 6F8G Regenerative Receiver that you see in the photos. It comes with a high impedance Piezo headset like the red ones that you see pictured. I make these radios to order, so please allow 7 to 10 days for shipment once your purchase has been placed. The circuit uses a 6F8G dual triode tube in the traditional twinplex circuit. The spectrum coverage is continuous, from about 3.5 to 14.0 mhz. Since these made with old world analog construction, the tolerance of frequency coverage can vary as much as plus or minus 100 to 150 khz for the band limits designated. The underneath chassis photo shows a transistor amp which I've sometimes used, but not employed in this circuit as the dual triodes produce adequate headphone volume. Power requirements are 6 to 7 volts dc for the filament, capable of at least 0.6 amps (power supplies not included). You will need another well filtered dc supply (or batteries) for the detector and and audio amp circuits. Two 9 volt rechargeable batteries in series are sufficient. If you want more gain, then use 3 series batteries. The wal-wart power packs will sometimes work okay, though I've often tried some that generate a lot of hash noise which is picked up by the detector circuit. So typically I prefer battery power, or a well filtered external dc supplies. 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. Front panel controls provided are main and fine tuning, plus regen action. I guarantee this radio will work if you hook it up properly with appropriate power supply and a good antenna. These twinplex triode tube circuits make great regen receivers. Shipping to the US only......KW7T
