Original Description:
Crystal Radio Push-Pull TRF Inducted Tapped Coil With High Performance Detectors. Condition is New. Shipped with USPS Priority Mail.
This coil is for making a battery free push-pull crystal radio. Clear and loud stations can be heard when the coils are tuned well to each other. Can also be used as a trf radio if you use transistors/tubes.
Comes with 2 FREE high performance germanium detectors!! These detectod diodes are the best I have used so far. The coil form is cardboard and ...has been dried in the oven and coated in shellac and oven dried again. Resistant to moisture and durable!
22awg magnet wire for the tuning coils at 90+ turns on a 2 inch coil form fed by a 22awg inductor coil in the middle.
