Last night I put a headphone on the amp and fed it with a antenna through a diode I received signals. Without the diode all is quite. For the test I used a tapped coil. I could move the tap and receive different stations. This would be a good amp for a hollow state version of the 40/80.
|Using the cap divider powered tube amp as the AF stage|
of this receiver would be a cool and interesting project.
It could use a lambda
diode oscillator or a tube oscillator.
