Homebrew AM Broadcaster

AM Transmitter, Broadcaster. Michael Holley

I built this AM Transmitter in the late 1960s. I don't remember if it was based on a magazine article or a new design. The design is based on the J.W. Miller 522 Phono Oscillator coil.

I no longer have any documentation on this transmitter. Here is the schematic I created from the completed unit. (PDF)

Here is an example of my early work in tube wiring.
