TNT Transmitter using a 45 tube

This is my TNT transmitter typical of the late 20's early 30's. This rig uses a 45 triode and puts out 2 watts of power. It was built using period components. I have coils to operate on 80 and 40 meters and it is set up for 80 in the video. This is lots of fun but requires careful tuning to produce a stable note.

Nice rig Joe, I have a 245 TNT too.

These old style rigs are a lot of fun and surpisingly effective.

Joe a crystal Hartley is quite a bit different than a tnt transmitter?

Hi joe,

I as well have an interest in early radio.30 meters is where I want to be and I am working to build a transmitter like yours.

Fine work and enjoyed your video

mine uses a VT-4C with 750 volts on the plate

can get a big 10 to 15 watts out on 80 meters
