Dick W6SGJ is a very talented guy! See the photos below of his creation of the "Super Chief" from a stock Globe Chief transmitter.
It puts 50 watts out with a 6146 final and a 6146 Sliding Bias Heising modulator. Monte, W9BMW, did the panel. The sliding bias scheme came from Bruce, AB7YD. Click on a photo to start a slide show of enlarged versions.
