This is an example of a amplifier modification gone wild. It is like "let's make a 1500 watt amp into a 3000 watt amp with little consideration to what you are actually doing. There is allot of RF in a small RF cavity. This is a interesting project.

Chimney

Tuned Input

A recap of what you are looking at: The transformer is a Peter Dahl designed for this upgrade. The right angle chimney moves the hot air out of the box. I have parasitic concerns associated with the long extended plate connection required to work with the chimney. The power supply mod is from a voltage doubler to a full wave bridge. I am replacing the big caps with small new units. When this unit was first completed the output was 2700 watts. This tank was completely rebuilt. Look at the wires they have melted installation and arc indications. Lots of RF in a small box can cause problems. This picture of the Dentron tuned input to control SWR from the exciter.
