I need help making a cavity tube amplifier.?
Hi i need to make a High Power narrow band VHF amplifier using a pentode. I would like to use coaxial cavities for input/output coupling. Anyone knows how to design such amplifiers? Please provide any equations, online design resources or relevant forums that would help me out.
Here is a fairly easy circuit with an explanation. The pentode circuit is about halfway down on the page.
