- Always dip the plate last. 2- Depends on why you are reducing drive. If doing so to operate cw at lower power then do a complete retune with that amount of drive. Tune for maximum output as usual and

- I have always been puzzled by the "maximum smoke" tuning recommendations of some amps, AL-80A or B, for example. A single 3-500Z in linear service is rated at 400 mA plate current. (350 mA in class C

- Grids are typically not damaged by too much current at the frequency of operation since tuning for max electrons out does not leave enough electrons to damage the grid. Instead, grids are usually dam

- It is not always easy to see flattoping on a scope. Especially when using any kind of speech processing. The processing itself tends to square off the peaks. So when you actually observe flattoping o
