Hi, I have these two complementary amplifiers that operate on class-C.

I want to have a way to gradually convert both them into class-B, using a dual or preferably a single potentiometer (if possible) to do so.

By adjusting the potentiometer, I would gradually pass from class-C into class-B.

I guess some kind of biasing trick must be done.

Can you help me on this please?

You can introduce a potentiometer in the biasing network of each transistor to adjust the base bias voltage gradually. This will allow you to control the conduction angle from class-C towards class-B. To use a single potentiometer for controlling both transistors simultaneously, you can use a dual-ganged potentiometer.

Can you give me an example in My circuit, especially the pnp? It might sound trivial but I would like ti see it
