capacitor variable homebrew

This is a universal component that could be used in any circuit be it a tuner amplifier or whatever you please. This part is to be used in the plate and also antenna tune tank output circuit of the home brew high frequency Kilowatt amplifier with slight alteration in material thickness proportional to the voltage of each stage. I hope you get the urge to build some home brew equipment from this simple production video. No liability! Stay well and stay tuned.

@rredbeak Hi Rod have just checked the spec with enginering grade measuring calips and the plates are 1.668mm and the gap is 3.6 mm (average.)

Should be a bewt hope to have this amp and the rest of bits runing soon/some day, balancing family/study and other hobbies of course. E... 73

I am yet to fab my high voltage tester however the math should be good for 1Kw easy buddy.

Regards,

E.
