Hi Evert, Not all doorknobs caps are created equal. This may be of some
help, paying close attention to Type I and Type II materials.

Hello,

 

When using doorknob capacitors for RF tuning circuits, is there
something
special I should aware off?

(special quality, specific "family")

 

I'm looking for on a 300pF/30kV in my 160 mtr amplifier

 

Thanks
