As I do not (yet) own a decent LCR meter does anyone have a decent ball
park figure for the stray C to chassis for a 3CX800A7? The side walls
are 1.25 inches away from the tube and the lid is 2.5 inches above.
Also thanks for all the help with my previous questions. I should
mention that this is a retrofit to an existing 2m amp and C1 is 6pF
maximum and I would like to use this part if at all possible.
I have a design that works on paper for strays C of 4pF with a Q of 8
using an L-Pi-L configuration as recommended by a few of you. The 4pF
stray value does not seem unreasonable but it is a guess. I am sure that
someone must have measured this.
