Ok, how does one go about building a tuned input for a 144 mhz amp, using a YC-156 tube ??
The input C on the YC-156 is huge,? 92.5 pf? ?( grid to cathode).?

This is for a cathode driven? ?YC-156

?

( The 1/2 wave tank for the output side is fine, and tunes up fine, with calculated RL.... to the 50 ohm output.)?

The output is not the issue, it's the input.?

?

What options, if any, do we have ?? ?What's the fix ?
