[Amps] Design for plate stripline for 144 MHZ

[kc4mne at bellsouth.net]

Going to build a 144 MHZ amp using the 4CX800 tube. How are the dimensions and locations for the plate stripline and load and tune capacitors designed, as well as the influence of the surrounding enclosure, standoff heights, etc. I want to use doorknob caps for plate dc blocking, not the ptfe sheet method. Any help on how this is designed would be appreciated. Any software out there?
