New Tube Spice model

Post by RFMed »

Hi everyone! I have been enjoying looking at this site. I was able to stumble upon here after doing some research into vacuum tubes. I am new to working with vacuum tubes and would like to learn as much as I can about them.

I am currently trying to model 3 RF generators in LTSpice and they use 3 different triode tubes: 1) TB4/1250 2) 3CX15000-H3 3) 3CX5000H3. Does anyone know where I can get the schematic to place into LTSpice so that I can model the tubes in the generators? I was able to find them on the tube search form but they did not have the LTSpice schematics.

Thank you all for any help you can provide.
