Hi guys,

Does anyone have any schematic (and pcb pinouts I guess) symbols for triode and pentode valves that they would be willing to share? PCB pinouts would be for the sockets obviously...

I'm looking for specifically: Dual Triode (ECC83 type) and Pentode (El34/84) types.

These are particularly tricky to draw so I thought why "re-invent the wheel" if this has already been done.

Anyone?

Thanks!

That's a good start but I really need the Schematic symbols...

Someone must have them :)

I managed to get hold of a KiCad symbol library (in Zip Format) that allegedly contains valve symbols.

Does anyone know if you can import or convert a KiCad library into EasyPc format?

If I can then it's job done! If I get it done, I have no problem posting the library here if it helps others.

Anyone done this?

Oh, and unzipped, it consists of a .dcm and a .lib file.

Quite honestly it would only take 10 minutes to create your own schematic symbol. Save yourself a lot of hassle !

Hi!

Having been asked this exact feature by several Members of the Vintage Radio Forum, I have begun writing a step–by–step tutorial book on how to design a complete Thermionic Valve and Cathode–Ray Tube Library for DS PCB and Easy PCB!

It'll be a fairly thick document, I'm already up to page 9 and I've only got as far as "Valve Envelopes" so far!
