LTSpice tube models

You need to convert the model so TINA can use it, just a few syntax changes. IIRC, something to do with the uramp function.

Thanks a lot!
But when used the macro wizard to import EC86.mod, TINA-TI told me line 11 "V" is invalid function......

No conversion needed if you use the .inc file. In a text editor, save the .inc file as a .cir file. File -> Import -> PSpice netlist, load .cir file you saved -> compile.
Tools-> New Macro Wizard, blah, blah. 😀

Hi
Yes! It works!
Thank you very much!
Still looking for the model for EC88 and EC8010.....please help.

cheers

You can make your own with Dmitry's model paint tool, very easy to use and accurate.

I made these using Andrei's Curve Captor.
Grid current is NOT modeled.

In the above models, the diodes are merely there to help in convergence. If you prefer not to have or need them, just comment (*) them out.

Thanks for great help!
