Sorry about that. I replaced the symbol file with a generic one, "Diode_Valve.asy". I've also added a directly heated half-wave rectifier symbol. You can copy those to your .../lib/sym directory.Sorry,
it does not work. The Symbol Need the tube.lib file. This is not in my System. Is there another model out?
Thanks for Help

I have attached the corrected zip file below:

Hi cogsncogs, thank you very much for you time to create a LTSpice model of 6KY8A triode section!

Since there isn't any data given for the suppressor grid, how do you build a model, and for what purpose?There are 12BY7A model on this thread, and another by S.Bench, both have suppressor grid connected to tetrode.
Great thread, guys. I just read the whole thing and look forward to trying out the models that I have found.
In the spirit of giving back, here is a zip file with all the models in the thread. They are all in LTspice format (although I may have overlooked something along the way). Each model is in its own file. Just extract it to the directory c:\Program Files\LTC\LTspiceIV\lib\sub (or ~/.wine/drive_c/Program Files/LTC/LTspiceIV/lib/sub for the Linuxheads like me, hehehe) and have fun.

Excellent, thanks very much!
One question -- Which version of 6AV5 is the model based on? 6AV5GA? Also, which brand's data was used? Sylvania? GE? RCA? Other? There's been much discussion on the relative robustness and performance of different versions of this particular tube. Tubelab has posted about varying dissipation limits between versions. I'm not sure if that impacts characteristics that would affect the spice model...
thanks again for this.

You are welcome, the model is based on the GE datasheet which is pretty much the same as the others. If someone can trace some triode curves for the more robust ones, I can make a model for it.Which version of 6AV5 is the model based on? 6AV5GA? Also, which brand's data was used? Sylvania? GE? RCA?

looking for this schematic in ltspice, hope not asking too much. thank you
There is nothing special about the design, it uses all standard tubes which are available from this thread and elsewhere.

This is the triode connected version.
