Ok, thanks
The question came up on LTSpice, so I worked the optimization for the Svetlana SV811 -- the RCA datasheet only has positive Vg values:

Can somebody find the reason why this model does not work with LTspice ?

the reason why it doesn't work for AC sim is because CCP is given as 6.5 Farad (instead of pico). ........
After 4 iterations and debugging of the Extract Model tool by Derk, I managed to refine the 6e5p beam tetrode model:
The valve saturates massively above 50mA so hence the gap with the model at low Vg values. Not an issue as will never be used at these levels.

Does anyone have a Spice model for the 1J6 or type 19? I think these tubes are equialent.
I tried to create a model for the 19/1J6 using the model paint kit. It probably isn't spectacular since it is my first such model, but I'll post the model here for review.
Was I even close?

I get an error in Tina - "line 16, invalid function LIMIT"
I think there's supposed to be a parentheses in front but I still get the error.

It's the incorrect version of the code. TINA uses the URAMP, not the LIMIT function... Try this one:

I don't think so, you can check the results with this asc file.
Parts look fairly close... Although there is considerable error when the grid gets above 15.
Could you please post a picture? Is this datasheet used for the model?
Not true. TINA understands 'LIMIT' (PSpice) just fine. Since Micro-Cap understands PSpice and 3f4 spice with the limit function, I got lazy and posted a 6267 model that works in Micro-Cap, but was not in a true PSpice format. My bad... So here is a 6267 PSpice model:It's the incorrect version of the code. TINA uses the URAMP, not the LIMIT function...

Ok, that's good to know, not that I want to use TINA.
