These are quite antiquated tubes... you can try making the models with CurveCaptor yourself.

Thanks for that!
In case if someone needs:
Code:
.subckt ABC1 P G K
Bp P K I=(0.03461462647m)*uramp(V(P,K)*ln(1.0+(-0.09451114315)+exp((4.492501276)+(4.492501276)*((27.91471754)+(-293.1782318m)*V(G,K))*V(G,K)/sqrt((31.13718048)**2+(V(P,K)-(6.760356504))**2)))/(4.492501276))**(1.200237187)

Is anybody has soviet 6S28B/6S29B tubes model?
The datasheet is found here.
Not sure you can model it, try.

I have not found EL82 model. Does anybody have ?
If it helps, I stumbled onto triode curves, here:

Thanks Koonw.
Hey artosalo, would 6P18P be close enough to EL82 for you to use? Maybe you'll want to give it a try.
I've attached a 6P18P datasheet. Interelectrode capacitances are in there.

hi, I need the ltspice model of the subminiature jan 6418 valve connected to a triode.
Triode curve is included in the datasheet. Noted the capacitance values are not listed.
Code:

.subckt 6148 P G K
Bp P K I=(2.232751379m)*uramp(V(P,K)*ln(1.0+(-0.1251078596)+exp((9.293821508)+(9.293821508)*((7.752252766)+(-9.512594942m)*V(G,K))*V(G,K)/sqrt((2.911290527e-008)**2+(V(P,K)-(0.3137181941))**2)))/(9.293821508))**(1.896157386)
