I'll throw my triode connected model into the ring. Made using Curve Captor from Siemens data sheet.
Code:
* D3a triode connected pentode LTspice model
* Modified Koren model (8 parameters): mean fit error 0.499405mA
* Traced by Wayne Clay on 6/24/2015 using Engauge Digitizer and
* Curve Captor v0.9.1 from Siemens datasheet.

naither did I...but I keep searchingHI there guys,
Anyone have the D3A LTSpice model?
I can't seem to find it using "search this thread"

Hi all,
A belated (probably too long) upload of 6F12P curves. Both pentode and triode sections and some useful measurements:
6F12P a great Russian valve – Bartola(R) Valves

I'm getting really wacky results in a known working circuit. using LTSPICE VII on mac. Duncan's works. Am I doing something wrong using pentode2.asy? Basically the sim shows -54 dB at 100K and sloping down to 20 Hz

Thanks for providing the Nutube model Jazbo.
Anybody know how I can make this connection marked in red in LTSpice?
