Spice models

[Grahamm]

Hi
I am looking for both pspice and xspice models for 6C45pi and 6H30pi tubes.
If someone can perhaps explain the syntax differences, I shall be most grateful.

Here are two that i had around from someone else's site:

.SUBCKT KTRIODE A G K
+ PARAMS: MU=37.58299 EX=1.132166 KG1=428.9745 KP=402.1368 KVB=321.0256

+ LG=0.2U VBIG=-0.2 EG=1.0389 KG=0.000769 KRG=3.685584 KVG=0.090943

+ CCG=2.4P CGP=3.9P CCP=0.7P CCH=5.6P

E1 7 0 VALUE = {V(A,K) / KP * LOG(1 + EXP(KP * (1/MU + V(G,K) / SQRT(KVB + V(A,K) * V(A,K)))))}

RE1 7 0 1G

G1 A K VALUE = {(PWR(V(7), EX) + PWRS(V(7), EX)) / KG1}

RCP A K 1G ;

C1 G K {CCG} ;

C2 G A {CGP} ;

C3 A K {CCP} ;

C4 K 0 {CCH} ;

E10 10 0 VALUE = {IF(V(A) - V(K) > 0, V(A) - V(K), 0)}

E11 11 0 VALUE = {IF(V(G) - V(K) > VBIG, V(G) - V(K) - VBIG, 0)}

E12 12 0 VALUE = {(KG * (V(11) ** EG) *

+ (((KRG - 1) / (KVG * V(10) + 1)) + 1)) + LG}

G2 G K VALUE = {IF(V(12) > LG, V(12), LG)}

.ENDS

and this one:

6C45Pi Spice 3F4 model
.subckt 6C45Pi P G K
Bp P K I=(0.005984658048m)*uramp(V(P,K)*ln(1.0+(0.0202889 9001)+exp((7.114994862)+(7.114994862)*((56.6867859 5)+(336.3011671m)*V(G,K))*V(G,K)/sqrt((7.450118654e-006)^2+(V(P,K)-(-10.58802286))^2)))/(7.114994862))^(1.976888442)
Cgp G P 4pF

.ends 6C45Pi

I think I got them here:

Thx aletheian!

Or here (dunno if it's the same, spice is beyond me): http://digilander.libero.it/paeng/projects_frame.htm

I would point out (having measured about 60 6C45):

(1) There is a big difference between "Cold War" and more recently manufactured 6C45.
(2) Even the "Cold War" 6C45 had a large spread.
(3) The published curves are rather optimistic.

Thanks for the help so far. With respect to Pspice and Xspice differences, would anyone be able to tell me how to edit a pspice model 6C45 and 6H30 so that I could use it with an Xspice simulator (or the other way round for that matter)?
