Using the program curvecaptor, I did this 3f4 spice model for the 5718 triode:

* 5718 submini triode
.SUBCKT X5718 P G K
Bp P K I=(0.01551437568/1.0e3)*uramp(V(P,K)*ln(1.0+(0.1740907121)+exp((3.525439534)+(3.525439534)*((24.14586141)+(-382.6569773/1.0e3)*V(G,K))*V(G,K)/sqrt((48.65810159)^2+(V(P,K)-(34.77989095))^2)))/(3.525439534))^(1.508910632)
Cgk G K 0.8P
Cgp G P 1.3P
Cpk P K 0.8P
.ends X5718

characteristics mu=27, Rp=4.4k, Gm=6000
