Re: Good 3F4 models for 6SL7, 6SN7 and 12BH7

for example:

Bg G K I=(0.2079346639m)*uramp(V(G,K))^1.5 *
(((14.97041148)+V(P,K))/((9.844374217)+V(P,K)))^4

should be:

Bg G K I=(0.2079346639e-3)*uramp(V(G,K))^1.5 *
(((14.97041148)+V(P,K))/((9.844374217)+V(P,K)))^4

in circuitmaker.

Hope this helpes,
