Try this one:


.SUBCKT 6AH4 A G K
BGG GG 0 V=V(G,K)+1.2375
BEP EP 0 V=URAMP(V(A,K))+1e-10
BSTM STM 0 V=URAMP(V(GG)+V(EP)/7.262)+1e-10
BM1 M1 0 V=(0.040277471770862*(URAMP(V(EP)-1e-10)+1e-10))^-0.620126359531028
BM2 M2 0 V=(0.707505*V(STM))^2.12012635953103
BM M 0 V=V(M1)*V(M2)
BSTP STP 0 V=URAMP(V(GG)+V(EP)/10.2642384152762)+1e-10
BP P 0 V=1.72936766471006*V(STP)^1.5
BIK IK 0 V=U(V(GG))*V(P)+(1-U(V(GG)))*V(M)
BLIM LI 0 V=0.88*V(EP)^1.5
BEG EG 0 V=URAMP(V(G,K))+1e-10
BIG IG 0 V=0.88*(V(EG)/(V(EP)+V(EG))*1.2+0.4)*V(EG)^1.5
BIP IP 0 V=(V(IK,IG)-URAMP(V(IK,IG)-V(LI)))
BIGK G K I=0.0011961*V(IG)
BIAK A K I=0.0011961*V(IP)
CAK A K 1.7e-12
CGK G K 7e-12
CGA G A 4.4e-12
.ENDS

Or this one:

.SUBCKT 6CK4 A G K
BGG GG 0 V=V(G,K)+1.3222
BEP EP 0 V=URAMP(V(A,K))+1e-10
BSTM STM 0 V=URAMP(V(GG)+V(EP)/6.0997)+1e-10
BM1 M1 0 V=(0.0556199485220584*(URAMP(V(EP)-1e-10)+1e-10))^-0.77019909646076
BM2 M2 0 V=(0.660735*V(STM))^2.27019909646076
BM M 0 V=V(M1)*V(M2)
BSTP STP 0 V=URAMP(V(GG)+V(EP)/9.23168895245446)+1e-10
BP P 0 V=1.67095052790759*V(STP)^1.5
BIK IK 0 V=U(V(GG))*V(P)+(1-U(V(GG)))*V(M)
BLIM LI 0 V=0.88*V(EP)^1.5
BEG EG 0 V=URAMP(V(G,K))+1e-10
BIG IG 0 V=0.88*(V(EG)/(V(EP)+V(EG))*1.2+0.4)*V(EG)^1.5
BIP IP 0 V=(V(IK,IG)-URAMP(V(IK,IG)-V(LI)))
BIGK G K I=0.00185*V(IG)
BIAK A K I=0.00185*V(IP)
CAK A K 1.8e-12
CGK G K 8e-12
CGA G A 6.5e-12

They might neeed some reworking, haven´t tried them myself. Think you have to exchange ^ for **.
