Default Spice models for 2SA1837/2SC4793 ???

Would any of you happen to Spice models for the Toshiba
complementary pair 2SA1837/2SC4793??

While I'm at it, why not repeat the good old request that never
seems to get an answer anywhere on the net, spice models
for SB649/SD669.

Spice models for 2SA1837/2SC4793 ???
I had the same question, seems nobody answered. Since this is a popular driver pair I thought I'd bump this thread.

What I have found so far is from a Russian website:


.MODEL 2SC4793 NPN (IS=0.1P BF=130 NF=1 ISE=0.1P RB=1 RE=0.1 RC=0.2 VAF=500 IKF=3 TF=1.6NS CJC=100P)

.MODEL 2SA1837 PNP (IS=0.1P BF=130 NF=1 ISE=0.1P RB=1 RE=0.1 RC=0.2 VAF=500 IKF=3 TF=2.28N CJC=150P)
