Any help appreciated.

Hi Jan

Can help you out with one. The sanyo pair is impossible to get and is a discontinued transistor but excellent if you can find some.

.model Q2sa970 PNP(Is=465.4f Xti=3 Eg=1.11 Vaf=57 Bf=407.6 Ise=4.683p Ne=2.051
+ Ikf=.3998 Nk=1.192 Xtb=1.5 Var=100 Br=1 Isc=465.4f Nc=1.048
+ Ikr=6.032 Rc=2.343 Cjc=11.59p Mjc=.4014 Vjc=1.155 Fc=.5 Cje=5p
+ Mje=.3333 Vje=.75 Tr=10n Tf=1.252n Itf=1 Xtf=0 Vtf=10)

Thanks homemodder

That was one..... Three more to go

The 2SA1540/2SC3955 can be purchased as KSP/KSE made.

Thank you so much, aparatusonitus

Has anyone though off making a Spice library here at diyAudio ?

[homemodder]

Good idea, but most keep the files to themselves for some reason.
Jan i have quite a vast Jap transistor file, ill email it to you.

Jan somehow my msn email is not allowing me to attach documents at the moment, if you online on your messenger ill log in and transfer it this way.
