FDV301N,multisim pspice model, maybe not finished.

I have been changing this component to work in multisim,I dont know if it's useful for audio but I wanted to try..

The model below works ok but I'm not sure abute 5=vtemp because it wouldnt work when entered in .subckt or I did something wrong in the database manager..



EDIT: sorry ,, just realised I maybe was supposed to post this in the sticky spice thread.. I was a bit too fast there..
