Roger:
?The closest mosfet in my Micro-Cap library was a 2SK311 to the 2SK3563 that I was proto-typing with.?
Since these mosfets are much higher current parts, than those you may have used in your sim,? they don't work as well in the simulation I ran using a 2SK311,?
I had to tweak R6 to 6.8M to get the circuit to work and as you simulated, temp stability is great.?
Now I have a few more things to cobble together tonight.
I looked up the part I will be using its a Rohm MTZJ-6.2? zener.
will try to make time this evening to melt some solder
