Default Heat issue on FET

hello again! ?
planning to run this with 75mA@410-420vdc to 300B b+
have discussed the implementation of this reg. on a Norwegian forum, and there has been suggested that heat dissapation from the FET might be an issue;
would a possible solution be to parallell 2 FETs, to bring the heat down on each?
could no 2 be "mirror fixed" on the underside of the pcb with it own heatsink?
opinions anyone?
best
Leif

What op amp did you use? Anybody get this board to work properly (no oscillation) with the OPA656 op amp?
Thanks, Daniel
Dan, did you ever build and get this reg working properly?

I got a few requests lately for this PCB. I'll make a small run of 10, at 25$ each + shipping and 3%PayPal fee. I already have 4 sold. Let me know at bergeron.syl@videotron.qc.ca.

Thanks...
