Here is the pdf for the hv reg. My old site is down. So I've put it up here.

hello
are there any reasons for not implementing this in an all out 300B design feeding the 330B b+ in a LCLC config?
already have the SuperReg on the 6s45 driver b+
any mods needed?300 B runs @75mA neg bias around -95vdc Tommy Hørning OPT

Har anyone built these with any success? I have 4pcbs unpopulated for the time being.
Still wondering if I shall finish them.

i guess not......

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?

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?

Audiohifi · 29th May 2011, 12:50 PM

I use OPA655 Dip now discontinued I think
OPA656 is surface mount

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...

Four PCB to Gilwintan
two to jormajj

Only 4 PCB left...
Let me know.

Thanks.
