Hi,
does anyone have plain voltage regulator for +/-15V using IRF610 and IRF9610..... thnx

maybe something like this???

quick draw

I think if you dig up shcematics for the Pass X-Bosoz psu it could be easily modified. (Look in the 'my take on x-bosoz' thread) I'd bet all you'd have to do is replace whatever is in the zener stack of the existing schem with a stack of 2 x 9.1v zeners (plus AND minus rails) you'd end up at just about +-15v. You could also lower the voltages of all the caps making the whole thing cheaper and smaller than a Bosoz PSU. Use maybe a 15v dual sec. traffo?

that is whyt i did up there in post 2 of this thread....need confirmation that everything is o.k...have transformer with double 17V secondaries....

p.s. i think that 4k75 needs to be reset to 1k5 if used in +/-15V right?!

i know that this all might be trivial questions - but i don't like to burn parts - i have weak hearth - so can somebody confirm that upper sch is o.k. (when 4k75 is substitued with 1k5).....please...
