jleaman · 8th March 2005, 06:50 PM

Well Dave ( planet10 ) and i have asked Brian-Gt to d up a nice board layout for a 15V regulator for op-amp's and other things that i am currently Building. Is any one interested in some of these board for there home op-amp's and active X-over's ? Schematic and board layout will be posted...

I had mentioned it to brian some time ago... (this isn't the one i was encouraging him to develop) it would be nice to have one without space for a transformer.

I dont see any point in that. The pourpose of this board is to have every thing on a small board INCLIDING the small board mountable Tranny..

Maybe for you... but for someone with a whole bunch of transformers that won't fit there, and who would prefer to use a trafo that isn't subject to DC-offset, it is just a waste of board space.

How big of a transformer do you Plan on useing ? And.. These are not toroidial transformers were useing here either. : O ) ( i don't think )

I would suggest doing the board with a transformer, with the option of separating transformer's section off, if someone doesn't want it (with one scoring line). The difference in price for an extra transformer space should be negligable, and such board would accomodate everybody.

Also, footprints for TO220 diodes would be nice to have.

Excellent idea Peter... you are getting quite adpet at making one design jump thru many hoops... i have an XO design in my head that will try to do some of that too...

Salvaged EIs most likely (bigger, need to take care with shielding, but don't suffer from DC saturation -- and most importantly are already on hand).

The trafo spot looks the same as the one Brian designed in for his prototype phono baord which was a potted toroid.
