Thanks +T, i had seen that first one, but not the second.  Trying to make a very small phantom supply for something.   ;D

EDIT: Seems the second link is basically just about wiring the electret capsules to phantom, they have a second on where to obtain a phantom supply but not much else.

Perhaps someone has the skematic of the PS-2?

damn....sorry about that.  3rd time is a charm?

here's the link: http://www.jensentransformers.com/apps_sc.html


the jensen tranformers website has all kinds of mic pre schematics with the phantom power.  you should be able to piece the info together with all those sites and this thread:
