B&K 2812 info / schematic?

[rstreber]

I have a pair of B&K 4003s with the old 2812 power supply/preamp, and I've heard that the preamp section of the 2812 can be bypassed so that it just powers the mics. Can anyone here explain how to modify the 2812 to do this, or does anyone have a schematic for it?
Thanks!

Hi rstreber,

Try contacting B&K/DPA in Naerum, Denmark - they have very good service. They often faxed me info when I was in a hurry..
