neumann n61 schematic



Hello, I just hand wired a cmv 563 with a two cap circuit on Oliver's Mod and his 551 optimized tranny with a Thiersche M7 PVC(-M49 style capsule voltage..). This Mic is the most linear '47' you've ever heard! However, it is stuck in 'Native Omni'. What type of switch to electrically disconnect the rear diaphragm? Normally closed? spdt?
I'll built it on top of a Trion 8000(gutted) and the existing 3 way switch is 'OK'.. but not a two state.

Also, does anyone have an N61 schematic? If not, I'll just add a tube rectifier to my DC Servo fed re- built CAD supply. With Black Gates/Relcaps.. it is very quiet! Need COOL at the moment!
