Hi!
I had a good google but there doesn't seem to be a schematic around for the Syncron Fairchild mics.
http://www.coutant.org/syncron/index.html
So... I had the opportunity to trace it out, and here is...
EDIT 21/9/2011: There was a mistake in an earlier version of this. Please reload the thread to make sure you're seeing the right one.
Really very very simple. It runs on 4 obsolete mercury batteries (two pairs) which give the 8.4 and 42V supplies. Tranny uses gold plated jumpers to give circa 200 or 50 ohm output.
Construction is pretty interesting, using long thick silver plated brass (?) rods as both the structure and conductors - sort of reminds me old NMR spectrometers I used to work with in my university days! I'll post up some photos later.
I suspect there are quite a few of these kicking around unused because the batteries are unavailable. I'm just working on a mod to run off phantom... any other cunning mods or upgrade ideas greatly appreciated, as always.
