Replacement pcb set for AKG C414B-ULS

These boards fit C414B-ULS and should also fit the C414B-TL and others of that era. I don't think they will fit the modern C414s and I have no idea about the earlier 70s models.

This is a pair of boards, one is a schoeps style mic amp, and the other is a dual polarisation generator designed to create the same 4 polar patterns the mic originally had.

There is no provision for a pad or HPF as on the original, as I don't use those functions. However a pad can be implemented with a single cap mounted on the switch so provision on the PCB isn't really required.

I am considering making a version of these that uses an opamp circuit rather than a Schoeps circuit as I think this will sound more punchy and neutral and more similar to a C414B-TL. Ask if you would like those and I may do it sooner.
