#16 Cheap chinese BM700 / BM800 microphone modding / upgrade, part 2 (CK12 & K47 capsules)

<Continuation from part 1>

After quite a while, i "finally" got around to modding the other three BM800 mics i had. Just for the hell of it, i decided to make a matched triplet (to use as, say, three overheads on a big drum set).

I went with more of my modded-Schoeps boards, and matched components between them, as closely as i could (within reason, at least). Resistors were no big deal, and neither were the capacitors; one of those cheapo chinese ATMega328-based "component testers" helped with matching the JFETs and PNP transistors. No, i didn't necessarily care about the absolute values, just that they're the same (or as close as reasonably possible).

#12 Cheap chinese BM700 / BM800 microphone modding / upgrade (to say the least).

<Part 2 can be found right over here>

Last year, after hearing (or rather, after reading) about these cheapo BM700 / BM800 microphones, over on the GroupDIY forum, i decided to get a few myself. They were cheap enough (under 20 bucks a piece), and i figured they would, at the very least, make for reasonable enough donor bodies.

Some credit is due in no small part to Mr. Henry Spragens, whose microphone section on his blog served as a considerable portion of inspiration for this endeavour. Said blog is a fountain of knowledge, testing and ideas for anyone interested in condenser microphone modding or even building from scratch.
