I got similiar mics for dirt cheap. I want to test the differences betwen FET with P48V, Country Boy and S52 circuit.would be cool to know. I haven't built my mic yet, but have a TEAC mic with an EM21 and and old MXL that are ready for new guts.
Thanks for feedback!I think it should work. Imho C2 is not needed. Check 'country boy' microphone schematic for inspiration too.
Did you end up preferring the version 1 or version 2 schematic with this mic? I'm about to build mine.I built second S52 microphone. Thank you Piotr for great design and all tips. For this mic I used 10pF C0G feedback capacitor for lowering the output of microphone. In C1 position I choosed 3n3F cap and in C2 1nF capacitor. R3=100M and plate R6 resistor 200K. Im going to build another two microphones.
Stock BM80 (and also Pronomic) capsule sounds a little bit "harsch" compared to Maiku SDC capsule. Cant recommend Maiku SDC capsules more. Capsules from Banzai´s KM84 body kits fit on ISK BM80, Pronomic SCM-1 bodies...
