So the SubZero - SZC-100 is identical to the good old Apex - 185 and the Alctron - (HS)T-02A, nearly identical to the Apex - 180, the Alctron (HS)T-01A, the Nady CM90 and the CAD - GXL1200.  The circuit itself is very similar to the MXL - 991 too.

Use 5 pin XLR  for connection, with breakout cable to two regular XLRs.

Do you happen to know where i would get a 5pin xlr insert in europe? I think i need one with a screw to be held in place indide the mic socket. and those inserts in regular xlr plugs dont have that screw afaik..
I found the switchcraft cg5m but it seems to be only available in the us and the cheapest i found it was 10$ plus 20$ shipping :/

Nope, i used chinese variant 5 pin connector of Aliexpress.
I searched there too but couldnt find one. Could you send me a link? I have to wait for the mic body to arrive anyway so it wont matter and i can always solder the two cables directly to the pcb as some kind of interim solution first until the connector arrives .

Or maybe you have one spare that i could buy from you?
eDIT: i just bought the switchcraft one because i needed some other stuff from digikey. Now i just wait for the mic body to arrive and complete the build :)

I own the Austrian Audio oc818 dual output microphone. I have tried it with the sphere plugin. I think it sounds great. Not sure if it sounds the same as if I was using the sphere mic itself but It sounds good.

Emulations shouldn't be way off. If AA published graphs are accurate, oc818 shouldn't be way too different. They are both flat-ish mics to begin with.

C800 for example has huge boost in high end, so emulation curve should dominate over oc818's curve. Same goes for ld12, ld251, ribbons...
