Size of the PCB inside an AKG C28c microphone?
« on: March 04, 2020, 05:06:47 AM »
A friend of mine asked me to design a PCB for the AKG C28c (nuvistor) microphone.
As such, this is no problem, but unfortunately I don't know the size of this PCB and I don't have the microphone here (yet).
So: who can give me the size of this PCB (in millimeters) and preferably also the distances between the mounting holes.
Help would be highly appreciated!

Would assuming that the component holes were drilled on a (now standard) 0.1" / 2.5(4)mm grid be too optimistic? One could at least get a rough-ballpark estimate from that, i would think.

But of course, "straight from the horse's mouth" would be optimal, indeed :)

No idea if there was any 'standard' in the late '50s...
(In the meantime I asked a C28 owner to measure the PCB. I hope that will give more information.)
