Does anyone have the specs for an Electro-Voice M-26/U microphone?
I bought one a while back and can't find any tech info on the E-V
site, which is generally pretty good.
It looks identical to the 630 series, but without an on-off switch,
and the nameplate is stamped 12,000 Ohms.
I'm guessing it's just a high impedance version of the 630.

Thanks & 73
