Shure PG42 microphone

[LevinGuitar]

Expected to find Takstar internals and capsule but instead it's a 797 made. Flat circuit, bright capsule... but the dome is nice.
Haven't traced the circuit but since it have one of the "output" 22uf cap connected to ground on its negative lead, maybe it's something in the Behringer B1 way. -50v polarization on diaphragm, backplate connected to ground. 2N5457 fet, 470pf imput cap. Easy to rewire the capsule to skip that imput cap and gain 4.5v on polarization. Lower noise than the new B2 btw.

I keep wondering if there's some hidden reasoning behind using worst possible coupling cap for the capsule-gate connection. I don't think it's just cost cutting.

And aren't those carbon film resistors on the output?

Is it made in China?

As far I know, PG line is made in China.

The amplifier circuit is not exactly as the Behringer
The source of the Fet goes to Q6 -> C11 (10uf) -> Q5 -> Q7 -> C15 (22uf) -> inductor -> R19 (47r) -> pin2.
