[Currently in construction]
Cardioid/Omni
Edge terminated capsule - AKG 2072 Z 2009
Haufe T14/1 transformer
5899 Tube.
All carbon Beyschlag resistors - same type as in ELAM 250.
Capacitors also same type - two tubular ceramic and two wet tantal.
Would be great to get voltage specs of original (or even clone) unit with AC701k.
For 100% there would be need to change cathode resistor value but for that - original voltage specs are needed.
I started separate topic about the voltages, but feel free to put any info here
