Thanks Kubi
I have this. Do you see 110 or 120VDC?. Everyone talking about 120VDC for ELA M, but I see 110VDC 1,1mA.

[quote author="kubi"]The trafo on the schematic is wired for 117V ("US-Dose"), but you can also wire it for 127V, 145V, 225V, 245V. See the taps.

I am talking about 110VDC to feed microphone, not about mains voltage
Thanks
