i finished my project around the ef12 tube. the design originates from the circuit i posted recently, but i got rid of the ec92 stage.
like my first mic pre i build a small case with exernal psu, i can run both pres from one supply.
some pics from the new one:
edit: changed cathode resistor to 2,2k
