Continue by installing the FET transistor. I chose the original BC264, whose GATE leg is on its edge. If you
choose another FET, keep in mind that the GATE leg may be elsewhere. Always check this against the data sheet
of the particular FET transistor. Note that the GATE leg is also soldered in the air to the teflon pin.
Notice that on the board around the footprint of the FET transistor there are small marks D, S and G (= drain,
source and gate). Make sure that the selected FET transistor uses the same footprints. If necessary, adjust
according to the markings on the board. Gate leg of FET transistor solder to teflon pin as if in air. Q1 pcb
footprint on the board match BC264 (original Schoeps FET) pin out. If you plan, for example, to use 2N3819 FET
tranzistor keep in mind that the GATE pin is the middle one (always check it against the FET transistor
datasheet).
Next up is P1 trimmer resistor near the FET transistor.
