I sell LSK preamplifier (pcb populate). This is a dual channel preamplifier based on schematic in post # 146. I used here matched pairs 2SK170 / 2SJ74 and resistors vishay dale. It works although I have never ridden in a chassis. I've tried the air with alligator clips and had some background noise. The offset is near zero ok.
I sell it for 40 euros plus shipping.
