47-1230 replacement phono cartridge
#1

So I am replacing the original phono cartridge with a replacement from VOM. Vom emailed me supporting info(pdf file). The  2 leads from the phono cartridge go directly to the impedance matching transformer mounted in the bottom of the cabinet. 
I assume I don’t need the transformer and I can connect directly to the chassis. In the enclosed pdf file he says he connected to the phono/radio switch. Pb 1 is power to the phono and FS4 is the front knob selector. My question is do i go to FS4 -7 and what is the advantage? Or to the female RCA plug (phono input)? Also the cartridge has two leads at the phono arm, red and black, does the black go directly to gnd? The little round plug at the transformer has 3pins, the red , black and shield. Any help is greatly appreciated.     [attachment=27825I
