it is not ideal for Ortofon MC30 Super requiring 10 ohm load, but is shall be OK now. Internal wiring of SME was less than 20pF but DCR was 1 ohms/conductor.

This is still a bit high as recommendations for MM capacitive loading do vary from 150-300 pF Ortofon, 275pF Stanton, 200-500pF Shure V15. I suppose that this is the figure that cartridge will see in parallel to phono input. Now I measured capacitance from positive feed to negative feed tied to common screen and capacitance was 330p. as I paralleled 2 conductors to archive lower resistance, it seems that this increased capacitance to two other paralleled conductors and common screen. I really do not understand does cartridge only see capacitance between signal conductors or do capacitance against chassis ground also load cartridge. but if MM cartridge will see both capacitance´s in parallel. When using MC:s this should not be any problem. but capacitance between ea signal conductor and chassis ground is 300pF. However separating audio ground from signal ground created situation where capacitance between signal conductors is 220pF. This way I can ground tonearm and conductor shields to preamp chassis ground or turntable chassis, whichever proves to be better alternative. I connected shields of both channels and tonearm ground lead to 4-pin connector tonearm ground lug. I ran balanced feed from cartridge to output RCA:s without connecting them to shield. I used 4 conductor shielded cable for rewire and connected 2 wires in parallel to reduce resistance. I got 4-pin inline connector open with help of oven heat and rewired it.
