Yours was one of the first upgrades done and so I apologize for the lack of documentation. The uppermost RCA's are the MM inputs, the lower inputs are MC. The switch should be toggled up for MM and down for MC.
The loading switches are as follows:
1 up = 100ohm
2 up = 100ohm
1&2 up = 50ohm.
3 up = 1K
4 up = 1K
3&4 up = 500 ohm.
5 up = 8K.
When MM is selected, these inputs are set to 47K
Please email me directly if you have any further questions.
Thanks,
Dan
