Looking at your picture, the arm to amplifier cable has probably been rewired to run a stereo cartridge, with only 3 terminals or the two ground wires have been joined in the headshell and run to the amplifier using the main ground lead.

The easiest solution should be to get hold of another SME stereo cable, they're often for sale on the net and plug it into the terminal block. Provided the cables inside the arm tube haven't been changed it should work straight away. Or you can fit an RCA socket conversion if you want to upgrade from the SME cable.

I assembled a 3009/II from parts and the arm tube is an early one with wire colours like yours. They don't match any modern standard.
To check which wire goes where, I fitted a modern headshell with the current wiring standard and did a continuity test between each cartridge pin and the end of the wires (there was no terminal block), and then the arm tube and the end of the wires. I also had to check that the arm socket wasn't 180 degrees out, as the grounded lead would short out the signal. I can't find the paper I wrote the results on, but following the pin arrangement on later arms and, looking at your photo, you could start with:

Red - Left Signal
Green - Right Signal
Yellow - Left Ground
Blue or Black - Right Ground and probably arm tube ground

The arm tube ground is probably grounded at the arm socket. I'm not an SME expert but I guess that if your arm socket is not secured with a screw underneath it is the same as mine. The cut-off black or blue wire might have gone to the base of the arm via a solder tag on the pillar screws that hold the pin block on.

I'm hoping that your arm tube is grounded, if not you will have to remove the knife edge bearing and attach a wire to the screw bolt via solder tag. It's very fiddly, check the Analog Tube Audio link posted in another reply.

I fitted the ATA socket conversion and it is very good, the screening can will not fit the ATA conversion, so far I've had no problems without one.

The other 3009/II I have is a later one, has standard colours and a separate ground lead from the terminal block to the arm tube and is grounded inside on a knife edge saddle mounting screw.

Please don't hate the arm, with the right cartridges they still sing, and are surprisingly robust.

Good luck.
