SWT Arcade (Model 3) to RetroTINK-5x Considerations

[DrBackhands]

I'd like to run a Sega Model 3 (SWT) to a Retrotink5x (to my Sony plasma display). RBGS video is coming from CN6. Other than attenuating the sync with a 470ohm resistor (the cable I'm using has no attenuating components built in), is there anything else I should be aware of before testing this out? Are the RGB lines ok as is?

I'm alright if the medium res causes headache during my tests, I just don't want to fry my setup. Any help's appreciated, thanks all!

I made a sort of high-pass filter, attenuating the lines with resistors and isolating the signals with capacitors, but now I'm not getting any video. I tested the video going VGA straight to my PC CRT with no problem, so I wonder if I've botched this attenuation circuit?

Seems the circuit isn't the issue (well, other than that the RGB lines did not need attenuation). It works fine with a GBS-Control, just not with the TINK 5x. I wonder if the TINK has trouble detecting med res signals.
