I had purchased several MiSTer SCART cables from other vendors years ago, and even though they might have worked on professional video monitors, when used with an RGB-modded consumer television, I wouldn't get proper sync. I just modded an Toshiba 19a21 and I tested my old cables with the mod - and neither of the two I had worked, so I ordered this one - and that 470ohm resistor on the sync line solved my issue completely. I am now enjoying my arcade cores on beautiful shadow-mask CRT with no noise of any kind and perfect sync. I discovered settings in this Toshiba set I am using to adjust the Horizontal Voltage Controlled Oscillator - and now even games with odd sync times work perfectly - but none of it would have worked without this cable. I won't buy MiSTer accessories or prebuilt systems from anywhere else... everything these folks do is golden. Thanks for the kit!!!
