Hantarex monitor connectors

I asked on UKVAC forum about replacement Hantarex connectors for a tube swap I am currently doing but didn't have much luck when it came to finding new stock. It seems most were under the impression that Hantarex used custom connectors not available to the public, it was pointed out there are compatible housings. The problem with the compatible housings is that they don't have the tabs to stopping you plugging them back to front.

This isn't good because if you plug in either the power or yoke connector back to front you are going to blow the chassis and maybe even the yoke also I am a bit of a perfectionist so back to the search :). Trying CPC first bought up nothing then on to RS, what a massive site! after about an hour of searching I found what I was looking for. They are made by Tyco Electronics (formerly AMP?) and still use the same part numbers used in the Hantarex manual, so why didn't a google bring up the RS page? arghh.

2way housing #280590 RS #509-1641 - used for the degaussing coil
4way housing #280591 RS #509-1657 - used for power
6way housing #280592 RS #509-1663 - used for video and yoke
crimper pins #280702-1 RS #668-9381 - used with all above

These connectors are used on MTC90/900/900e/9000 and 9110 after that came Polo which changed the power and degaussing coil connectors to molex but kept the video and yoke Tyco.
