Yeah, same as most, sticky suction pad to crt, r,g and b filtered
photocells. Ciruit looks simple enough, just a hell of a lot of pots!

Thanks to everybody that's replied so far.

I'm sure you are correct about your device...but don't jump to
conclusions
about RGB versus YCM. I spent years using (US) Greylab RGB densitometer
to
control the chemistry in reversal motion picture film processing
machines.
There was an interchangeable filter head for YCM so the same machine
could be
used for negative processing.

You can use either RGB or YMC heads, it's just a matter of knowing
your complimentaries and adjusting the dichros accordingly.

As for the Graficon the OP is talking about. Is it the type of
analyser that uses a photocell probe that reads directly off the crt
screens?
