Hi to all,
@Eidolon : I built an NTSC 3.58/USA Modulator many years ago, it's not easy (coils, etc.) a Grid-Dip meter is really handy to build them + you need to master RF circuit board grounding techniques.
I searched for you E-Bay UK/France/Germany using search words such as "PAL encoder", "RGB to PAL coder", etc. didn't find much interesting stuff, some Pro units, bulky and expensive plus of course a bunch of ICs including the ubiquitous MC1377 & more modern chips.
Found though one cheap consumer coder sold by a French guy :

I am quite astonished at the lack of choice, consumer computers & games outputting RGB which needed to connect to a television sets aerial input were galore in the 80s/90s, where did all this stuff go...
Best Regards
