Amiga RGB analog to component Y-Pb-PrTV ?

[Framiga]

not sure what you are asking about "electrically compatible with the Amiga's analog signal", anyway...

Conversion from analogic RGB+CSync to Y-Pb-Pr is not a matter of "few components and some resistors" and an equation (as you can see in a pic from that site)

Do you see how many components are required? (just to get the idea) impedance compensation, op- amp right PCB design/routing (to avoid intenference/diaphony reflections etc.

It costs too much? naaaa! you can spare something doing it by yourself? mhhh...prepare you to a great disappointment ;-)

"I am familiar with impedance compensation and correction. I am familiar with PCB design as I regularly use Altium DXP. Interferences and diaphony reflections may proove to be a problem but that remains to be seen."

sorry but ... why ask over here if you already know it?

edited- just noticed that the above link is for a VGA to Y-Pb-PrTV  (to no use for your needs)

or better ... you could attempt this way:

look for an AmigaRGB to VGA commodore adapter and the above mentioned VGA to Y-Pb-PrTV transcoder. It should works seen that frequwncies doesn't matters in this scenario.

How well it will works, "remains to be see" ;-) but if you have time and skills it worth a try.
