In my post scheme, 4 points take directly from tia and 2 point you choose way to take from tia or from resistors which you can find trace from tia pins.

Greatings from Ukraine. I try few mods, and finaly find solution. I do next mod on my Atari 2600 clone and it work. Point You must take colour (chroma) and not directly from Tia, I mark points red. Or, if You want, take it from Tia but You must repeat part of original sheme (mark blue).
