The 1Chip SNES outputs a way superior RGB picture than the older revisions.
I think i know why.
The early SNES used a amp which is feed to the MultiAV connector and to the encoder separately, you see that it consists of multiple bipolar transistors. And the older encoders only output Composite and S-Video which also need amplifiers.
The later models contain a modern encoder which also outputs amplified RGB, so they just used a PNP transistor because the video output of the PPU seems to be a voltage sink (but it could be another reason, or i'm wrong).
The 1Chip is very simple as the RGB output is a voltage source connected to 160ohms to ground and that's it.

I think that these transistors might be the reason why the RGB picture is slightly blurry compared to the 1chip, as bipolar transistors have a tiny parasitic capacitance which define the maximum switching frequency.

So i'm going do a experiment of installing a THS7314 (high quality RGB amp as single chip) and bypassing that transistor amps in my early PAL SNES.
The motivation behind this is that i see some chroma interference on the red channel and it's not caused by the high quality cable i made myself, so if i'm going to check the internals of my SNES then why not try this out to see if there are any improvements.

Does anyone here has other ideas or suggestions?

I didn't ordered the THS7314 yet, so don't expect it to happen within the next 2 weeks.
