I did my mod how you did it, but there were some issues with the video being out of spec (wavy lines, colors off). Only with a handful of games though. I then matched what they did in the website you linked and everything worked fine. I think the resistor values need to be spot-on (120 and 200 ohm), and the 120 ohm needs to come after the capacitor on the output with a jumper put next to the 200 ohm.
Thanks for the feedback. Interesting that you had a colour issue. I don’t believe I ever saw a problem related to that, but I’ve only got a small assortment of games. As for the so called “jailbars”, I never fully got rid of that. So I might crack it open again one day and tweak things further. Could very well be an impedance issue
@@burntoutelectronics Why not have bout RF and AV :) ? I do the same MOD scheme ,but do not disable the RF modulator. And to avoid cutting the shell, I just removed the channel selector switch like you and put stereo jack for the AV :) And repurposed the TV/GAME switch to turn off the second's controller microphone :) drive.google.com/file/d/1R_Yuq2Pej_lxOj9XRiIk3PoIdSxwXn_2/view?usp=share_link
@@intel386DX There is two reasons why I did it the way I did: 1. I changed the impedance of the buffer transistor that’s connected to the video output, so keeping the RF out and AV out connected might cause impedance issues, or worse still, it would’ve had too much or too little signal drive into the RF modulator. 2. Everything I own isn’t equiped to work with NTSC-J TV, so it would be pointless in my case to keep around. True that I could’ve done a 3.5mm jack mod, but I prefer the look of two RCA jacks. It’s still sleek enough and unobtrusive to the consoles original design
@@burntoutelectronics if you connect the RF portion after the AV mod it will be not interference :) But in your case you can not test it due to lack of compatible TV .
Mine has a scrolling statically line and i dont know why do you know what could be causing it?

Nice! I usually prefer to keep the RF functionality.
That’s fair enough, if you’ve got something that can easily display the RF output why not? For me it’s far more convenient to have AV video

@@intel386DX can you explain the microphone switch in more detail? thank you
Jail bars?
Is there a way to brighten up the picture, mine comes through dark
