      Hello again.

      I’m just about ready to install the SNES RGB amp but I have 2 concerns.

      1. How is the 1-chip brightness fix setup? I have read in the instructions that I can solder resistors to the RGB amp pads RR, RB and RG. However I’m just not entirely sure if I have the correct idea. I would appreciate if someone could look at the photo I have posted and tell me if I would be doing this correctly.

      2. I am concerned my SNES RGB amp might have a production flaw. I have not done any soldering at all yet. It arrived with some sort of a copper wire looking material that seems to be touching several components. I will upload a photo of that as well. Can someone please let me know if this is a production flaw or if this is normal? I am concerned it could cause damage to my system if there is a possible short circuit.

      That’s all for now. Thank you!

      My setup is:
      SNES 1-Chip-02
      Multi-out to scart that plugs into OSSC
      OSSC HDMI out to HDMI to VGA converter to PC CRT

        Hi
        Over to my friend to answer point 1:-

        1. Yes that the right idea, just use some 0603 SMD resistors. Unfortunately without an oscilloscope there is no sure way to know that correct value as each SNES console can be different but most people just put 750ohm resistors in there and hope for the best.

        2. That’s nothing to worry about, it’s just some flux residue left over from the reflow process. You can clean it off if you like with some flux remover solution but it won’t cause any problems if you leave it there.

          Once again thanks to you and your friend for the help.

          This was all I needed. I went ahead and did the installation and it seems to have gone great! The picture quality is just what I was hoping for. I’m very happy with the results!!

          Thank you!!!
