Easy trick to improve a little bit the video quality for the C64

Cut the resistor

Easy trick to improve a little bit the video quality for the Commodore 64.

The fix can be made without removing the modulator. Obviously the RF output doesn’t work anymore.

    Is it just a matter of disconnecting that resistor? How much does the image quality improve? Do you have pictures of a monitor connected to the video port of a modded C64, before and after the mod? Thanks.

    Hi Cercamon, the image improve very little , just a little more clean.

    I use only SVIDEO output.

    The article where i have found this mod with a different version of the modulator is here:

    Thanks for the article – I have an NTSC C64c and read over this article and a few others. Took a chance and disconnected the L2 on the RF modulator, and saw a little bit of brightness and color return to the s-video signal (just a slight change, but noticable) and remove a little bit of the “noise” on the screen. Good stuff.
