    Default LumaFix64 Jr

    LumaFix64 Jr

    The LumaFix64 Jr (Junior) is a low profile and compact version of LumaFix*. The concept and name are used with permission from e5frog.

    This version adds only about 4mm height (socket to socket) and makes more room for a heatsink (which is a tight fit in the C64C).
    Each unit is assembled by hand and features high quality Bourns potentiometers.

    Please note that it does NOT have the Chroma adjust due to design limitations. Most S-video cables have this (~300 ohm inline resistor for chroma signal) already though.

    *LumaFix removes/reduces the vertical lines/bars in the display and is a pretty well-known way to improve your C64 picture.

    Availability: 3 unit(s)










    Price: €16 each
    International untracked shipping: €3
    Payment via PayPal as gift

    Thanks for looking!

    The boards are also sold elsewhere.

    I have question, my C64 is connected from the vga port of C64 to the scart of the TV, can I use it to improve the picture of my C64 or I will buy a S-Video cable?

    Hi, I guess you mean A/V-port with VGA port. There are two common picture interference problems:

    1) Color bleeding/checkered pattern - too strong chroma signal. Many C64 S-video cables features an inline resistor to dampen the chroma level.

    2) Vertical lines/bars - AEC and PHI0 clock signals from the VICII cause these lines.

    This version of LumaFix will only fix the second problem with vertical lines. What kind of interference do you have?
