    The only basic difference between PAL B and PAL I that will cause you any
    trouble, is the sound spacing, +5.5MHz for PAL B, and +6.0MHz for UK PAL I.

    With most TV's and VCR's, it is only necessary to locate the sound
    intercarrier 5.5 meg filter ( usually a 3 legged device that's either matt
    buff colour, or shiny blue, and looks like a small polyester cap ) and
    replace it with a similar 6 meg type. You can usually cull one from an old
    scrap chassis. They normally have either " 5.5 " or " 6.0 " printed on the
    side of them. Once you have replaced the filter, you normally need to
    slightly retune the demodulator coil ( assuming that it has one ). Used to
    do quite a few, but haven't recently. As far as I know though, the sound IF
    strip hasn't changed any.
