How to convert VCR Philips VR 451/59 from PAL BG/DK to British PAL/I ?

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.
