We can modify your Spectrum 16K/48K/+ to use composite video instead of RF (aerial). Because the modification simply involves routing directly to the video output - by-passing the modulator innards - there are
no external changes to your Spectrum - you just plug in the supplied phono lead to your Spectrum and your television's "video in" port.
Just send us your Spectrum on its own and you'll have it back in a few days (1st class recorded postage is, of course, included), with a better video display than you've seen before.
If the display is still less than it should be, we can at no extra charge change the electrolytic capacitors and the power regulator, as these parts have mostly aged and now cause interference.
Please note there is no reason to do this on a 128K or later because these have monitor outputs already.
