Perhaps I should start by saying that the tasks to be undertaken
on this page are not for those of you without electrical and soldering skills,
but for the competent, the following circuit will give a quality picture and
mono sound through a television set from a ZX Spectrum +3 or a +2A. The lead
was designed by Alan Cox and has been built and tested by a number of different
people (including myself) on a number of different makes of TV (with almost
complete success).
Should you build one of these leads kindly report the results so we may judge the success rate.
From feedback received it would appear that this lead will not work with most
of the TV/Video Combo units -- not surprising as most are of cheap manufacture
with the minimum of components.
Info added April 2007:- Do note that this lead was designed some 5 years ago and many modern TV's do not have the required connections on their Scart sockets to enable this lead to work!

Just in case it is not obvious, use the six core cable to connect the DIN plug video/RGB connections to the Scart plug and the single screened cable is for the sound connections to the Scart Plug - centre of cable between pins 2 and 6 on the Scart plug and pin 3 on the Din plug, the screening goes between pins 4, 5, 9, 13, 17 and 18 on the Scart plug and pin 2 on the Din plug. Once the Scart lead has been made up following the above diagram, tape the two leads together (or use cable ties). With both the TV and +3 switched off plug in your lead, then switch on the two machines and test.
Alan Cox offers a plain English way to produce the lead and could be preferred to my circuit diagram.It is well worth the effort of making up a Scart lead for your +3 or +2A machines, as the quality of picture (the sound remains mono) far exceeds that obtained from a Black/White, Green, Amber or Colour Monitor. Games are given a new meaning when played using a 32 inch wide screen Television.
NB Due to the nature of Television design there is a possibility that the lead will not work on every make and model of TV sold throughout the world, try the external Scart socket offering to handle CVBS, RGB and Y/C first.
