About 30 years ago we had a hobbyist electronics shop chain called Maplin, who produced and sold their own range of kits, many of them very good. When NICAM stereo TV sound was introduced in the UK, they produced a kit to decode the NICAM signal to audio. In fact it was a total of 3 kits -- the NICAM decoder board, a TV tuner/IF strip to feed it (if you didn't want to try to tap off the NICAM subcarrier from your existing TV 's tuner), and the case/connectors/tuner channel memory/etc.. I built the entire system for my parents who had a VCR [1] that could record stereo sound from line-level inputs but which pre-dated NICAM. I then realised that the tuner/IF board on its own, with a multi-turn pot added for tuning (rather than the remote control/memory control IC used in the full unit) would be ideal for turning the RF output of UK home computers into composite video. So I built a second tuner board for that. Still have it, still use it. -tony
