If you spot the schematic of the same model that you own in " Stereo Version " , you could possibly add the missing parts.
Most of the times they use the same PCB with lesser components , at the Mono version.
You could use the tuner from an old VCR. That should have a stereo output.
Your response puzzles me. Are stereo VCRs unique to the U.S.A.?Only if it was a stereo VCR
But he's still not mentioned where he lives, the American system isn't any use to the rest of the world anyway.

The system compatibility as PAL & NTSC , its not our interest for the moment.
Technically its just an crystal that are deferent (sound) , so to operate on either system.
I understand there are numerous TV standards. But my original reply was somewhat generic. I suggested using an old VCR as a tuner without specifying its origin. But Nigel's reply implied that stereo VCRs were only used in the U.S.A. Thus my question.No, but TV standards are different in different countries, so any American VCR is likely to be useless in Europe.
I don't think that TV with analogue stereo was ever used in the UK. NICAM stereo is a digital stereo audio system on analogue TV.
I've got a portable CRT telly that I bought in France. I had to change the audio subcarrier filter to get it to work here in the UK, even though I had checked that it had a PAL option, when it used SECAM in France. I think that the PAL was set for Germany. So that's 3 different standards, in an area not much bigger than Texas. America uses NTSC which is different again.

Which brings up another point. Don't the digital tuner adapters, which will be required for all old analog sets once the switch is off, provide a stereo output?No, but mono VCR's are commonplace as well - the UK uses the high quality NICAM digital stereo, on both TV's and VCR's (or 'did', as analogue switch off is under way).

Yes they do, but not much help feeding a mono TV![]()
If the digital tuner has a SCART output, you could easily wire the left and right audio to a stereo amplifier of your choice, turn the volume down on the TV, and you have stereo sound.
