QUAD FM3 Tuner - Repair and Demo

This QUAD tuner is part of my friend's estate. On checking it over, I found it worked, but the 'Mute Threshold' pre-set pot, tuning indicator lights and 'Stereo' light were not working. I replaced the bulbs with LEDs/series resistors and the pre-set pot with a new part. I then found that the 'Stereo' indicator was not working correctly - adjusting the pilot tone to the correct frequency of 19KHz fixed that issue. The tuner is now working well.
