A Thorn 9001 22" set, made by Mitsubishi probably in the late 70s. It's was amongst a load of furniture from a deceased estate. It's in decent condition. There are a few chips in the plastic here and there, but the internal antennas are intact.

Its working as found with a reasonable picture. It is lacking contrast and the contrast control doesn't seem to make much difference.
As expected the tuner needs cleaning and the channel number bulbs are out.

It doesn't look like it has ever been serviced. Hopefully changing some suspicious looking caps on the video board will improve the contrast. This will be the first set I've worked on in ages that has a conventional transformer power supply and an actual steel chassis rather than a couple of PCBs held in a plastic frame.
