Had to take my TV22 MKII out of the case today to replace a crackly audio o/p transformer (a shorted turn I suspect) and took the opportunity of reducing R52 (R55 in the MKII) to 10k. I really couldn't see any difference, except the picture made a slight twitch as I did it.

Anyway, I think the picture is probably as good as the TV22 gets. I'm lucky with the tube, although it does need a slight refocussing after the first 30 mins or so.

Rather a nice set, and MUCH easier to work on the the TV24!
