Re: Which was the worst TV set / chassis you had to repair
I think the basic problem with UK designed and made sets was using the cheapest possible components.
In particular, using Erie carbon composition printed circuit mount resistors, which tended to drift in value (especially in higher voltage parts of the TV's circuit) or didn't have a high enough power rating.
Then there were those plastic/resin cased TCC Elkomold and Callins electrolytic capacitors with short life spans - possibly due to the heat in a valve TV.
At least the mainland Europe made TVs I used to work on in the 1970s used carbon film resistors and better quality electrolytics.
The difference between mainland European and UK TV purchasers was that the UK ones were driven by the lowest price, rather than quality. This might be due to the UK having a lot more TVs out on rental, rather than bought outright....?
The only major UK TV manufacturer that made the reliability and quality grade (eventually) was Thorn EMI Ferguson, but they were too late in making the change (TX9, 10, 90 & 100) and were sold to Thomson in 1987. That didn't end well either, did it? Even Philips had to throw in the towel - eventually.
