SHMBO asked for a bread maker... upon searching on Freegle for one I could not resist typing in 'TV' in the search box to see what may turn up. A few hours later, instead of a bread maker, I had a nice 14 inch black and white set which is a worker in excellent cosmetic condition
. The previous owner bought it new when she got married and used it as a main set for a short while. The code G8-40 on the back (I think) denotes 1978 week 40.
The contrast and brightness sliders are stiff and notchy and got a blast of servisol. From what I could find, this set has the 1690/1 chassis. While I got the back off, what preventative maintenance should I consider? I heard the EHT diode can short but this set for now seem to be OK. No signs of distressed components (bulging electrolytics or toasted resistors) or any repairs can be found which bodes well.
The Mullard tube, an A34-510W appears to be made in Taiwan which was a bit of a surprise. The Sun was setting on the UK TV manufacturing industry it seems by then.
