[Zelandeth]

Been fiddling around with this set some more.

Replaced quite a few of the caps now (which is proving somewhat fiddly due to the replacements being somewhat larger than expected (if/once the set is running to an acceptable level they may get re-replaced in some cases with caps of a slightly more sensible voltage rating). This was due to RS being out of stock of the closest equivialant values, so these being significantly overrated in terms of voltages. By orders of magnitude in some cases!

I haven't actually re-taken any of the voltage readings yet, but can state that the set is running rather a lot better in terms of stability. The horizontal and vertical hold controls generally had to be juggled every time the set was switched on in the past to get the picture to lock, and now and again when tuning into stations - I've not had to do that once today.

One thing I have noticed is that the contrast seems to "flicker" quite a lot (the control isn't the culpret), the black level seems to be pretty constant, but the brightness of light areas of the screen varies a lot from moment to moment. Not sure if this is symptomatic of a tube fault, or if it's just something like a duff cap I've not found yet.

I have noted that the line whistle seems to be rather quieter, and that the PL36 seems to be running a lot cooler now - though I'd not bet money on that being true.

Panel lamps are going to require a little more digging than I had hoped, as all the bulbs are 8v .3A examples, as they should be. Is probably a duff thermistor, but I'll have to find it first.
