Hi Tony,
What a great story: It's hard to believe that there was a time when these things were only a few years old. Mind you, there was a time when I was only a few years old!
John (Heatercathodeshort) commented that frame timebase faults were common very early on in these sets live's. Hardly surprising when you look at where they put it- right on the top rail of the chassis and directly behind the huge mains dropper The chassis rail itself is only 1/2 inch from the cabinet top so there was no air flow. The poor Hunts capacitors must have been boiled to death pretty quick!!
This has been a fascinating chassis to rebuild for many reasons, partly due to the bizarre layout of the components- you have to ask the question ' why on earth did they do it like that'! Surely with a bit of thought, they could have done a much better job both in terms of ease of assembly and reliability!
How well the actual circuitry will perform remains to be seen- some of that is also a bit strange.
I love hearing people's personal memories of these sets from when they were still current- it makes the process of bringing one back to life somehow more 'real'.
Cheers
Nick
