Hi Astracat,
Worked on Philips G500 series at the time, where we shoved a Woolworth screwdriver in the HT interlock and tried keep our parts away from those PD500 X-rays. Bit daft maybe, as was mostly the LOPT overwind gone S/C.
Loved most of the films, especially 'The Home Made Car' and 'Atlantic Parks' as featured a tasty gal. The first is now available in perfect quality on a composite DVD of BP stuff of the period. 'Atlantic Parks' only available on YouTube in crap quality, where its all colour and no luminance. Recall it was a 'Film Board of Canada' film, but they don't seem to have it listed - Sad.
Later a bench tech for another firm who sensibly didn't do Philips, Pye or the hybrid 'Burning Bush' which seemed to have shop burning issues if left on overnight - Used to light my fags using a Ferguson 'jelly pot' LOPT as 7.5Kv was just the biz to get one going. Memorable fun when I tried re-light one after lunch, forgetting it might be a bit damp - Chris.
Said BP disc also has 'Sky-hook' and 'Proserpina' (Italian with sub-titles) Sadly when I copied it, the sub-titles vanished for some reason, but seem to remember how it went.
