Default Re: Stella ST1007U

Powered up the Stella today without the CRT. After a bit of fiddling about with the line timebase we have a very healthy spark at the EHT connector. I reckon there's 15KV there. The line output valve was a Mazda PL36 but somehow the set didn't work properly with this valve so a Mullard PL36 is now being used, the correct make for a Philips TV of course. For the next stage of the restoration I'll turn my attention to the frame timebase.

Attachments show that the Mazda PL36 is a late production type and has the electrode structure of the cavitrap PL504.
