The mechanical construction seems to match the more expensive Premiere advert.
I think the EL51 is the frame output amplifier, all the transformers on the chassis are iron cored and appear to be low frequency parts.
The front of the CRT is actually fitted with an implosion guard.
I dont think I'll be applying power, not least because the only EHT supply I have is on my Ekco TV.
The set caused quite a stir at the boot sale, two people I met had relations who had built TVs after the war.
One of which obny ever worked briefly and was thrown into a river in dusgust.
My uncle also built a TV and later went to to work at Philips/Mullard for much of his career.
He played an important role in my developing interest in electronics, he gave me components from time to time.
I had a few old home construction books when I was a boy and adapted the designs in them to make my own oscilloscope using a military display unit with a VCR97 tube.
There was a very good army surplus shop near where I lived and I got all sorts of stuff there - Eley's was the meeting place electronics enthusiasts on Saturday mornings.
I also buillt a flying spot scanner with a photo multiplier tube to scan a transparency and show it on a TV. it was a bit too complicated for me at the time but it - kind of - worked.
The design for this was also in an old home construction book, I wish I could have a copy of that again to check the details.
Recentley I found one of the books I used to to study, some pages are shown below:
Hi.
Interesting read. Perhaps I came across as patronizing a bit. Over the years I've seen many come and go on forums for many reasons.
I certainly now know that you will be OK with the chassis and sorry for telling you how to suck eggs.
I'll keep my eyes on the thread to see what transpires.
Good luck.
