Re: Mystery Decca (CZ8150)
The neck on this tube is 38 mm.
I've found something interesting in this book:
Liberal Trade and Japan: The Incompatibility Issue
Contributions to Economics
Author: Marcel F. van Marion
Publisher: Physica-Verlag
Date: 1993
P175 gives a hint at the complex relationship between the UK government, Rank, Toshiba and Philips/Mullard. It seems that Toshiba wanted to buy the 30AX technology from Philips via Mullard, but were frustrated? It looks to me like they just copied it - at least experimentally. I think that this experimental tube bears witness to some interesting 'goings on' in the UK TV industry of the time!
Thanks, Robin, I had seen reference to 150V for the 110 and that tallies with your information. However, at 150V the width and range of E-W pincushion is inadequate. At 165V the E-W pincushion is not clipped and there's enough width. It seems happy there.
This set is a mongrel - looks like the CZ8150 but has teletext and a Toshiba '30AX'. No wonder there's no identification of any kind!
Best regards,
Paul M
