No it is not the case that you need heated cathodes to produce X-rays, and many of the early X-ray tubes were 'cold cathode'. See for instance https://www.orau.org/ptp/collection/...thoderound.htm

Thanks for the information Glyn.

We sold few Bush CTV25’s and those were the early ones. The picture on the Pye/Ekco we thought was much better so we concentrated on those although we didn’t sell many of those.

Agreed - the Bush CTV25/167 didn't produce the best pictures - the reds seemed brick coloured for some reason. Although the Pye chassis became poorer as cost-cutting took effect in the Seventies, the original dual-standard and early 691 series gave very good results as did the Decca in this post, despite being a bit engineer hostile with its short interconnecting leads.
