First flat-faced CRT?

[Alastair E]

In the very late 60's, early 70's the Russian Co, Mashpriborintorg (sp) released to the UK market a 6" B/W portable under the Rigonda name that had a flat faced CRT....
The set was all transistorised--with weird Russian transistors, very well constructed for what they were, and had an EHT doubler, run from this odd sealed flyback transformer.
The sets had issues with flyback transformers and the field-timebase stages.

These sets were sorta given away with tokens from Corn-Flakes as I recall, and when working correctly gave a fairly decent picture, although appeared to be dished inwards--probably as we were all used to seeing pictures on goldfish bowls at the time!

Here's one Ive found on ebay--Nothing to do with me BTW.....
