Re: Earliest BBC2 Sets?
Just out of interest - were any UK TVs ever equipped with Nuvistor front-ends?
I rather suspect not - by the time UHF TV became anything more than a curiosity here the world had moved on to transistors and was focussing on the likes of the AF139/239 and Texas Instruments' GM0290.
(One place I'd have expected to see Nuvistors used was VHF/UHF mobile-radio transceivers - but none of the Pye/Storno/Ericsson/Siemens/Marconi/Philips/GEC stuff I ever worked on used them)
