One all transistor TV set that doesn't seem to arouse any great interest is the Pye TT1 of 1960 and yet we have here a portable TV with a full size 14" CRT. This set has an internal NiCad rechargeable battery pack which will give up to two hours viewing. The line output stage employs a pair of Texas 2G221 transistors in a stacked arrangement similar to what we see in the BRC 2000.
I was always of the opinion that CRT was a special Cathodeon tube having a gun assembly with a high slope characteristic, in fact the C14/3A is an equivalent to the Mullard AW36-20. The video amplifier delivers 30volts P - P of video to the CRT. Just enough picture contrast.
