Hi
Keep an eye open on ebay - there were some NOS Mullards a few weeks ago.
The Sylvania CRTs were mainly fitted to sets badged Telefunken (the one with the odd 7-flap varicap tuner) - probably that's why you didn't come across them, Simon - lucky you! This was towards the end of the chassis production run but before the final 'blackfronts'.
I thought the tubes were Hungarian, but I might be wrong. American suggests RCA, not noted for longevity.
Not sure if I should admit this, but I used to find disconnecting each cathode and grounding it via a medium value resistor briefly would result in a brilliant colour on screen, each of the same intensity on a good tube. A bit brutal, I admit, but it served as a pretty good way of determining a duff tube, especially in the field!
