Oh yes - the glass was metallised on the inside and the outside to form the EHT smoothing capacitor, and the EHT went in via a large press-stud on the side - due to a problem the CRT kathodes went cold before the EHT o the anode ran down, then the tube remained a fully charged capacitor with the voltage accessible to the careless thumb if you were changing a defective tube.

I recall getting a shock to my hand and dropping one, luckily flat on the face, so it survived with no implosion. Still a very sharp intake of breath moment. Plenty of black and white dual standard sets sold from mid 60s  up to the early  70s, as for quite a while not all the channels were available on UHF in all areas of the UK. As old bangers a few of these were still going ten years later, and some crossed my path as repair projects. Pre printed circuit TV repair was something else, to keep cost down as many  components as could be just  strung between the valve  holders,   a bit like this, but grubbier   and simple paxolin tag solder strips  this stuff  where they could not. By modern standards very poor thermal management, so when they got full of fluff a fire was not unknown.
