Thanks Hommer J, back in the day when you had great design and quality control TVs worked, they took a great deal of care in the RF sections, now it's all compressed digital bullshit and the tuner is a postage stamp sized piece of Silicon. With an indoor antenna I can't get reliable reception from a transmitter that is less than 10 miles away, OK so there is a tree in the way but it's still line of sight.

I wonder what people then would think if told that you could watch TV on your phone. They would probably call you a delusional nuttera,

I cannot remember when I started doing it but as a kid I used to take the back off the TV set and break something, that way I got to see the TV repair man at work. Yes, I was aware of the EHT but it still brings a shiver down the spine now when I think about what I did. Sets then (early 1970's) used lots of tubes and were built across four or five PCB 'panels' that were arranged either horizontally or vertically around the CRT.

I think the repair engineers finally realized what was going on because within a week or so two things happened, a) the back was secured using security screws and b) one of the engineers delivered a scrap TV chassis for me to play around with. I suspect that the Service Manager believed in the philosophy of 'start 'em young'.

Good shots of tube production. I especially liked the Welch 1400 pumps evacuating the test 6AR8 tube. The sound they used was of a pump sucking air. Normally once a good seal is established they are quiet and you don't hear the gurgling sound. Also good shot of the induction coil.
