Re: Televisions
I think my first colour set arrived in 1971. It was rented from Radio Rentals in Bristol and broke down so often the engineer used to call in if he was passing to see if it was still up and running. About £7 a month rental if I recall correctly.

The originator of Robinson Rentals (a similar operation to Radio Rentals) funded a new swimming pool at Bedford:- https://www.bbc.co.uk/news/uk-england-b ... s-50260186 as well as a new college at Cambridge:- https://en.wikipedia.org/wiki/Robinson_ ... ge#History and a maternity hospital:- Rosie Hospital

Re: Televisions
The success of companies like Radio Rentals was down to the fact that TVs broke down so often (blown valves mainly) that it was silly to buy one. I well remember getting the heebie-jeebies when I shelled out my hard earned to actually buy one!

Re: Televisions
No you mentioned the TV rentals, I remember contributing to the rent of a TV set in mid 90's while at the University. A very convenient solution particularly as we didn't have to pack the TV at the end of the year.

Re: Televisions
That's why I bought the workshop manual.
Being able to understand it also helped.
Just found this.
The 22" screen is smaller that the 23" ones that I have on my PC! and I have 2 of them.

Re: Televisions
We got ours in 1974. It had a magnificent real wood case and easily the match for radiograms of the day. I think it might have been a Baird. I can't remember its replacement but our repair man in Nairn would give me a bundle of valves and I would swap out valves until I got it working reliably. I think the weakness was the valve heaters.CharlieOneSix wrote: ↑Mon Dec 09, 2019 11:23 pmI think my first colour set arrived in 1971.

I can't remember bringing it back to England but I know we had to get a bigger set as our new lounge was larger.

Re: Televisions
Back in the day when I worked for Sony, there was a 40 inch tv available, but it could only be moved using a forklift truck
When all else fails, read the instructions.
Re: Televisions
When the transistor took over from the valve, it was cheaper to upgrade because the old valve TVs could take a couple of kW and the saving in running costs would quickly pay for the new, lower power TV. If you had electric heating it probably made no overall difference to your energy bill, but I suspect everyone else started spending more on heating when they upgraded.
Re: Televisions
Before we were rich enough to afford a TV at our dump, grandpa Slasher used to listen to our short wave radiogram after dinna which also played 78s. He liked listening to VOA and the BBC Int’l.

Re: Televisions
Interesting use of an old CRT to make an oscilloscope

Re: Televisions
Standard A level physics experiment using a CRT as an oscilloscope. I used to have one for the purpose, but after local state schools lost all their physics teachers who were actually qualified in physics, their replacements stopped using them - "Oh, 5,000 Volts! Scary!" - and they started giving them away. At one school I ended up with 9 of them! This meant one between two and my students could do their own experiments rather than just helping with the demo.

Re: Televisions
We need to make a reference on how 24'' (a normal TV in the 70-80's) become good only for computer monitors or for very small spaces like a kitchen and mainstream TV sets start at 32''

Re: Televisions
Back in my old school lab there was a plethora of tubes, from CRT's to the more basic Crookes tubes , the latter, which if misused by supplying a voltage over 5000 would also produce x-rays. Much fun was had by all. Nobody in my class died or has subsequently died due to their tube "adventures" to my knowledge.Fox3WheresMyBanana wrote: ↑Wed Dec 11, 2019 1:37 amStandard A level physics experiment using a CRT as an oscilloscope.

With the advent of the BBC Micro, the oscilloscope experiment could be driven by programming the oscillator and passing the outputs to the TV. Safer and more of a programming exercise than anything else.

Just wait til we get onto the fun that can be had with thermionic diodes...

Re: Televisions
I built an oscilloscope back in about 1982. I made the case for it in my school metalwork class, useful exercise in bending sheet metal. I still have it, and one day I'll get around to switching it on again, but I want to reform the big electrolytic capacitors first. Used a 3BP1 CRT.
