Hi.
When I started in the trade in 1970 as an apprentice CRT changing was common place. In my first company (British Relay) we handled a lot of Murphy sets. Even then there were a lot of V310, 410, 510 & 659s out on rental. If the customer was happy with the set a regun tube was fitted from Renvu Tubes in Renfrew.
Many of them were on the original CRT not bad for up to 12 years of most likely hard use.
After 1955 we had two channels in the UK so with more choice the sets were used more often. BBC2 started in 1964 on 625 lines but many customers wanted to hold onto their 405 line only sets even into the early 70's, a lot didn't like the choice of programmes on BBC2 and being in Scotland wouldn't waste money on something that would hardly be used. Things did change when later our local transmitter opened improving the UHF signal, by 1974/5 there were very few 405 line sets in service.
