It was the valve ones from the mid to late 60's that were both seriously 
expensive and unreliable. So much so that most people at the time rented 
them since then routine service and repair was included. Enough money 
was made on the TV rental business to fund a new Cambridge college.

There were others in the same white goods and TV rental business and 
several of the founders were big charity donors and philanthropists.

Valve sets ran hot and somehow valves would gradually work themselves 
out of sockets or just plain and simple fail at switch on. I saw one or 
two very old all valve sets survive into the 80's that kept the valve 
filaments warm continuously even when the set was nominally off.
