While it was under warranty, service people seemed to arrive monthly. When it was out of warranty I learned a lot about the practical side of electronics. Eventually it ran reasonably reliably until the picture tube gave up so my father and myself replaced the A66-140X https://www.google.com/search?q=beovision+3400+pdf I don't think the UK ever had any tube only colour TVs, they were all hybrids (tubes for high power / high voltage) and semiconductors. In the above case all discrete except for one integrated circuit (line oscillator).
