I will be shortly looking at a B&O 3400 CTV from 1974 (white cabinet). Its currently dead so hoping its saveable.
I did read a television article on these from a servicing angle, and it mentioned the line transformer is a common fault (It can't be that as I haven't got one)
Does anyone have experience on these sets and how rare are they nowadays?

Was that by any chance the article on the 3400 series by Eugene Trundle from 1980? That article among countless others are available via the "Service Dept" up top, If by chance anyone else is interested in reading them see here. 👍

Unfortunately there are two separate transformers in this set, line output and EHT and both have a potential to fail with the EHT transformer being more common. In the late 1970's I worked for a B&O dealer and saw a fair few arrive in the workshop, these can be a real challenge but well worth the effort !
if you are lucky a schematic and setting up details might still be found in an envelope inside.
Thanks for the advice. The set has been "looked" at by a non engineer in the past. I will post some pictures soon.
If the Transformer(s) are at fault, I would think the chance of finding a replacement would be almost zero!
