ITT-KB were perhaps the most reactionary of CTV makers. Their CVC1 was the only hand wired CTV sold in the UK. By 1976 Philips, Thorn and RBM had been solid state for several years.
Did B&O have some late hybrids?
It was a bold move by Thorn to reject the Mullard/Philips hybrid reference CTV design and plough their own path. Probably driven by their massive presence in the rental market which demanded sets that were easy to service in the field. I don't think any other 1st generation CTV had readily swappable modules. They were aligned on jigs at the factory and so needed minimum adjustment after field replacement. By contrast, transistors almost sneaked into monochrome sets in the early 1960s. Portables were an obvious target. Full size monochrome stayed hybrid more or less unitl the end. The fairly rare Thorn 1600 was an exception. Did anyone else make a full size solid state monochrome set?
