I have a Sony KV 1320UB that has a 3AT2 EHT Rec in it, and I also have the externally identical KV 1330UB that doesnt!
They are both from '70/71 ish....
Very last set I saw in a shop new that had valves was in 1981 --It was an old stock item, a 22" ITT CVC-9 hybrid colour set, --although that make/model will probably be meaningless to a lot of you.....
I wish I had bought it now and stored it away!
