With Mullard the etched type and date code is where to look. You have to learn to read them and be able to identify construction types. Some great info here. I don’t know their ECC82s well (I’ve way more experience of the ECC83 of which I have 15-20 or so of different vintages from 50s long-plates onwards). The Mullard ECC82s I tried in the PL were fairly late (early 70s I think, not even sure they were Blackburn factory) and were nothing special (rather warm and soggy, as they tended to be by that point).
thanks for the link. Yes, my first set of Mullards, I bought entirely blind were so soggy and muggy, I was thoroughly disappointed.
The ones I got from Watford seem to be the best I have tried, they are marked as CV4003, KQDD/K, 83/09
