Yes, they are the same but what surprised me is the Mitcham made them in 1958 ( R8C ) instead of Blackburn made in 1955( B5E ) and the B7x version were already change to ring getter.

sound different?

sound different?

Not much,the R8B version sounds more dynamic and the B version have a slight smooth mid range and a little darker, I like the R8B version which sounds more lively and better transient.

that make sense.I always think W better than R and R better than B

I have so many Mullard ECC82 valves may be it's time to test the R and B double support ring getter version.

I haven't seen any Black Plate Mullard ECC81 yet,the earliest 1552 I had is L3 date code (somewhere in the house but still can't find it ) I also have a 1552 D4 which I believed have the same structure of the L3 version,will post here when find them.So,I think the earliest Mullard ECC81 was made in 1953.

My friend have a 1552 K3, that is 1953.11
But it is strange why no earlier production exist
Normally ecc81 is produced earlier than ecc82/ecc83

It may be Mullard only used Long Black Plates and never use short black plate on their  ECC81
