I was confused before i got those tubes,why there's a additional getter supporter with no getter on it in telefunken ecc801s .after i got those early version ecc801s i came to understand that it's a evolution remains.just like human's caudal

ok,I checked.it's made by mullard around 1956

The top mica had more edges which can be seen on older Mullard ECC81,82,the typical Mullard square getter and I'm not trust the printed.
