There were various versions, I think, using valves with different bases
but which were electically similar. The 12BE6/12BA6/12AT6/50B5/35W4 were
7 pin miniatures (B7G base in the UK). IIRC the octal line-up was
12(S)K8/12(S)K7/12(S)Q7/50L6/35Z4??? The 12K8, etc had top cap
connections, the 12SK8 etc were 'single ended' and had all connections
made through base pins.

were the 12ba6, 12be6,
35w4, 50b5 and the 12at6. British and Euro names for the same tubes could be
