The PP6E is an indirectly-heated output pentode. The image above is incorrectly labelled due to part of the lettering having been wiped off. The PP6E is quite powerful, and one of only a small number of 6.3V types on B7 bases.
The classic envelope is 47 mm in diameter and, excluding the B7 base pins, is 117 mm tall.
