The 9001 miniature valve is a sharp cut-off UHF pentode. Essentially this is the 954 acorn valve on a B7G base.

The high frequency of operation is possible without a co-axial construction mainly due to the very small size of the electrode system.

The thin glass tube envelope is 18 mm in diameter and, excluding the B7G base pins, is 37 mm tall.

References: Data-sheet & ³⁰⁰². Type 9001 was first introduced in 1943. See also 1943 adverts.
