RF/IF amplifier, EF41 rebased to 9-pin noval. Part of the Innoval family, early noval tubes with frit-seal base sealing to envelope, first introduced by Philips Australia.

This tube was introduced in 1951, to extend the Innoval line to FM radio sets.

Quite unusual, this Philips tube does not have any European equivalent. It was only made for the Australian market.
