Va max, both sections <250; Pout 4.5W at Va=250V and Ia = 52mA.

There is also a 6pin version in literature. But the basing diagrams for that version are somehow erroneous in different ways. Only the 5pin data in Babani appear conclusive and convincing. And the picture seen at the 295 shows a 5pin tube as well.
