that valve is a high-gm pentode( or perhaps a beam tetrode, I can't see all the grid posts to determine if it has a supressor grid or beam plates ). I think it goes by E180F as well.

The D3a is another. High mu triode connected too. Not exactly a common valve in the States though.

Don't worry about the sauce, it's not tooo spicy.
regards,
Douglas
