I was looking through an old copy of Seely's book. My favorite tube
(on the basis of clever design) was the Phantastron. Really slick.

One washer had a brush where it ran the water through into the wash tub. It seemed to work well.

Brilliant use of a tube designed for a different purpose. They were used as
the ramp generator for horizontal sweep in oscilloscopes. Likely used in
radars as well.

Yes it was. For a fascinating and informative reading of foundational radar technology, one might want to look at the books that came out of the MIT Rad Lab. PDFs can be found here:

Being a long time student of control theory, I looked at vol 25, Theory of Servomechanisms. The treatment of the theory is clear and complete and I was astounded to realize that my first control theory text book (affectionately
paraphrased to "Dazzled and Hopeless" - I cant remember the actually spelling of the authors last names), contained almost a verbatim copy of the servomechanism volume. ahhh, the good times...
