Anyone have any experience with this one? Theyre not super expensive, and look interesting as a driver....

It does have a weird heater voltage, 20 V. But it looks like it’s built like a tank, I guess that’s a western electric thing.
I’d be interested to see what some triode curves would look like…
The beam forming plates are interesting, they are triangle shaped…
I picked up a matched pair for not so much money a while ago, apparently they’re made for use in switchboard amplification, the data sheet says Audio amplification where voltage is limited, you can even run them on 45 V. But the data sheet shows up to 125 I believe.

The grids are wound in a sort of flattened oval similar to a 6V6, and the heater is threaded in a ceramic block like some Bendix tubes….
The Cathode looks quite large for what the data sheet says about its performance.
