400 mA (!)

This is likely a one-off project. I had room left on a PCB order and had a tube lying around and was curious as to whether it was possible or not. It is, but is rough and loses a lot of output. I don’t know when I’ll get around to updating the circuit so the limited remaining PCBs are available here first-come-first-serve for adventurous tinkerers.
Consumes about 400mA from +12V. The tube and the filament regulator get very hot in operation.
Instructions and BOM here soon…
