The magic eye project is nearing completion. My little op amp preamp circuit works like a charm for driving the tube from line level. I have a couple of parts on order, but once everything arrives it should all come together very quickly.

So I ordered a batch of IN-9 neon bargraph indicators so I can iterate the design with yet another variety of obsolete communist vacuum tubes.
