The posts in the scope/CRT review index are from quite e a while ago.
I have two square CRT tubes with all the high voltage gear laying around.
Does anyone know of a reliable, modern design, or has anyone one working ?

What are the tube types? You might try someone like "Cathode Corner", or if you want a real challenge, the ESP32 nowadays is fast enough and has enough DACs to drive a scope tube directly.
