I have 12 of these tubes for a future project, so I am very interested in seeing this work. Do you have any details which pin numbers on the 3L01I are connected to the circuit ? I think the voltage for focusing needs to be adjusted.
Does the size or shape of the "dot" change when R43 or R44 are varied ?
