Hi peoples!
I need some quality schematic or circuit Magic eye with em80 or em81 tube.
thank you!

I made this magic eye with em80, but em80 poorly shines😕🙄. What can be the problem?
thank you!

What is the voltage on the anode (pin 9)?

What is the voltage on the anode (pin 9)?

B(9)+=245Vdc😉
Here's schematic a power supply:

How bright do you expect it to be? Did you try another tube?

Magic eye tubes get dimmer when they wear out,Is yours new?

Tried but nothing.
This is how it should be!

Check your grid circuit. These tubes run in Grid Leak Bias mode. If the grid to ground resistor is not large enough it may not work properly. You should have about -10V and possibly as much as -14V on the grid.

A very high input impedance volt meter is necessary to measure the grid voltage.
