I wounder if anyone has a simple circuit for testing magic eyes.
i can test them on my taylor 45d but they dont glow.
what i envisage is box with say 4 valve holders one for each of the common eyes
this is to save on any complex switching.
i think it will need app 180 volt ht 6.3 volt for heaters and a varible 0 to -20 volts for the controle grid.
has any one built such a device?
