here is an admiral 19A11 set that i have downstairs,perfect working chassis and perfect 7jp4,has a cracked cabinet and got tired of seeing it sit around.. so i removed the 7jp4 and installed a 7gp1 (green screen) and adapted one of my crt clocks,nice large numbers..i used a 5 volt regulated supply for the filament to make the 7gp1 will last awhile..different,as i like to be different.
this will go on top of my other 7" electrostaic sets..
