You can use a transformer or a brightener with a resistor run it at 7 volts or so and you will be happy and ßo will the crt, I've done it

As mentioned, my 24AHP4 is a bit weak, slow to come up to brightness, but after a few min, gives a pretty good picture, obviously on it's last legs, who knows how long.

The data page clearly states that the heater can run off of AC or DC current, so I was thinking of getting a 7 volt 2 amp dc regulated power supply, and giving the CRT tiny boost, 0.7 volts is not very much, but it will help a tiny bit, and that's all I really need. Right?
