Just how well/long do the brighteners work/last?
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?
