Some older types of computer monitors have the focus bleeder, also some other TV's from the late 70's/early 80's. A lot of the time there is two wires going into the anode connector....one is the HV out from the rectifier and the other is the HV in to the focus divider.
I'll look tonight and see if I have any junk sets/monitors with the focus divider.
The later RCA tube type portables (later model ctc-52, also ctc-66? etc.) use a high voltage focus CRT and use an HV tripler off the flyback rather than the 3A3 rectifier and low focus voltage crt.
