    Hi Tech guys, I am just a cabinet maker and want to remodel a old
    floor console TV cabinet for a new table model 27". My concern is the
    HV in the CRT, whether or not the bleeder resistor will drain the
    voltage from the cap or not, so when I remove the old workings from
    the cabinet.
    I know very little about this type of electronics. Also if I remember
    from 30+ years ago when I was in radar school for the military, that
    the only real sensitive part of the CRT is the yoke. I don't want to
    pull out the CRT and have it implode.

    Can anyone help.

    1) For transport handling, connect a wire first to the chassis, and then
    with a well insulated tool, connect the other end of that wire to the
    CRT at the high voltage cap.
    2) There is no bleeder resistor; high voltage can exist at the CRT for
    years, and even after the discharge previously mentioned.
    3) Stress on the neck can cause similar damage.
