  • d/c CRT power supply, technical

    hello,

    while testing my prospective car moniter, a 15" crt tube....

    i noticed the voltage out of the diode bridge on the internal ac-dc converter seemed like 2 +50 volt sources, not 1 +50 and one ground or -50volts. i know 50volts is what a 'bumpy' recitfied 120 volts looks like on a vom. if i wanted to 'substitue' that for a 50volt dc source, that would be two postive leads and then i would not know where to put the ground. any insight?

    i think that if i was able to figure this out; the moniter would draw around 5-12amps instead of the 20-25amps if i used an external dc/ac inverter. though part of the circuitry apears to use ac, i would need a small inverter to satisfy that.

    has anyone modifed a crt before in this way or know anything about it?

    thanks
    Corey
