    PL700 Rebuild

    And tht board has the bias trannie ON THE BOARD , not on the chassis backwall.. You need a coupl 2N5088's stuffed in a P strap and bolted to the chassis..

    PL700 Rebuild

    Past build threads are a treasure trove of information. And if you go back far enough, ypu can see the evolution of White Oak and one man's idea of customer service and building the best product he can ....and then making it better.....and better....and better...

    phase linear 400

    Gene, when I blow up.400's like that, it's usually toomuch throttle. The detection IC is a new one. Haven't seen that one before..

    phase linear 400

    .5's will do to test...emitter resistor values were out of circuiut?

    PL7000S2

    Second that. I think seeing the progress on a day to day basis we don't appreciate the effort and tenacity associated with this project. George, I'm fuckin impressed. The amount of research done on your own is a testament to your commitment....excellent example of how to eat an elephant...

    phase linear 400

    Pico fuses are green, resistors looking types. Do your backplanes have glass fuses? Lie= low value resistors..

    phase linear 400

    Check emitter resistors on the backplanes, pico fuses and liw ohm resistors on backplane. Check bias trannies too.....it's not uncommon to have collateral damage after output shorts .. A lot less than before White Oak.
