    Hi,
    I have a QSC PL 4.0 audio amplifier. It's 120v version. I need it run at 230v, and have the schematics of this. I have attached it to this post.
    According to the Ac Filter sheet, I disconnect W1 and W2, connect W3. Is this right?
    Please let me know,
    Thank you!

    How about saving me 15 minutes and telling me which page you're talking about?
    That schematic is so hard to read!

    Page 6, B2? T801?

    and where is the other end of J812, pins 3 and 4?

    Repeating myself: Starting from page 6, area B2, T801...Where is the other end of J812, pins 3 and 4?
    and Page 6 area C4, where is the other end of J811?
