    Don't change the output transformer tap you are currently using when you install your impedance selector. If you are using the 8 ohm tap for NFB leave it connected to the 8 ohm tap, not the switch output. You don't want the NFB level to change when you move your speaker impedance switch.

    PROBLEM:

    amp has been fine; many hours of use at volume, then this morning was playing it at volume (with FB switch in 'quietest/cleanest' position, if it matters) and it blew fuse/stopped playing

    pulled all the tubes, turn amp on, light bulb limiter full on= short


    can one of you fellas give me a quick troubleshoot on what/where to test first???
