    Yeah that idea had already dawned on me. I'll have to check that out in the afternoon. Would the Infinium version have the same fuses as the non-Infinium, because that schematic piece of the power...

    The fuse that was in it when I got it from a friend was a 2A. He was getting the no sound and check tube LEDs. Obviously he must've changed the F4 fuse with an incorrect replacement. I don't know...

    I was in contact awhile back with Bugera tech support about the fuses. "Thanks for contacting us!
    Fuse F1-F4 are all 2 amp slow blow fuses. "

    New EL34s with same result with blowing the fuse when multiple tubes are in. I also see nothing awkward like a screw shorting out a socket. I guess I'll just reflow all the points on the output...

    I in fact do have 6V across the pins and sockets. My fuse wasn't making solid contact to the terminals as they were a little wonky. I had all the tubes on the output board pulled with 6V to the...

    The voltages I tested on the EL34 sockets were with the tubes pulled. I also did pull the fuse to test it and it was fine after running for a bit with no tubes in the output board.
