    Bassman LTD rectifier swap

    I swapped out the GZ34 for a 5u4..seems to have tamed it a bit...and warmed it up..has anyone tried this?...it shouldnt hurt the amp right?...Fender suggest this in the manual...i like the tone much better...and i checked the tranformer...it was in the high 4s...so i am assuming its safe...any feedback would be appreciated...

    Pretty vague post, don't really know what you're asking.

    Manual

    It's safe if your power transformer can deliver the additional 1 amp of current that the tube takes to run.

    Rectumfriers

    Some amps can't deliver the additional current that some rectumfriers require.
    The super cool thing about my Double Deluxe is that I can vary the timbre,power,tonality,& headroom by swapping out the rectumfriers.
    It will run with 5y3,5v4,5u4,5r4,5ar4.

    You like the sound of yours because the voltage dropped when you plugged in that rectumfrier.
    That's ONE reason why real tweeds sound so cool.They run at lower voltage/higher current which gets rid of the icepic sound that a lot of modern amps have.

    On your amp you are supposed to rebias the power tubes when changing to a different rectumfrier.

    Here's the Double Deluxe.
    It runs on the above mentioned rectumfriers.
    That's a coke bottle 5r4 from the '50's and 6v6 tubes from the '60's,12ay7 & 12ax7 from the '60's,Weber Blue Dog & Silver Bell and load dump.

    Not a total waste of time. I for one liked peeking into the back of your amp.
    I bought a relic'd guitar because I liked the way it sounded. Then I refinished it because I didn't like the way it looked.

    Is the Weber Load Dump fastened to the magnet of the Silver Bell, or does it just appear to because of the angle?

    And I'm assuming that the Load Dump is either something like a Power Soak, or a resistor/impedance circuit to change the impedance load on the amp?

    (Yes, I could Google this, but I would rather get your take on it, as well as your opinion of how well it works.)

    The magnet holds the Load Dump.
    A Load Dump is an L-Pad. L pad - Wikipedia, the free encyclopedia
    VERY handy to have.

    You missed replying in 2013--which would have been cool
    Still some good info for anybody else...
    I've been a pilgrim on this earth, since the day of my birth, I'm a long way from my home.
