    I also found this where down the bottom one person says where my Alltair is known for damaging Marshalls. Does anyone have any info about this occurring or not? Thanks

    And a little something I found while researching the Weber Mass 150

    Attenuators

    Thought for sure maybe Barry or Tony or some others might have had some insight about attenuators by now.

    I've been using Altair PW-5's for years.
    They work great, sound great and have never caused any damage to my amps.
    Keep in mind, they're intended for tube amps only.
    The blue ones have an XLR connector on the LINE OUTPUT.
    If I'm playing through a tube amp, there's an Altair in-line with it !

    I have a resistive attenuator that is a bit like the Altair or Power Soak. It is home-built, but it is basically a resistor voltage divider to dissipate heat and drop the voltage to the loudspeaker. It has a switchable "L-pad" after the big resistors to control the attenuation more precisely.

    I also have a Weber mini-mass, which uses a loudspeaker driver in the attenuator circuit, presumably adding some inductance. It is cute to see the voice coil of a loudspeaker wired into the circuit. It also includes some adjustable power resistors.

    What I found is that different amps work better with different attenuators. My Orange tiny terror (push-pull class AB) works best with the resistive attenuator. It sounds a bit artificial with the Weber mini-mass. On the other hand, my clean amp (a converted public address amp, class A, revoiced for guitar) sounds better with the mini-mass. I don't know why.

    I have Rivera RockCrusher, but I don't use it much since I sold the amp I bought it for.. But very good device if you have a non-master volume amp.

    I bought an Altair when they first came out - in the late 70's I think. I sold it a few years back because I wasn't using it. Recently I found I need to do something about my volume at home so I now use a Weber MiniMASS. IMO Weber makes excellent attenuators without breaking the bank.

    Thanks for that info, pete12string
