    Can it wreck an amp to turn on a solid state amp with no speakers hooked up to it?
    Curiousity is an odd thing.

    thanks guys

    No problem with SS power amps, tube amps are a different story (or so I'm told). Happy New Year!

    most ss amps do fine into no load/infinity ohms
    i'd double check with the manufacturer anyhow.
    tube amps - a big no no

    It's fine so long as there is no output transformer, that means 99.9% of solidstate amps from the last 20-30 years.

    BUT... you should not plug in a speaker while the amp is on.

    You risk a momentary short while the plug goes in, especially with a 1/4" cable.
    Some amps might be damaged by that. Acoustic Image amps come with a big
    warning printed on the amp to never never do that.
  6. Yep, SS doesn't mind talkin to nothing..
    But Tubes...they get offended! :bassist:
