Broken SWR WM 12

Discussion in 'Amps and Cabs [BG]' started by guitaron, Aug 28, 2002.

  1. I have a SWR workingman 12 that keeps on blowing
    fuses.I changed 2 already and now it is making a loud
    hum and does not work.
    Any idea of the problem!

    A fuse blowing is a symptom of a potential problem elsewhere. Take it to your nearest dealer if under warranty or a good local repairer if not.
  3. Even if it's not under warranty, you should still check out SWR's website and have an authorized servicer look at it. My WM10 had a problem and I had to do just that. I am not sorry now, since it works fine. This is probably the only drawback to the entire WM series; it is built to a pricepoint, as opposed to being built like a tank, like their professional series.
  4. One thing I was doing was to chain 2 amps.
    I used the SEND from an other amp and I pluged it
    in the in of the WM12. Was this a wrong thing to do?
    It seems to work well!
    Also is it bad to run an amp without the speaker pluged in?
  5. Oh! we've got funny business going on here.

    Lemme see.

    "Chaining" amps and WM 12 keeps blowing.
    That outta tell you something.

    I can run my SWR Pro Series amp w/o speakers, no problem. Can't speak for other types.
  6. I'd wager that the "chaining" was indeed the culprit, especially if you had it going into the "passive" input on the WM. A "Y" cord or BOSS multiple jack (J44) should be the way to go on that...or use the stereo feature on any FX that you may be using.
  7. Thanks for the replys guys.
    Does it means that the transformer would be burned
    since 2 fuses has burned also?
    I did take it to a repair center but it will take a long
    time to fix they told me....

    is a wm 12 loud enough to play with a drum and guitarist?
