SWR - Speaker Blown?

    I recently bought a used SWR Super Redhead and I love the tones I can get from it. Recently I've heard a buzzing coming from one of the 10" speakers when I hit any sustained low notes.

    I've never needed to have a speaker reconed but honestly I'm not sure it's blown as it happens intermittently.

    Does anyone have some advise on this?

    The intermittent buzzing could be something as simple as one of the speaker wires from the amp to the speaker laying against the back of the basket buzzing on some notes, the spider getting ready to give up or just an all-out failed speaker.

    Whatever it is you can have them reconed. I had one done last year and I think it cost me about $50. Just call SWR/Fender. They'll tell you where to send it.

    I have a cracking and popping sound on my SWR LA 15 100 watt practice amp, I thought it was a blown speaker, so I ordered a replacement and installed. still getting the same sound. Can anyone help diagnose this problem for me. All my main gear have been SWR for the last 10 years, I just played on a Hartke 15 kickback 500 watt unit , which I think I will buy, but I would like to fix this amp in the meantime ! any help would be appreciated !
     
  5. Ray, if the amp has an effects loop try linking the send and return with a signal cable and see if that helps.

    Things I'd check that aren't the amp:
    Instrument cable, preamp battery (if your bass has one)
    Things I'd check that are the amp:
    Effects loop corrosion (try connecting the send and return with an instrument cable and see if the cracking goes away)
    I put jack corrosion (try plugging your bass directly into the effects return)
    Faulty tube (if applicable)
    If none of those work, it's probably the transistor bias, PS caps, or something else. Either way, it's tech time.
     
  7. Does the headphone jack interrupt the the speaker? If it does you may try using that first to see if the trouble is present in phones and if not exercising that jack several times.
