    hey everyone

    i just bought a new 100 watt combo with 15inch speaker (it was a no name brand off ebay because i was on a budget). When i turn it on it has that crackly buzzing sound but after about 5 minutes it basically goes away.
    its actually a really great amp for the money but yeh im just wondering with the buzzing if it goes away after 5 minutes does that mean the amp just needs to warm up or something? Does anybody else have an experience similar to this?

    thanks heaps in advance
     
  2. Tube or Solid State? if it works well let it warm up then play but, 5 minutes does seem a bit much to warm up.

    Hi beni_25.

    Your amp's noise may be caused by a poor solder connection in its circuitry. After your rig has warmed up, heat causes the solder joint to expand and improve the connection.

    I'm not a tech though, so I'm only guessing.

    Which amp do you own? Do you have its manual?

    Details are helpful when seeking assistance in troubleshooting gear problems.

  7. Hi.

    Oh, boy what a brand name ;).

    I'd blame the loose/cold solder joints for the crackling also.

    Some of the cheaper end capacitors are also quite noisy when charging, but that shouldn't last more than a couple of seconds.

    Did the combo come with any kind of warranty?

    Regards

    just the typical 30 day money back that companies like that offer hehe.
    the sound isnt a problem really i am fine with it taking a minute to warm up i was just worried if was a long term technical problem
     
  9. Hi.

    That sucks.

    The good thing is that You like the tone, the bad thing is that the problem won't go away, but possibly get worse as a result of the vibration.

    I'd get that PCB looked at ASAP.

    Regards
    Sam
