Question about Amplifiers & Preamps

Elevating loud noise and pop

Got this new about one year ago and recently it will start this hissing noise-floor type of sound through the speaker that eleveates in volume until it pops real loud (and then it's done). I unplugged the pedal switch and the speaker input, but it still does it. It happens randomly, and will repeat, making it unreliable for gigs. thanks for the help!

Hi melissa961

Not sure what make and model your rig is but the symptoms you have are classic for a failing transistor or capacitor. There is not a lot you can do about this except trace down the faulty part and replace it. We do this in the workshop by cyclic heating with a heat gun, and cooling of individual components with freeze spray until we locate the offending part. If it is a year old, I am hoping that it had a 1 year warranty, and that you are close enough to the end of it that you can claim the repairs as warranty. Sorry that this does not actually fix the problem for you, but now you know what you have to do next. Get the amp back to the retailer you purchased it from. Hope it all works out for you. If my advice has helped to resolve the problem for you, a FixYa rating from you would be great. Cheers

regards

Guitar amp continuous humming from speaker


Firstly, do not disconnect the speakers from the amp when it is on. Damage is possible.

You have a bad ground somewhere in the hookup. The first suspect would be your guitar-to-amp cord shielding connections at each plug, then, the wiring in your guitar. Try changing each of these to another as a trial, one at a time.

My teac MA-7 amplifier makes a very loud bang (rather a very loud clicking noise) a few seconds after I turn it on, and then every 5 minutes or so. Even with volume all the way down, even with no inputs...


All I can tell you is that if the noise is on both channels the cause of it has to be something that is both channels running to it or is something to do with the power supply. If the main amp channels are outputted by one device I would blame it on that. But if they are separate you will need to look elsewhere.

PyLE PT2000 Power Amplifier' { is it worth it??}


People talk alot of **** about Pyle amps, all I can say is that,
I have two PT-2000 & PT-1800 power amps that I have set in bridge mode, one for each speaker and they are powering two Altec-Lansing 18" inch subs, one amp per speaker, no hiss, line noise or anything and the system kicks. I tried the Pyles on a whim because I got tired the trouble I was having with the QSC and Crown power amps, could not go a year without having something go wrong always sending back to dealer for some kind of fix! So now I have 2, QSCs, 2 Crowns & 4 Pyles driving my system

Guitar amp make large crescendo-like noise, loud pop at end.


Same loudness, no speaker? This sounds (no pun intended) like a filter capacitor shorting out. Open it up and VERY CAUTIOUSLY look for what is making the noise. Filter capacitors can eject hot stuff. Very dangerous.

PEAVEY djs4 speaker QUESTION


If a speaker is "blown", there is normally an open-circuit in the voice coil, therefore it emits no sound at all. Can't discount a loose wire, but blown HF drivers are very common.
