A Buzzing noise from my Reverb section of the amplifier

Hi there

When I play my keyboard on my Peavey Combo, if I turn on the Reverb I get a buzzing. Is this to do with grounding or noise reduction that maybe a capacitor has failed?..Or is there a general circuit that controls this that has failed and needs replacing?

Is it easily repaired and a basic costing would be??

Many thx

Phil

I am sensing 60 cycle hum. the reverb will draw more power. i would try what is actually powering the units. power strip??? off of an unknown amperage power outlet? if the electrical system that feeds the a/c outlet is ran in series, you may not be getting enough juice or the outlets have bad grounds. i dont see a capacitor causing the buzz noise, but more of a pop and then sudden loss of signal. may be a resistor. also if you have a reverb tank the lines maybe mixed up in/out, or the tank is going bad.

My powered mixer Behringer is buzzing


Make sure the buzz doesn't happen because of feedback of speakers into mics. When feedback is processed it often goes to a buzz instead of the usual howl.

Also check that you are running adequate inout into the effect since a very low inout will incur digitizing noise and loss of signal=to-noise ratio.

To get rid of the buzzing sound just go to walmart and in the car stereo section buy the $10 rca ground loop isolator, this is the best way to get rid of amp noise

Noisy/buzz


Usally a ground loop isolator will fix that problem. It plugs into the RCA's between the radio and the amp.

Try to reground the amp in a different spot.

Or run a refrence ground from the deck to the amp next to the remote turn on wire. (still keep your main amp ground hooked up)

DO NOT run your power wire next to the RCA's, that will induce a field which in turn can cause that buzzing sound.

My paeveybandit 112 is buzing when i turn it up


Check the power supply area for bad connections especially near the large capacitors. If one or more of those are disconnected, the DC voltage will have some noisy AC on it that will sound like a buzz.

Keep us posted.

Peavey bandit guitar amplifier problem


Hello gotemneedem,

I would try using an electronic cleaner on the pot(s) to see if that helps. Many times either the surface of the coil, the wiper, or both become contaminated with excessive residue and fail as you describe. Shaking it or moving it quickly sometimes removes enough of the contamination for it to temporarily function again. But if you clean all of the gunk off, it will work like new. Try this inexpensive Radio Shack product. If it doesn't fix the problem, you'll need to replace the pot.

Hope this helps. If it does, please rate as "FixYa".

Volume goes up and down on its own + a lot of scrachy noises when


You have dirty potentiometer (pot) controls. Unfortunately to clean them properly you will have to remove the amplifier from the wooden cabinet. If you're not comfortable doing this then send it to a local musical instrument/amp repair shop.

1) Disconnect AC power (duh)
2) After carefully documenting all connections, unplug/disconnect speaker, footswitch and the reverb wires on the back of the amplifier.
3) Look for four screws along top of wood cabinet that hold the inverted amplifier in place (thank you Leo Fender). Normally there is a wood block that will prevent the amplifier chassis from dropping down as the four screws are removed BUT assume nothing.
4) When amplifier is completely free from the cabinet top, carefully slide it out the backside.
5) Up on the bench avoid the filter capacitors (look like a C size battery) in the amplifier chassis located over by the AC power cord as they may still hold an electrical charge.
6) Look for the three terminals exiting each pot along the front of the amplifier chassis. Using a PLASTIC SAFE tuner/control cleaner/lube (Radio Shack Model 64-4315/Catalog #64-4315) aim the extension nozzle into the open area where the three terminals enter the pot.
7) Turn the pot knob CW/CCW while dispensing a small amount of.the control cleaner. Repeat with all controls.
8) Re-assemble (don't forget to reconnect all the wiring from step #2) and download a couple of new guitar TAB's for proper testing inspiration.....Glen :-)

Buzzing bass Amp combo


The problem you have mentioned is a common one with old sets, but it also occurs in new ones also, though not frequent. You can fix this just by changing the electrolytic filter capacitors in the power supply and sub filters on the amp PCB. The new capacitors should be of the same or higher voltage rating and same capacity rating as of the existing ones. And as it is such an old one, it is better to change all the electrolytic capacitors to avoid any further problems.

Guitar Amp trouble...... Gets power but either no sound or very little.


Your problem sounds very similar to mine. I have a Marshal that does the same thing. It gets power but either no sound comes out or it's fragmented and buzzing. I took the circuit board out and found that a fuse had pulled/been knocked loose and was hanging free. If you take your amp apart, make sure you unplug it first. You're going to be be looking for something that look likes a small lego that suspended above the circuit board by wires coming out of both ends. If ones of these wires has pulled free then that's your problem. You can temporarily fix it by pressing the wire back into the circuit board and placing electrical tape over the top of the fuse to hold it all in place. If you do this, however, you can't play loud or it will rattle loose again and you don't really get more than about 10 minutes of play time. I'm about to solder mine whenever the guns arrives, so I'll let you know if this is a DIY project or not.

When amp powers up it makes a buzzing noise-quite loud-


Probably a loose coil or bad ground in the amp itself. Contact www.audiotekx.com, ask for Jason, he can help you and is the best out there. The problem you're having is extremely tricky to rectify, I had an amp with the same problem at it stumped multiple techs, some that had been in the business 35 years, yet Jason got it solved.
