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

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.

Peavey classic 50 reverb stopped working and now when you turn the reverb knob it makes the tone of the amp brighter and lots of buzz

I do not have one of these but It sounds like an open connection or broken wire. Check the peddle and associated wiring first and be sure it is OK, if possible swap with a known good one to be sure. If it is not the peddle wireing and associated jacks it is probably an open wire on the reverb pot.

Peavey 6505 plus buzz...even when all controls on zero and no guitar plugged in

Sounds like a bad power supply filter cap...the buzz you're hearing is the 60 cycles hum that filter caps reduce or (hopefully) eliminate altogether. It may also be related to the tubes but finding the bad one will require some work. Any friends have this same amp? If so, try swapping one tube at a time and see if you get lucky. If this amp is new take it back ASAP as it is a manufacturing defect.

Amp hum

Could be a couple things. Check grounds. Make sure cables do not have broken conductors, Make sure all tubes are fully seated. look for broken wires on chassis, spray a little contact cleaner into the jacks and insert and pull out plug a few times to clean the interrupts. Check the tubes for heater to cathode shorts,

Check for florescent lighting and similar noise sources with an AM/MW transistor radio, and if nothing is found externally, then you need to look at the condition of the filter caps in the power supply. The filter caps "may" show signs of failure, such as bulging, or leaking a black ooze, but they can also fail with no outward evidence.

This is on a 15 watt Peavey Vypyr. I have a buzzing at the bottom end of my amp, when playing on the low E string. I plugged in my headphones and the buzzing went away while playing. I have also raised my...

The voice coil on the cube speakers must be scraping against the magnet.Or the speaker cone must be damaged causing it to flutter at low frequency where there will be large cone movement. Try removing the phono jack from your musical instrument/ guitar and touch the tip of the jack with your finger. You will hear a hum, now turn down the volume and listen to the speakers very closely and see if you can identify the flutter. All the same you will have to fix the speaker or replace it. Have you ever dropped the speakers, if so the speaker frame could have warped causing the scraping noise.

Peavey classic chorus 212 buzzes, sguelches, squeals...

There MAY be a circuit trace on a board that is cracked OR a poor soldered connection. It is vibration sensitive as you have found. Changing a switch vibrates the unit.

Depending on what you have connected, this could even ba a bad input jack.

The unit needs to be serviced. You could open it and see if there is something obvious.
