Hi chillin884

Not a good sign. Something has gone wrong with the output stages of your Peavey. It is not a good idea to continue plugging it in as damage may occur to your speakers. I suggest you take it to a decent music gear repair guy for a look see and give you a quote to repair These heads, like all Peavey gear, are pretty solid and worth repair. Sorry to be the bearer of bad news like this, good luck

SOURCE: peavey banit 65 guitar amp. When

A few things can cause it. Bad ground\bad power supply filter capacitor\bad low level op amp IC. You most likely have a bad power supply or trouble at your input jack. Good luck!

Call the Peavey Customer Service line (number available @ the Peavey site) and get the parts department to email you a schematics on the amp... it has the footswitch wiring on it. And it's free to do this.

I have a Sony STR-DE135 receiver emitting a persistent hissing sound on all functions and inputs (CD, Tuner, TV/Sat, MD/Tape, Video). I have a pair of Boston Acoustic CR5 speakers attached. Any ideas on...


most hissing problems come from earth issues within the system them selves, i dont recommend taking the case of and plugin it in to start testing if its an earth problem. So my best solution is to simply take it your local music or electrical shop and pay for a repair or see id they can diagnose the issue, other than that i dont have a solution for you. I have a little guitar amp which was buzzing it's little heart out, but when i touched my guitar strings the buzzing stops (as i become the earth on touching it) so i tried my guitar on a different amp and it was fine, so my little amp was the problem, i took it apart and noticed that the screw for the earth was loose, once i tightened it the problem stopped and all is good. best regards.

My amp wont turn on


I have heard this problem occurs often with the vypyr I have heard to try and turn it oun without your guitar cable plugged in and it should work fine. If not try wiggling the guitar cable out a little and and should turn on and try and get the update for it.

MY FENDER GUITAR AMPLIFIER IS MAKING A HUMMING BUZZING NOISE


Not sure yet, but before considering a fault with the amp, does it only make this humming noise when not plugged into the guitar? I am thinking that the cable might be faulty.

If it while the cable is plugged in the guitar, does the humming disappear when you turn the volume control(s) down on the guitar? I am thinking that one or pickups may be faulty.

I just bought some pioneer ts-w305c subs from some guy in canada and one of them is sounds distorted< when barely playin it buzzes can u help me?


This could be either the speaker that is blown and making the noise or part of the amplifier being smoked causing distortion that sounds like a blown speaker. WIthout taking it apart and looking at waveforms on an oscilloscope, I can't tell you which is the problem. I'd ask a local shop to test it for you or if you can, exchange the actual speakers between the two. IF the problem stays with the bad box, the problem is with the amp, if the good speaker works OK in the "bad box" then the speaker is blown.

Keep us posted.

Hi i use a peavey 6505 Amp head and when i run a seymour duncan pickup booster through the effects loop it blows the amp (possibly the pre-amp fuses) i want to get a volume boost in a distorted setting...


Hi bmwz43

Odd that you keep blowing the head... and with 5 12axl preamp tubes even more surprised that you cannot get enough gain... :) Get the correct pedal for the 6505 and change yo levels that way. Hard to beat classic tube amp for tone:)

Check the the amp has the correct impedance setting for the quaddy you are using.

One more thing, what sort of cable do you have connecting the amp to the speaker box. If you use a cheapo guitar jumper lead arrangement, expect that to give you trouble AND **** tone. The 6505 has 120watts of cranked up tube output. Tube output stages need a solid at least 18 gauge cable and quality connector jacks, like Switchcraft. They can blow fuses if you don't use a decent speaker connector lead.

Get back to me here if it does it again, and check to see exactly which fuse you are replacing. It can help sort out the problem.

A HUMMING Peavey Classic 30


I repaired a classic 50 recently and the problem was a bad solder connection on the main input jack. You may also want to have the tubes tested.

If the unit is over 20+ years have it recapped.

I do this stuff but Vermont might be to far.

Buzzing emitted by vsx-409


Could be the result of having DTS compatible equipment connected through the analog inputs on the VSX-409D. Noise and distortion will result as essentially the DTS signal is being played back undecoded. If this is the case you'll have to connect your LD or CD player through the digital connections (coax or optical) and set 'Signal Select' (button on front) to 'Digital'.

Distortion/noise and buzz in front left speaker


Try to see if the reciever will make the buzzing/noise without anything connected to it except power, and speakers. Tune into a local radio station and see if the noise continues. If the noise has stopped, then you know there is an issue with the player or cable.
