Buzzing bass Amp combo

I have a tnt 115 bass amp combo from peavey. Its probably 7 or 8 years old. Lately when I turn it on there is a loud buzzing sound. When I turn up the volume it gets higher, when I turn down the volume it gets quieter but it still very loud and never goes away. I unplugged my bass and the sound is still there so it is definitely the amp. I feel like some of the components in the circuitry are bad. Please let me know if you know what could be making the sound. Thanks

Re: 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.

It's the battery, not enough juice to supply your amp at loud volumes so the bass will drop out especially on long bass notes. Replace your battery!

Amplifiers GT Series GT5-A604 ........explain settings

the amp probably has a x-over knob, a bass boost knob, and an eq knob. the eq is probably an internal crossover switch that will take the output from either high range (tweeters) or full range (6x9s) or low pass (subs) leave it on low pass. the bass boost however, will add distortion if turned up too high. its not noticable in the car, actually it sounds louder in the car but if you open the trunk and listen, you can tell its distorted bass and actually frying your speakers. the x-over knob is used to tune the frequency at which the amp stops pushing out bass tones. if you like rock music loud, turn it up higher, if you like low deep rap bass, turn it lower. keeping it too high might give you bad sound from either type though. ALSO THE GAIN OR LEVEL.IT IS NOT TO MAKE YOUR SUBS LOUDER IT WILL BLOW THEM .the gain is used to set your amp to your head unit which there is a procedure to do it.

Perfect ten bass amp, guitar

can you use headphones? if so do they sound normal. probably have bad filter caps. 2200uf caps big ones, go bad and lose their capacitance and cant process the low end notes, sounds like a motorboat or ******* out. speaker may have issues as well. get the caps from and careful of stored voltage on the capacitors it is deadly....... those caps are less than 2 bucks each.

A Buzzing noise from my Reverb section of the amplifier

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.

Ive bought a Peavey 1500 pa amplifier and would like to know are the a b knobs on the front treble and bass.If they are how would I take the outputs at the back of the amp to my Soundcraft mixer.

The Peavey A/B controls are output gain controls. Your mixers stereo output goes into the amps inputs, channels A & B. The Peavey is the output stage to your speaker system. If you you connect the outputs from a power amp to the inputs of a mixer you will blow the mixers input stage, amongst many other things and possibly damage the amplifier too. The bias (Bass, Mid, Treble controls) are on the mixer, not the amplifier. Unless you are using a mixer amp, which you are not. A PA system DOES NOT work in the same way as an intergrated hi fi amp.

Peavey Bass amp 115

HI Subicbay,

ADjust your Gain setting to limit just enough so the amp does not go into Protect mode. Turn your Gain all the way down, then crank up the bass from your system. GRadually turn up the gain until you trip on protect. Turn the gain back a notch and your set for no more protect.

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

Probably a loose coil or bad ground in the amp itself. Contact, 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.
