Peavey amp makes loud "pop" sound when turned on

Jacek Jakubek · Post by **Jacek Jakubek** » 11 Mar 2020 10:34 am

I recently got a Peavey amp (Nashville 400) and when I turn it on, it makes a sort of loud "pop" sound. Otherwise the amp works OK and doesn't make this sound when I turn it off, just when turning on. My other Peavey
amps don't do this.

Anyone know why this happens and if it is a sign of a problem with the circuitry?

I have taken out the chassis to spray some deoxit in the pots, so if there is an easy fix for the "pop" I'm willing to try it.

Try unplugging the reverb pan and try turning it on and see if that helps.

Many of the Peavey amps I own have done this since new. If you search the forum, it has been covered before and deemed normal. Turn your master volume all way down before shutting off helps some.

Perfectly normal.

The bigger question is: does anybody have a Nashville 400 that doesn't pop when you turn it on?

Mine is 'normal' in that it pops when you turn it on and it has continual reverb problems with the molex connector. A great amp with two known quirks...

I had this problem with a NV 1000. Some players told me you could destroy you speaker with it. I took mine and had it repaired. Do not remember what they did,or where I took it.

That's pure bunk, they told you wrong. $:\$

The pulse (pop, snap, crack, or whatever you want to call it) is far too low in amplitude and too short in duration to cause speaker damage.

But it can be irritating.

This is a common (and non destructive) trait in many older Peavey amps. It does no harm to the equipment. Its not just the Peavey steel guitar amps. I had a Peavey, mid 90's TNT 115S, bass amp that did the same thing. Peavey fixed it in later amps such as the Nashville 112.

The issue is the power supply DC voltages come on immediately when powered on and the initial voltage surge causes the pop.

I have a NV112 that does this too. I even sent it back to Peavey to fix it and it still does it. You can plug a cord into the headphone jack and turn it on. Then you won't hear a thing. Unplug the jack and carry on.

Thanks for posting your question. Mine started making a real loud pop that caused the speaker to move a lot when I turned OFF the amp. I sent in the chassis to Peavey and they corrected the problem along with getting the reverb to work again. I was told that they touched up a few solder joints. This was last Summer. Now the reverb quit again and it is making the less offensive pop when I turn it ON. Now with all of the replies,I'm seeing that it's a common thing.

Don't worry-they all do it!

Yes, and the cause is simply a poor design.

Any kind of switch-on thump on any amp (guitar or hi-fi) is unacceptable.

As Donny says, it's poor design - a polite expression for cheap laziness.

DC can and should be applied in a timely manner.

my old pv does the opposite.. loud as hell pop when turned off, quiet when started up... bob

I've also had this problem with Peavey amps. I just turned the volume off before turning it on. Pretty common thing that is not harmful to your amp.

Were you standing in front of the amp, or behind it?

Donny Hinson · Post by **Donny Hinson** » 6 Jun 2020 5:35 am

Georg, how about using hybrid caps in the power supply? That might be a good place to start!

The Nashville pop
Sometimes mine is perfectly quite coming on....other times it's BOOM! I never know when it will do it.
I get a kick out of the looks I get on the bandstand...lol
