It could or could not hurt your amp depending on what it is, it could be dirty connections which can be cleaned with a good electrical contact cleaner, if that doesnt fix the problem then more than likely you have a resistor/resistors and or capacitor/capacitors going out or leaking if this is the case depending on which ones they are you will have serious amplifier problems at some point. Its well worth the cost to have a amp tech check out the amplifier, no need to fubar trannys on a hope of its nothing serious. Bob Feat Lil Wayne Strange Clouds. I wouldn't waste the money taking it to tech. Every solid state amp I have ever owned has popped at shut down at one time or another, and I have never had a major problem with any of them.

You could take an amp that functions perfectly to a tech, and they are likely to come up with reason to charge you for something. They are often just as bad as car mechanics. The golden rule is that if it isn't broken then don't fix it. Here are some explanations about why amps are known to pop during shut down from a solid state amp forum: weatherlght SSGuitar Apprentice One of my professors told me that its due to power suplly caps charge/discharge transients and that might just be the reason why valve amps dont have that pop. Valve amps have a series resistor / choke in their power supllies since valve amps draw small currents (500-1000mA). Problem is, with a solidstate amp (it draws like 2amps+) any significant resistance that I'll be puting in series to charge the caps slower will reduce some serious volts I'll need to ask around and come up with a solution. Enzo Legendary There are pops and there are thumps.

Pops are often from the power switch arcing as it opens. The fully charged amp circuits have enough energy stored to amplify that noise for the brief moment before they go silent.

That has nothing to do with filter cap discharge rates. Thumps, or that whump sound you sometimes get turning off is the result of everything collapsing. As power rails collapse, the amp goes through a moment of instability. Tube amps don;t pop at turn on, but they sure as hell pop at turn off.

One thing about the thump on a solid state amp. The highest voltage the amp has to deliver is one of its power rails. At turn off, those start to drop.

Whatever transient noise that results can be no larger than the loudest peak the amp could make during normal operation. If your speakers can handle the full power of the amp, then the turn off thump will be fine as well. To your speaker, it might as well be just another kick drum hit.
