How long should an Air Brake last? Resistors and such. I've had and used mine for a few years now. It's an older one with the Trainwreck logo. I have recently heard some crackling and popping noises and immediately shut down and removed it from my amp. Without it hooked up there is no noise. I'm afraid to try it again. Can it harm the amp if it is dying or in need of a fix?

There are screws and nuts holding the wipers in place on that big resistor - if something were to come loose you might have anything in particular happening there.

could be a dirty connection where the cables plug in, clean them and your cables ends too Todd

I realized I didn't really answer the question - it should last the life of your amp. Resistors don't wear out unless you burn them up. I don't think you'll ever burn up the resistors in the Airbrake unless you're running an amp over 100 watts into it and have it cranked down to the most attenuation. Or drop the Airbrake pretty hard - that might crack the ceramic base of the big resistors in there.
Under normal use it will last a long long time.

Did you notice a bowl of Rice Krispies nearby? Check for that.

I'll check and tighten everything.

The resister should last, but you can wear out a wiper on a varistor and get some non linearity in spots. Inspect it with good light and magnification.
