Fried chips

We had a power glitch the other day.   Not one of the more common sub-second extinguishing of the lights combined with the beep of the UPSs cutting in.    This time, UPSs went beep, but Anita's PC, mains powered, (no battery) but connected to the UPS) went down, but the lights stayed on,  the clocks kept the time, and everything else seemed normal.   Strange, a power spike maybe.

Until that is, I turned on the stereo.  Most of the time it was working fine, but a couple of times at first, and then all the time, it was emitting a nasty chug-chugging sound in all of the speakers.   Sounded like a power supply problem.  The process of elimination traced it to my hitherto faithful Behringer cross-over.

I use this device as a low-pass filter to drive the bass bins, and although it can be used as a three-way cross-over, the sound quality is not good enough for the mid-range or treble, but it is fine for the bass.  It has died.   Fortunately I have a less versatile but fully adequate substitute, and my stereo is back in fine fettle. I am unlikely to be able to fix the Behringer, so it's probably for the dump.
