Speaker Trouble
A few weeks ago while installing replacement workstations, I came across a ‘pair’ of speakers that didn’t work properly. The ‘pair’ were in fact two completely different speakers that happened to have compatible interconnects. They needed a 15V power supply, but had a 9V one. The 9V power supply plug was held in with blue-tack because it didn’t fit properly.
Nobody had ever reported this problem.
I daresay if they needed a 9v supply, and someone blu-tacked in a 15v one then they might have been a tad speedier at letting you know there was a problem.
That’s assuming the extra 6v were enough to cause interesting side effects like a loud pop, or a melty-plasticy-smell (highly technical term, there).
I was working in field service and drove 30 miles to look at a none working keyboard, when I got there I found the ps2 connector was connected to – a screw hole in the monitor, the girl on the desk actually thought thats where it went. :)
