Day 771 Wot no noise!

18th September 2019

Eight years ago, when my studio was still operational one of my monitor speakers developed a fault. There was a problem with the power supply that couldn’t be easily fixed without sending it back to the manufacturer.

Needless to say I didn’t do that. Instead I bought a new pair and consigned the old ones to the storage cupboard.

Fast forward to today, my friend Dave was coming over so I suggested we take a look at the faulty monitor. If anyone can figure out how to fix it, he could. I had marked the duff unit with red insulation tape, so the first step was to remove the back panel. We checked the circuit board for signs of heat damage, and found nothing. I powered up the unit, there was no load buzzing noise, so I fed an audio signal through it.

The music came through without any crackle, buzzing or distortion. I could not believe it, had it cured itself?

I left it on test for the rest of the day without any sign of the fault returning. I just can’t get over it.
