Best Commercial White Wire Hack I've Seen

As an electronics tinkerer, I often take apart old electronics to salvage a nice audio pot here, a button there, etc... In my tinkering, I often come across white wire hacks, such as a wire after the fact soldered from one point to another, or something of the likes. Today I was taking apart a nice standard def analog Yamaha receiver that someone donated to my cause. I came across the most ridiculous white wire fix that I've seen in a commercial product to date. Did I mention that this is a nice expensive Yamaha product?

The Hack - Dead Bugs in a Yamaha RX-V890 Natural Sound Receiver

Unfortunately the receiver was already in pieces by the time I noticed the hack. Here is the hack:
Do you see it? Gosh, I wish I had a camera that took better macro pictures. Let's try another picture to see if you can see the hack. Click on the pictures to get a clearer view.

Do you see it now? There are 2 relays dead-bugged with hot glue onto two ICs, 'Pass the Pigs' style. Bus wire is soldered to the relay pins down to the IC pins (most visible in the last picture). Hot glue keeps the wires and parts in place. I think those three sideways caps (most visible in the first picture) are part of the hack as well.


As far as hacks go, this one is really well done. I'd hope so, because some poor soul probably had to fix thousands of these. I'd also hope that it was done well because this is an expensive piece of equipment. Regardless, it isn't what I was expecting to find taking apart this receiver. Who knows what other commercial products have crazy hacks!


  1. Might this not be a repair or after-market mod? Would be interesting to know the history of the unit and if any other units are like this...

  2. Good questions, I'll have to ask the original owners if they ever took it in for repair. I'm betting original setup from the factory. The wires match the board all too well.

  3. This will enable you gain the necessary experience in case you want to establish on your own. electricians in medford nj
