Today I got four Aviom mixers (cheap at eBay) for my studio monitoring. The guy that packed them did everything top notch except he packed them two and two wrapped in bubble wrap with nothing in between the units. Duhhhh!!.. So one of the units had a few buttons hit badly so they got scratched and a few that had fallen off. One got hit so badly that the small switch inside (on the PCB) was split, with two tiny parts laying among the buttons in the bubble wrap. Luckily the sound of loose parts warned me so I found all loose parts, found out what was wrong, opened the unit, googled a little and then managed to repair that small switch with some two component glue. Really grateful for the DIY education lately! Totally different attitude when opening units and troubleshooting these days.

My first repair was a CD player. I traded a guy some skateboard parts for it when i was about 13 or 14. It's a first gen carousel type and I still use it! My grandfather dealt in military surplus electronics, so I was always around it. I was always fascinated with the thought that all those little parts on the boards made stuff happen.
Anyway, I got the player and took it apart. I noticed that a couple of the little parts with colored bands (resistors) looked burned. I also noticed that a lot of the other parts around those had exactly the same colors, so I figured these must also be like those. I dug through piles of electronics to find a couple resistors with those same bands. I then stole my dad's soldering iron and went to town.
Somehow I got those resistors onto the board without tearing anything up and the player worked from that point on.
I still don't even know if they were the right values for those spots.
That's the story of my first DIY and first repair. I've been hooked ever since.

Oh yes,
as a young bassman, i always wondered how our tech could repair all that different gear. I had no clue what he was talking about when he explained what he does most of the time. Once he phoned me about if i would like the limiter of my faulty bass amp working different and kicking in more early, that amp had a transistor blown up...i was mighty impressed....
I wanted to be able to do such stuff. Now, after many years of past diy i can be this tech myself, and that is a really good feeling...
Synth output stage distorts? Well, let's have a look...
Knob broken or scratchy? Wait, i order a replacement part, no prob.
Left channel cracks from time to time? Ah, i see, there's a capacitor gone leaky, i will replace them on both channels...btw, i replace them with two bigger ones. Sounds better now, you see?
Great feeling, once you get this type of understanding, and it does not even effort too much of practice and reading to get to this point.
Never thought i would be capable of doing such kind of stuff as a young man ...
