I miss the days of buying electrical components at Radio Shack. I never had much luck with their through hole PCBs, they tended to produce cold solder joints (could have been my technique or the iron, though), but it certainly was convenient being able to buy electrical components the same day you needed them.They had OP amps, lots of stuff. I'm not sure what you are saying. Though over the years less and less. LOL
Plus, their kits were pretty useful. The last time I bought components at Radio Shack was probably around late 2015. I rigged up a wooden chest with a light, switch, speaker, amplifier, and an Arduino with PCM support to play the chest opening sound from The Legend of Zelda as a Christmas gift to one of my brothers. The amplifier was a Radio Shack kit with surface mount components, and that produced solid solder joints. The Arduino board was something I had to order online, so was the door switch I used as a trigger, but everything else came from Radio Shack. These days, I have to order electrical components online, there are no stores I’m aware of in my area that sells them. Heck, anything electronic that’s not a fairly mainstream consumer electronics product, I have to order online.
