Luckily enough, I have a Micro Center (mostly a computer store, but has other things in it) sort of near to me, and I had to go to pick up some supplies on Saturday. Well, they didn’t have exactly what I wanted, so to use up the rest of my time there I looked in the hobby section. To my surprise, they had some Parts Express items there. Apart from an unopened pair of Overnight Sensation kits, some raw drivers, and some preamp bits, they had a couple of little amp boards. This one ( https://www.parts-express.com/Stereo-4.2-Bluetooth-2-x-30W-Amp-Board-with-Volume-Control-USB-Reader-Charger-and-IR-Remot-320-641 ) was there for a dollar less than on site. No, I didn’t buy it, but I could have.
Just goes to show you never know where you’ll see a familiar name / thing.
