Review: Works great, it’s almost free! - I’m using this to drive an 8-inch guitar speaker in a small practice amp i made. It’s clean it’s quiet and can produce a good volume when turned up. I’m using a 20 volt dc ps. The only thing I’d caution you on is to be gentle with the volume pot. It seems a little fragile since it’s just mounted on the board. Otherwise this is a great little amp, and no soldering needed.
Review: Economical reuse of speakers/woofers! - The perfect device to reuse the gen 1 echo speakers and PSU! I use it as a mono speaker to reference my music production/have a speaker for my Yamaha DX7. Definitely reference the original pictures to make sure you get your psu polarity correct and double check your polarity on the input lines. Also seems like an economical way to get audio in your car if your head unit doesn't work and can tap the 12v DC line and ground.
