It's been years since I'd soldered anything but I managed to pull this one off after I'd figured out I'd put the transistor in the wrong way. It's not that difficult, really. I have powered studio monitors in my living room. They have an auto on/off feature but it's too sensitive. If you turn the music to background levels the speakers switched off.

The little T-Amp I use to power my bedroom speakers doesn't cause any audible static or hum.
