I've used Felix' circuit diagram to build switch inside an extension cord that powers the active speakers in my living room. My electronics skills are fairly limited, but I got it to work after first mounting the transistor the wrong way around. Note that ampswitch doesn't work if you're using Squeezenetwork. > I'm interested to hear how you have solved the voltage to Felix > AmpSwitch together with the t-amp. > > I myself have bought a pair of t-amps and have hooked one up to a > sealed motorcycle battery that I had lying around.

But mine are plugged into an AC adapter and they use so little power that I decided to keep them on permanently. They're quiet enough for that, I only hear a little noise if I put my ear against the speakers. I asked Felix if changing the relay to a 12 volt version would be enough, and he suggested changing the resistors to 3.3k ohm as well (no guarantees, of course, if you break anything, you get to keep the pieces). I think the t-amp housing is big enough to put the circuit inside the battery compartment. I intenden to add a manual override switch and a mini-jack connector to the housing. That way the only thing needed to use ampswitch would be a jack - jack cord running to the SB headphone connector. Quite an elegant solution for an SB T-Amp combo...
