Hi guys

I bought an Amp 6B two months ago and tested it when it arrived. It worked perfectly fine so I put it back in the ESD covering in the small cardboard box to let it wait while I finished other stuff so I could use the Amp 6B instead of the T2020 chinese knock-off eBay amp I have previously used in my Boominator.

When I connected the Amp 6 today and powered it up, absolutely NOTHING happened.

I have a multimeter and I measured the voltage going to the Amp 6 at 13 volts, and I made sure that the polarity was + on the inner side of the plug. The fuse is not broken and I am sure that my input device (HTC Desire) is working perfectly fine.

Am I correct when I have both jumpers shorted out when I want to play music?

Can you help me troubleshoot my Amp 6?
