One of my Bose Soundtouch 10 speakers has died. It was working perfectly last week, but on attempting a kitchen concert last night, one of the pair was totally dead - no blinkenlights, no noise, no response to Bluetooth or Wifi, not visible on the apps of various devices. Used a different (and definitely working) wall-wart; no change. I suspect something in the power circuitry inside the box is poorly. As they're no longer made, and they are rather good (especially since the AirPlay update), the secondhand prices on Bay of Es are stupid, so I'd like to get it repaired if possible. Anyone know of someone in the South Suffolk/North Essex area who might attempt this with a reasonable chance of success?
