It's 10am on a stiflingly hot Monday morning, and a Soundcraft mixer is giving Adrian Nettleship a headache. The sound is only coming out of one channel – the friend who it belongs to thought the XLR port was at fault, but that's working fine, so Adrian and his fellow repairers have connected an oscilloscope to it to follow the signal and attempt to pinpoint the problem. But so far, no joy. "I need a KitKat," Adrian says.
He's part of the Forest Fixers, a group of volunteers who run regular repair cafes throughout the London borough of Waltham Forest. Usually, they’re open to walk-ins – they get a lot of kitchen appliances like toasters and coffee machines – but today it's a closed shop. That's because today is audio day.
