Reset transformer on Event 20/20 bas active speakers

Thought I’d just put this up for my own record and because I didn’t find anything online that gave anything useful. Here’s how to change the input voltage on these Event active speakers from 110V to 240V. Photos should be self explanatory. Ignore the warning about no serviceable parts but heed the one about electrical shock – those capacitors are big and could carry quite a charge, even after unplugging, try not to touch the circuit board unless you’re sure you’ve discharged everything.

Why have I got them? I’m looking after them for my neighbour, Matthew Barney collaborator Jonathan Bepler. Once playing, they’re good but they’re noisy buggers when there’s no input – think this is what drove him mad in his studio.
