Hi, I read through the thread and built a pair of headphones, i got a SRM 007t to use with them but i would like to rewire it for 220V. As you can see i have reconnected the purple and blue from the transformer, to rewire it for 220v I should connect the white wire from the switch to brown...

I made recordings of the talks on Saturday for everyone who missed them.   2:00pm-3:00pm https://www.mixcloud.com/victor-low/canjam-sg-2017-chord-electronics-talk/   3:30pm-4:30pm https://www.mixcloud.com/victor-low/canjam-sg-2017-new-trends-of-portable-audio-talk/   5:00pm-6:00pm...

  I didn't check the footage while in Singapore and when I got back home found that large chunks were missing.   I edited together what I had and cut some of the fluff out to reduce the overall length.   I'm not happy with the way it turned out but I'm putting it up anyway for posterity's sake.
