A few weeks back I wrote up a blog about the Doublet Headphone Amplifier which lets two people listen to the same audio source with independent volume controls. I got so many emails from folks who were interested in building one that I decided to make another run of the printed circuit boards – and they’ve arrived!

If you want one of the PCBs, email me with your mailing address and I’ll drop one in the mail to you at no charge. You’ll have to supply the parts and the Altoids tin.

  1. Awesome, I just emailed him trying to pick one up, I’ll document the build process if I get a hold of one and report on the sound quality, the boards look very very nice, can’t wait to hear back from him

  2. Sam has a real useful search engine tied to electronics suppliers, octopart He’s looking for places to promote it as well, I’m trying to put together a list of Ham sites for him. Everyone should pitch in and give him a hand as a thank you for making finding parts a little easier.

  3. can anyone tell me the email address to email about getting a bare board. because outlook wont work on my computer so every time i click the “email me” link an error comes up
