I recently decided to build a CMoy amplifier, in an Altoids tin, because I'm the kind of man who wears headphones large enough that they can't be optimally driven by an iPod or laptop's audio output. A new pair of headphones I've had my eye on a while are 32Ω impedance, which is for sure too high not to use an amplifier if you're listening on a laptop. Whatever. I decided to build an amp. While shopping for parts for this amplifier I want to build, seeing so many Chinese manufacturers' products, I started thinking of the goings on in Shenzhen, China, of late. The Foxconn factories have been in the news lately for their atrocious labour standards and the rampant mistreatment of their workers, and it's made me feel absolutely shitty about myself. I'm typing this, right now, on a MacBook Pro containing many parts manufactured originally in Shenzhen. My iPad was completely assembled there at the Foxconn factory; its only American-made part as far as I know is a glass screen made by Corning, the bezel for which is also made in China. I've spent enough time feeling guilty and awful about myself; I decided it was time for action.
It took probably twice as long than if I had merely bought the cheapest parts and been done with it, but I took the time to source 100% of the resistors, capacitors, integrated circuit chips, connectors, and potentiometers for building the CMoy from United States-based manufacturers. The resistors are all from Xicon, in Texas; the capacitors are from Xicon and Cornell Dubilier, of South Carolina; stereo volume control from Bourns, of Riverside, CA; stereo headphone jacks from Switchcraft right here in sunny Chicago, IL; and integrated circuit chips from Texas Instruments in, well, Texas I'm assuming. It took a little bit of effort but I have made the list of parts, as a project on Mouser Electronics' website, available for anyone to use if they want to build a CMoy amplifier with a minimum of drama and use only US-sourced parts.
