Cmoy under the hood
I've showcased my 3 favorite Cmoy amps. The first point to point Altoid amp was my first attempt. I spent an entire Sunday afternoon getting this together including troubleshooting. the larger one is also a Cmoy amp with an 18 volt power supply and a crossfeed circuit-hence the two additonal switches. The last Altoids amp was built form a PC board I bought from a guy on Ebay. It also includes a rail splitter power supply and a bass boost circuit. I don't need the boost for my regular headphones, but the Shure earphones could use the help.
I also have completed a SOHA tube headphone amp, but you will have to tune in next time to see this one. Also on deck is a class A Tube headphone amp and a Dynaco 70 upgrade.
