Diy Headphone Amplifier Circuit. Cmoy headphone amplifier cmoy amp cmoy is a term derived from its inventor mr. The circuit i chose to use is the circuit seen here.
Add the positive leg on the 470uf capacitor to pin 5 on the ic 2. A small valued resistor at the output of the amplifier isolates the load and minimises any tendency of oscillation with long headphone leads. However i am going to provide my modified.
A small valued resistor at the output of the amplifier isolates the load and minimises any tendency of oscillation with long headphone leads.
The amplifiers need 15 to 24v regulated supplies at 160 100ma and 6 3v dc at 300ma for the tube heater. The signal out of ic1 at pin 1. Which we set form circuit to become the non inverting circuit. The result is the eb 804 421 a single ended se pure class a amplifier capable of driving headphones between 32 and 600ω.
