Description

Class-A Headphone Amplifier using IRF610 and LM317 as CCS. The original project and overall idea is to this guy.

Note: Only one channel is shown.Please, also note that the 100k trimmer resistor should be adjusted - see diyaudioprojects.com for more information about that.

Be careful when connecting LM317 and IRF610 - my labels may be confusing.
