[QUOTE="tangmonster, post: 99401, member: 1581"] Hi there i have built a test circuit on strip board of that headphone amplifier a circuit very similar to that one: http://www.avforums.co.za/index.php/topic,7070.0.html I did not like the lm317 as a current source so I opt for the simpler resistor option. I did however add a lm555 and relay timer at the output since large dc flows on startup and shutdown. Spent lots of time with rc circuits to get it better but in the end opt out for a relay timer and the output. Go ahead , build it, and play! [/QUOTE]
