huangyong 0 Report post Posted December 5, 2005 this is my old project in a brand new body. it used to live in bread board, now reborn onto a tiny piece of PCB and lives happily in mint tin. it is basically a cmoy, with 1uF WIMA input cap and has a gain of 4. You must have noticed there's another opamp behind cmoy, it is sijosae's style virtual ground. the old pot is having problem serving me.. so it gonna be replaced by an alps soon.
