alvin1118 0 Report post Posted April 2, 2008 hm...i would say i'm rather busy these few days, fully packed! but i cant stop DIY-ing! it's just like something must do in life even i have no spare time for it. maybe that is so called: hobby? lol LC-ICUTE, separated out from my integrated amp. 1st intension is i need this headphone amp to drive my A900 i have tried a few OPA, finally find that LM4562/OPA2132P sounds better in this circuit design structure.

ganggang 0 Report post Posted April 25, 2008 This looks really nice Alvin. I must say that your projects set High Standards. Is that Silver wire runing into the half bridges? Can I ask where do you source your equipment from? eg Toroidal transformer? I bought mine (non-audio) from WECL in HKG, shorted it and now i am stuck. My first project (humble-humble) is to setup a PSU for my T-amp and just rebox into something nice. Next is a passive pre-amp. I am considering a Aikido PCB from glassware, trying to get a few orders together... any interest? Share this post Link to post Share on other sites
