Another prob is the amp is not EARTH, sometimes when touching the casing, i can feel the SENSATION rolleyes.gif, which feel so irritating...

 

So, mod mod mod.... connect the casing to the earth.

hey, i feel safer when touching it, at least i know i wont die even when the current leaks, coz the resistance from casing to earth point is 0.2ohm....wahahahaha w00t.gifw00t.gifw00t.gifw00t.gifw00t.gifw00t.gif

now, the culprit for the hiss s hte thin and unshielded wire, just change it to a normal shielded cable and it sounds really nice.. no hiss or noise any more...

i think maybe the fact theyre to92 will limit the heatsink choices you have that can be effective, simply thermally bonding to the top may not yield optimum results. why not simply wind down the bias to a more stable level and save the big current bias for dynahi wink.gif
