Just finished this little baby for office use: a modified Kumisa III @ ±24V DC (with a couple of traces cut and some resistors changes). http://i72.photobucket.com/albums/i1...eelding443.jpg ... heavily heatsinking on the bottom, which allows quiescent current biasing at 60mA, http://i72.photobucket.com/albums/i1...I/RIMG0148.jpg ... and the guts http://i72.photobucket.com/albums/i1...I/RIMG0147.jpg I'm not good when it comes to describing the sound, but in short... a very musical, laid back sounding amp without any sign of distortions, noise, hiss or hum. It makes this hobby (DIY) so fun.
