I took an old Dynaco Stereo 120 Power amp, and made some PCB's to retrofit LM3886s. I've attached a picture of the first completed version. I haven't listened to it yet, but the quick measurements so far:
*a bit more than 60 Watts into 8 Ohms before it clips
*harmonics of 1 kHz better than 80 dB below the fundamental below clipping
*3 dB frequencies of 10 Hz and 100 kHz
*about 1.1 Vrms input for full power output
The insides look a bit nicer than they used to, I think...Hopefully I can set it up for some listening in the near future. (picture is just a quick snap from my cell phone camera).
