A quickee look and see...
Bought 9 years ago used, no rebuild, no repairs, no faults. Serial number indicates 2005 build date.
Left monoblock, approximately 5W/4Ohm tone, loaded by the speakers:
Not great...
Left Channel.
695 more rated watts available, though.
Let's see:
THD 0.012% = -78dB
Noise 0.091% = -61dB
Maybe adjust by 2.5dB since the signal wasn't full-scale, if you like.
Should investigate the inaudible power fundamental and harmonics.
At least the harmonics don't look like some of the very low priced stuff*.
Then again, the speakers distort more than the amp, and the room is noisier...
Yup.
THD 0.21% = -53.5dB
Noise 3.66% = -28dB
