(The prediction data of the amplifier)
The frequency of this amplifier is very wide.
10Hz - 100,000Hz (-1dB, 1W,non-NFB)
10Hz - 250,000Hz (-3dB, 1W,non-NFB)
The S/N ratio of this amplifier is very high.

-Out-put-
non-NFB:Stereo 8ohm(about 7W+7W) , Monaural 8ohm(about 16W)
   NFB:Stereo 8ohm(about 9W+9W) , Monaural 8ohm(about 22W) 4ohm(about 18W)
(I plan the changeover switch of a stereo amplifier and a monaural amplifier.)
