It would be nice to have screw terminals for the input instead of the input jack.

-the device is easy to use -strong noise at 1W output power
-a lot of harmonics
-screw terminal is made out of cheap material, it should be replaced by a dc power connector A low pass should be placed at the output, this amplifier creates a lot of interfering signal, you should also use it in a case ... Read more
