LME49810 300 W amp kit from TaoBao (Mods)

Posted 23rd September 2011 at 07:19 AM by panson_hk

The THD performance of this board can be improved by separate the input/NFB ground from the decoupling grounds. This is a common mistake in many kits.

Simply cut the trace as shown in the figure and connect the input/NFB ground to supply ground via a separate wire. THD improves as shown in the figure.

    Can you comment on the quality of this amp? Also, why did you add the capacitor?

    Apologies for bumping an old thread.
