After reading a thread in 2010 about MCD-255 class-D amp I got curious. In April 2011 I received 4pcs from China.
Unfortunately only one survived me measuring upon them. The three others just instantly (ns?) burnt
... Fet's measure Zero ohms in all directions.
Due to an accident I had to let it be until today. When I now look at the boards Fet and gate drivers I find the marking been brutely grinded off from the plastic.
The vendor has not been answering since I sent pictures on ringing outputs. See attach1. The vendor is no longer member of the forum.
Can someone out there advice me how to do to rescue my amps
? My goal is to have them placed under my cover, attach2.

Tekko you are quite right. I just got an answer and DYI products is no more a part of his business. Never the less I am told I will get support to solve my issue.
How lucky I am being a part of this great forum! The previous picture was a design with 4 class D amps, Xo and PS for the drivers in attached picture. Including a remote controlled laser and speaker top module for sweet spot alignment.
Sounds good and perhaps better with the MCD in place! I'll keep the forum informed.
