Mongrel Dog Audio/Oatley JAN6418/LM1875 chip amp kit

The near complete build of the K281 Oatley Electronics Jan6418/LM1875 power amp. The K281 kit has been built as a dual mono construction with two separate amp modules and two 24V switch mode power supplies. This was an "out-of-the-box" build with no upgrade components or "fancy" build techniques. I wanted to see what the amp would sound like with no mods at all and employing a really plane build. It is very good. Holographic sound stage from a very believable tube and chip amp. The chip is capable of better than 20Ws. Next build.

    This looks very good. Does the Jan6418 have any ringing issues in this build?

    I followed your experience with Oately Jan6418 phono stage. I loved the sound of that phono stage - thought it was unique but still haven't been able to get rid of the ringing. I've tried lots of things but the ringing always comes in after 5-10 minutes of playing.
