hi friends,

I have spend whole my last weak with this amp and winding inductors.. finally I could able to remove all switching noise.. sound is so perfect now..very low heat (only got the noise coming out from my PC

) and I learnt a lot of things about inductors. there are many things to concern when winding an inductor. not an easy task and to explain just by a post.. I ended up with winding my core on a ferrite stick taken by an E core.. (The 'I' part of an E-core) It was the best result .. may be I couldn't find a required toroid in my country sadly. I will send you more pictures later.. I should sleep a day now at least because I haven't sleep well for a week i guess

regards,
Lycanlk

I ordered free samples from coilcraft for their class d audio toroids. They shipped out on thursday so i should have them in around a week and a half.
