Nice little Class 'D'...............Glad it works as planned....Do you have any specs on it...performance parameters perhaps.
Just who is this other site & why are they so adamant toward not sharing information? The greatness of internet forums, regardless of the field of interest , is a free exchange of information..............an open book if you will. Commercial interests are few & far between as the likely-hood of profit is extremely thin within this industry.
