philetaylor Posted November 14, 2009 Report Share Posted November 14, 2009 Hi. The BA662A is pretty rare nowadays... You may be better off using the (almost) identical BA6110. It is a bit quieter but very similar otherwise. There are loads of BA6110's on ebay. This website has a good description of the differences: http://www.subatomicglue.com/x0xl0g/ba662a-analysis/index.html What it doesn't mention is that two of the pins are swapped so a slight mod would be needed to the board, I can't remember which ones but the datasheets should tell you.

kroutshev Posted November 14, 2009 Author Report Share Posted November 14, 2009 Hi Phil, i have already read it and it's very interesting but it's not for make a clone but to replace defect part into my old gear and that's why i'm looking for BA662A and not BA6110. Thanks. Quote Link to comment Share on other sites More sharing options...
