Dead PS board in DX7

2007-10-21 by . g . n . w .

Hello Folks,

I recently acquired a free DX7FD-II, and it has a dead power supply board.  There is no 
voltage at any of the outputs.  The switch and on-board fuse both test OK.  Does anyone 
know of a source for replacement boards, or have any suggestions on testing this one 
further?  I have a multimeter and scope, but I'm not clear on what to check.  Any thoughts or 
suggestions would be appreciated!

Thanks,

George
