Hello OZ4,
Wow nice job and like Ron I too have used that LM4500 and also would like to build a new one to use with a old tube Harmon Kardon Receiver .
Well Ron I think Chris might have done the leg work for use finding this IC .
Anyway OZ4 you did outstanding job and what great old Sony .
to use the software to design a circuit board nowadays is a lot simpler then when I was designing boards back in the 80s and 90s .
Sincerely Richard
