The curved traces were because the layouts were done with black "crepe" tape on Mylar. Curves are easy to do. That was superseded by red/blue Mylar tape which does not do curves. In short, for audio frequencies there will be no difference. A good two layer or multilayer board would way outperform anything from the 1970's. <br><br><div dir="ltr">Sent from my iPhone</div><div dir="ltr"><br><blockquote type="cite">On Feb 14, 2020, at 2:10 PM, Harry <hbissell@wowway.com> wrote:<br><br></blockquote></div><blockquote type="cite"><div dir="ltr"><meta http-equiv="content-type" content="text/html; charset=utf-8"><br><br><div dir="ltr">Sent from my iPhone</div><div dir="ltr"><br><blockquote type="cite">On Feb 14, 2020, at 1:50 PM, Jimmy Moore <jamoore84@gmail.com> wrote:<br><br></blockquote></div><blockquote type="cite"><div dir="ltr"><div dir="ltr">This came up on the AH "behringer RD-6" thread:<div><br></div><div>>>Until the PCB traces are curvy (like on a 2600 or SEM) it's never going to sound authentic.
