Hi folks
I'm having a debate with a friend over the chorus schematics from the CS80's main diagram, so I need some help from anybody who remembers how the circutry in the PCB is actually made: the debate concerns the dry signal to the inputs of the MN3001 IC. I believe that the schematics are drawn well, when I see that the dry signal is sent to both IN and IN' inputs of the BBD, while keeping the phasing on through the output of the first BBD line to the input of the second. My friend thinks that the schematics have some errors: he tells that the dry signal can't be delivered to both lines at once, because if the pin next to the dry signal's cable was real, the dry signal would have bypassed the BBD, so the signal is delivered to line 1 then line 2 through the line 1's output.
Can anybody shed some light on this? David? Christopher? Anybody else?
Thanks for your replies...
M
