    Kenwood Basic C2: Extra Diodes and Missing Qs in Op-Amp Power Supplies

    Interesting note is that I have found several places indicating that the NJM4560 and NJM4580 are not pin out compatible?? Has anyone else verified their interchangeability?

    Kenwood Basic C2 recap BOM

    Does anyone know the primary difference between the MM and MC phono sections in the C2? Does the MC have any additional amplification of the signal due the lower output nature of MC cartridges? There is no real explanation in the manual outside the impedance matching settings.
