Request for Pioneer schematic assistance

    I have consolidated and cleaned a couple of Pioneer original schematics for some older models, and would appreciate if anyone working on these models could verify the interconnections and critical device numbers shown on the re-formatted schematics. As more documents are updated I can post them here.

    The longer I look the more I might find
    SX-828, L7 has no value, CT2,3,4 have no value, in the FM FE, underneath CT1 there is 0.005 which is orphan. Is L2 supposed to have a value?
    protection, Q7, 2sc945?
