  • Looking for schematics of early C-Scope IB-300

    Hello all,
    I have bought an old C-Scope IB-300 of the mid 70's, that doesn't work when connecting the batteries. It is the model without an integrated loudspeaker, but having yet the 8" (20,5 cm) ISOCON coil. I am also owning a later C-Scope-IB 300 in nearly mint condition that works perfectly well. It's circuit board is quite different from the previous model. By the way, the circuit board of the latest IB-300 is same as the one of the C-Scope TR-400!
    I am looking now for the schematics (and the wiring drawings) of the earlier C-Scope IB-300.
    Can anyone in this forum help me?
    Kind regards,
    André
