    Wurlitzer 4140 service manual. I have the schematic and know how to read them I just do not know the flow of the audio and need some help on how to trace things through. I am an Electrical Engineer but have not worked on any organs. I bought this organ for my daughter when she was 12 yeares old back in 1962 and need some info on how to get the pedals to work as they do not have any audio from any of the pedals. All voltages seem to be correct but am lost as to where the audio is produced and past to the generator.
    Thanks
    Tony

    Looking for a service manual and/or a schematic for a Baldwin Cinema 2 Model 214. We think it has a problem with the power supply, or amp and are trying to debug it.

    Thanks in advance.

    Someone is in possession of the wiring diagrams of the Viscount C160 Grand class? I'd need it to try and repair it.

    Thanks Andrea
