    Hello,

    i need a service manual for my Yamaha C6.
    If somebody has one, please tell me a price. Please lower then 13 $/Euro.
    I want my C6 back to live. It was my first Amp from my first own money.

    Thank you for your support.

    E-mail Norman at analogalley.com. He is my go-to for extremely HQ color pdf files. Just tell Norman what you need. ie Yamaha C-6 service manual. They run $13-15

    What kind of issues are you having with your C-6 ? I've worked on maybe six or more over the past few years.

    Hello avionic,

    thank you for your response.
    The C6 has no sound, the lights are on, and the 12/-12 V and 31/-31 V from the transformer are exist. I need the voltage on different points to check different parts on the circuit board. I am a amateur and burn a fuse, while checking parts with a multimeter. (but i can use a soldering iron). A service manual is the best for me with a chance to bring this C6 back to live.

    I know this link. I search some hours for a manual online.
    I spent 5 dollar for a copy, wich is readable but not 13-22 Dollar. It is a little to much for repair only one C6.

    Sorry for my bad english.

    Make sure your reed relays RY101 and RY401 are working. From a cold start, you should be able to hear a "tink" sound from both relays a second or two after power on. Have to get your ear down close to them. Check all the fusible resistors.

    It is a very, very faint " click". To hear it. You have to have your ear real close to the relay.:thumbsup:

    An empty paper towel tube is perfect for this. An useful tool that is always on my workbench.
