This means the preamp stage has DC. Get a meter out and measure it. There are trimpots to adjust it - if it isn't too far off (less than 0.1 volts). If it's more than that, the preamp stage itself has a problem. Also, make sure your power supply rails are even (+/- the same).

    There isn't any service manual available unfortunately. In fact, I don't think we ever had one.
    
    What are you trying to do?
