  • Conn Theater 650 - no reeds.

    Hi all. I just picked up a Conn 650 in beautiful cosmetic shape for free. When I got it home and plugged it in I found only the Tibia tabs worked. It came with the service manual but it's a little over my head. I understand some of it but it's going to be a steep learning curve. I was hoping someone might have an idea what's wrong with it. The sounds that work, work well. Only the tabs that use the Tibia solenoid work, all others are dead except for a very weak effort on the Vox Humana. It's the same with all keyboards and the pedals. Any and all help is appreciated Thanks.

    See page 30 "Maintenance" on how to open the top.
    Locate the post amplifier circuit board. (Figure 76 on page 66)
    Try moving the complex level control. If that doesn't bring back the sound then do a hum test. With the organ on, touch the inputs and outputs (Shielded wires) with a finger. You should get hum at all four points.
    Report back.
