My Hammond E-112 has a broken percussion unit. Fortunatley I have allllll of the diagrams and schematics for the machine. Unfortunatley electronics is not really my field so I am not very good at reading them. Anyone who knows electronics and or hopefully specialises in Hammonds. Even if you want to help me tune the machine up I would be happy to pay you. I can send all the charts/schematics ahead of time for you to review Description of the problem: - Percussion unit is always playing the 8' and 2' notes on the top keyboard, even when all of the percussion tabs are off - These notes go away when I turn down the percussion level in the back of the organ - When I use the percussion tabs, the sounds they make do not decay. So if I push in all of the draw bars and just use the percussion, it creates a constant tone instead of a tone with a sharp attack and then a fast decay - The reiterate tab does nothing at all... I am unsure if this is related or not - The crash/symbol percussion works just fine, it just sounds bad so I don't use it I love my Hammond, aside from this it works very well. I wouldn't be supprised if it was just a busted capacitor or a shorted connection. Any help is appreciated
