Hello everyone. I need some help to fix my farfisa. Percussion.The percussion works. But at the end the direct sound disappears completely. It may be normal. Problem : All keys of the keyboard work this way except one. On this key, percussion is correct one time. Then the key is disabled and takes a long time to return. I do not understand why since without percussion, this key seems normal. Triming of the percussion electronic board may be necessary ? Brilliant.The key has no effect. It must not be too difficult to find. Reverb.I'm looking for a Tesal W3 stereo piezo cell. This is the Drive cell that is damaged. In short circuit on the 2 stereo channels. In general the Receipt cell is in good condition. Very fraglie. To remove. Cut the wires. Unsolder the Reverb spring. Bend the front socket.

Percussion (Solved).As '16 '8 '4 drawbars are one way contact, Percussion is a two way contact. NO and NC with the Common connected to a capacitor and then the busbar. If one of this contacts is dirty the percussion don't work properly = don't trigger or dead time after triggering. I clean it with contact cleaner and adjust the lever if necessary and it works. To do this, the Hameg component tester is perfect. Brilliant (Solved).This key is effective only if with the right 2 2/3 key. Reverb. I'm still looking for a Tesal W3 stereo piezo cell.This is the Drive cell that is damaged. In short circuit on the 2 stereo channels. In general the Receipt cell is in good condition. Very fraglie. To remove. Cut the wires. Unsolder the Reverb spring. Bend the front socket.
