Hammond D152 percussion problem

[Guest]

I have a D152 with a percussion problem.  When I first switch it on, the percussion will sound on only the first key pressed after the percussion was still on.  Then, nothing.  Does anyone know how I can fix this problem?  Thanks!

It is monophonic. You have to release the key before it will retrigger.

I know it's monophonic, but even if I release a key, it never retriggers.</P>

Dendrite build up. You need to apply a small amount of voltage (one or two9 Volt batteries or a model railroad power pack/transformer) to ground (amplifier chassis) and the K terminal (usually a blue wire) of the preamp. Do it with percussion engaged and disengaged. Some people use DC High Voltage from the organ itself but THERE IS NO REASON TO DO THIS! </P>


Also make sure your organ has been unplugged for awhile before working on it. </P>
