Title: Any hammond technican out here?
Post by: SHORTHAND on March 29, 2011, 02:46:16 PM
When I pull out certain draw bars and I play a B note or E note it makes a annoying sound. When I first turn the organ on I don't have that problem. Sometimes about 30 mins later it does it. What can I do to fix the problem? The closes technician for is about 2 hours away. It cost me more just him to come out than to fix the problem. Any tips?

Thanks, I will. It sounds like its two notes hitting at the same time. And when it does it, it sounds like the motor is slowing down.

Definitely sounds like a problem with a particular tonewheel in the generator, especially if there are changes in pitch on that particular note. My Hammond CV, in the past, has occasionally started making a grinding noise and the pitch of a certain tone would fluctuate. Your problem very possibly could require the tonewheel generator to be removed to further investigate the root of the problem.

you're back bro!! great,have missed ya RMS!!!

by chance-have you moved the organ recently?? there's 4 big bolts that need to be tight if you move it,with the organ off-lie on you're back-look up above the pedal board.

Tighten and then un-tighten all 4 equally.Then;take the back off-make sure the springs that hold the generator are free.Fire the organ up-see if that helps.

Don't put your hand in the organ with it running-unless you know what you're touching!!!unless you want to see what you can fry

What kind of organ? What year? Sounds lithe a generator problem which would translate into forking out big money for a complete rebuild or purchasing a organ that had been rebuilt.
