    Ground Hum-Hammond A-100 w/ Leslie 251



    Hi.... I'm experiencing a Ground Hum with a Hammond A-100 w/ Leslie 251 that has a three way switch (chorale, brake and tremelo) when the switch is set to chorale (slow speed). I've tried different room positions and outlets with the leslie and the organ. Next week I have a new cable coming that I can try. Any other possible tips or suggestions?</p>

    Thanks for your help and suggestions?

    If a Leslie is placed too close to the bass end of a Hammond, the motors will radiate hum into the matching transformer. The slow motors are louder than the fast ones.</p>
