RE: [vintagesynthrepair] Hammond H100

2008-04-06 by timothy kosiorek

I see this problem with a lot of Hammonds and I usually try to cure it without taking anything apart,the grease on the mechanism gets thick with age and keeps the bars under the keys from moving,the way I fix it is by squirting WD-40 beside the keys and pushing them up and down,use the little hose that comes with the WD-40 so you can shoot it all around the keys,the sticking mechanism is in the frontal part of the key,the WD-40 mixes with the grease and loosens it up,once you get the lock down bar to move go back and forth between the cancel key and the various preset keys,the volume should also return by rapidly moving the keys up and down because it usually is caused by dirty key contacts and the movement will clean the contacts,I've been fixing Hammonds this way for 30 years.only after trying this do I rarely have to get under the keys,if you have to get under them it is a bit of a project but only takes about an hour.

Tim K.
