It would help if we knew what Lowrey you have! Let us know the model number (look for a makers plate at the back or under the keyboards at the front) or post a photo so we know what we're dealing with.
I'm assuming that you have turned on some voices for the lower and pedals? (you wouldn't be the first.....)
As for where to go for more help, join the Lowrey Yahoo Group here:
You'll find a lot of people there who know about restoration of Lowrey organs. You'll need to post a photo there, but once you've joined the group you can start your own photo album so that's easy.
