I recently got a Kimball Swinger 1000 for free from craigslist and after i plugged the thing in, it only makes feedback noises when the keys are struck. Same when headphones are plugged in. The lights, pedal and motor work still. I'm not sure about the pedal keys Im sure its just a minor problem but I know nothing about organs so anything you can tell me will help. i can send pictures if needed. thanks! -Ralf

Kimball piano values vary based on age and condition; as of 2015, many uprights sell for $10,000 or more. Kimball is a well-known brand, and several of its antique pianos are considered highly collectible.
The Kimball Piano Company, based in Chicago, was one of the largest piano manufacturers in the world. At the turn of the century, Kimball built approximately 20,000 pianos annually. Kimball produced pianos under different brand names such as Hinze, Dunbar, Whitney and Harrison. Styles were influenced by Victorian, Greek Revival and Arts and Crafts architecture, and upright models were often available as player pianos. Kimball was sold to the Jasper American Corporation in 1959, and its pianos were discontinued in 1996.

have you tried google or even ebay

A bad ground connection?. Try tightening the nut on the phono plug first. You can pull out that section where the cable hooks into and visually check the solder connections.

This will not be a user serviceable problem. Call in your local organ repairman.

The information on http://www.bluebookofpianos.com/kimball.htm indicates that serial numbers between 488000 - 499999 were produced in 1947.

Try changing the configurations to your desired effect.

Yes, there are several possibilities. First thing is to disconnect your guitar and then plug in the cord to the amp. Expect a bit of hum. If it screeches, then problem is not feedback via the guitar. If it doesn't MAYBE your guitar is "hearing the amp" which the guitar is then a microphone and can feedback. Moving the cable generates electrical noise which can trigger the feedback to start.
If you get the screech without the guitar connected, then TRY a new guitar cable. Make sure it is an INSTRUMENT cable... I have seen some try to use speaker cables or junky 1/4 inch cables intended for home stereo... these will NOT work and can cause the feedback. The next possibility is a broken jack on the amp. This would require repair. The common cause of this is to fail to run the cord through the handle of the amp... one trip on the cord or step on it pulling the plug sideways in the amp and the jack is broken and it is a trip to the shop as well. While on the subject ALWAYS run the cord at the guitar end either through the strap or your belt loop. Cords left dangling keep rotating and soon wear out the plug and also the jack in the guitar and then that has to go to the shop.
