Kimball Organ Update! Hi. New videos will be uploaded 'soon'. Until then, i have some interesting experiences to share with all if you! Most of it still works from the previous videos. A few thinks are still broken, and a few other things broke recently....
1. The Syntha-Brass II sounds never worked and i am planning to fix it. In photo 1 is where the signal from the solo voice board does work. The test leads are to a signal tracer. After it goes through an op-amp chip, there is no signal. Part no. is MC1458P. I acquired the service manual from Organ Forum, which made tracking the fault easy.
2. The drum machine entertainer rhythm makes a loud tone when it is very cold. It is winter now, but it is now in the only room in my house with a heater, so i haven't experienced the problem lately.
3. The low C key on the accompaniment keyboard broke. All keys contact a 'buss bar' with a j-wire (a spring, see photo 2). That has snapped, so i need to repair it.
4. Some random keys that i don't use on the solo keyboard broke. Not the same issue. Maybe diodes, oscillator problem, or a failing processor chip.
5. Leslie speaker rattles a bit. Looks unbalanced. Tightened the belt and oiled the drum and motor, but this did not do anything.
Apart from that, most things work and is fun to play. I am learning how to play organ and i never regretted picking this old instrument off of the side of the road!
