Hi there. I have purchased the yamaha ex-42 organ recently but unfortunately the upper manual sounds not working. when all the sounds are off there is a sound like flute appear on the upper manual and when I change the sounds nothing change on upper manual. everything elese works fine. I heard that on this type of organ the capacitors most possibly cause this and need to be change but I don't know which one. There are too many capacitors inside. Would you please help me solve this problem. I really appreciated. In my country no one can fix this organ.

Hi, I own a Gulbransen E4 model. It needs to be tuned badly. It also recently developed a high pitched tone that is above the keyboard, but it stops altogether when I press the highest G on the great. I heard that it is possible to replace the oscillators to get rid of similar problems. What do you think? I can't afford to have an Organ technician replace the oscillators(or whatever they are). And I can't afford to just have it tuned if tuning doesn't get rid of that annoying high-pitched tone. I hope I'm not confusing you. I bought this organ a few years ago, and it's resale value isn't much, but it's worth a lot to me.Any help would be greatly appreciated. Thanks!

If you get a second?
Please look at my post re: 130 leslie to S08 Yamaha in Hammond organs I'm 99.9% sure i can do this but your opinion matters

Glad to help!

Thanks for the replies Geo! It really makes working on these old organs a lot more fun when you can get feedback so quickly from people with knowledge.
