Help replacing phone jack and filter caps on CRB Diamond

[Guest]

Hi everyone!</p>


I really need your help: I have a CRB Diamond 807 which I really like because it sounds great in my house - and lounge music. But the headphone jack, which is very important since it is the only way I can plug the organ to my mixer, sounds very bad, when I use it there is this "airplane" sound all the time, it's a constant noise. Another problem that occurs, even if I'm using nothing but the build-in speaker, is this 60 Hz humming sound all the time, making my recordings useless in my songs.</p>


I think these two problems is caused by two things: I need to replace the headphone jack and the filter caps.</p>


The jack is very rusty as you can see on this pic, and must be replaced in order to work:</p>

It is the only thing in the entire organ that is rusty or damaged. The cables from the organ is mounted 5 places on the jack socket. Does anyone know where I can buy these sockets, or something like it?</p>

Another problem, which is probably causing the humming 60Hz sound, is the filter caps which must be replaced. But what is the filter caps? I am not sure how to locate them. Is this the filter caps? (thestriped ones with two legs):</p>

Does anyone know where I can buy these filter caps? I don't hope the striped ones are filter caps cuz there are LOTS of them (I'm talking almost 100)</p>

Sorry for all my questions, I just wish my organ worked well.</p>



Thanks!</p>

I think you're getting your caps mixed up. A constant 60Hz mains hum is probably caused by the filter caps in the power supply, not the small caps in what looks like the oscillators in your photo. From a safety point of view,if you're not surewhatthe filter caps looks like or where they are,I'd say that it isn't a great idea for you to change these yourself. Get a tech to do this, there are lethal voltages involved and if you get things wrong, there is a seriousrisk of blowing up the power supply - and yourself.</P>


And the output from that socket is for headphones. If it's not broken, then I guess that just thatthe ouput just doesn't match your mixer.</P>

Thanks a lot for your reply! Yes I've heard that filter caps are quite dangerous. I think you're right about letting a tech do it. The problem is that I don't know any instrument techs near my home :-(</p>

The headphone socket has this weird "airplane" sound even if I just use headphones, then I can hear the sound in the headphones. It's the same problem with phones as with my mixer. It is very rusty, I think that's the reason. I just can't find any jack sockets where you can connect 5 cables from the organ (I think it's because the organ has several speakers inside), only 2-4-6 connectors.
