Broken capacitor on old keyboard.

[Kits]

Hi there.

Recently I pulled my old Yamaha PF-15 Electronic keyboard out of storage. I opened it up to see what was actually inside and I saw that a little rectangular component on the power supply board was bulging and had cracked, I powered up the keyboard and it worked! Apart from a few keys on the lower end. After about two weeks of use the keyboard started to make some really odd sounds when I press a key, occasionally the note being played sounds really warped like a cassette tape left in the sun too long.

I think the broken rectangle on the power supply is a capacitor because it says 0.022uF on it. All the other capacitors are fine.
And since it was made in 1981, I think finding replacement components might be quite hard.

How would I go about fixing this? I can solder but not very well. And I don't have much money.
Sorry if this post is in the wrong place. I don't really know where to put it. Also it's my first time posting on a forum.

As long as you match the capacitance and the voltage is the same or higher than the original one, you will be fine.

Do you have detail on the voltage of the capacitor?

You can, if you have a multimeter, measure the voltage across the capacitor.

If you don't know, just use one with a high max voltage rating so it won't burn out.

The capacitor is cheap (less than $1):

Basic electronic components like capacity haven't really change that much. Only the high end stuff like computer processor, ultra capacitor, LCD display and batteries change a lot.

And yes, this is the correct place for this question.

Okay, good to know that I don't have to scrap the keyboard. (And I got the right place to post this)
I think the capacitor might be what looks like a MKT capacitor. I don't know how to upload pictures.
On the side of the capacitor it says 250V~MP 125VAC IEC 65 GP5 and I think the brand is RIFA.
Also, the capacitor on the Jaycar website is rated for 100V, would it still work?

The 630v cap on that page will be enough to handle the voltage, not the 100v.

Whoops, I missed that one. It doesn't look like the one in the keyboard but the 100V one does. So are you sure it would work? I just don't want to solder it in to find it doesn't work.

The 630v cap doesn't look like the original cap because it is in a wrap package. The 100v cap is in a box package.

Thanks for the help Pyree! I'll be replacing it soon as the keyboard is unplayable now.
