A few years ago, I took my Roland XP‑50 to a repair shop to have the capacitors replaced. They replaced all of them, but from what I remember, they used the same values for every capacitor (I don’t recall the exact values right now).
The keyboard powers on and works, but it now takes longer to start up. Also, when I press the keys harder, the sound/volume actually drops, which makes it very difficult to use.
Fortunately, I took photos of the board before the replacement, so I can see the original capacitor values.
My question is: where is the best place to buy the correct replacement capacitors? I’ve looked on Amazon and eBay, but I see different shapes and types available, and I’m not sure whether the shape matters.
Any guidance would be greatly appreciated. Thanks!
