Presenting Ze Cube : a vintage computer (the Macintosh Classic II) miraculously engineered into a stunning ten-inch crystal-clear cube.
But, Ze Cube is making NOISE !
It starts as a low pitch noise getting slowly higher, and higher, and then so high you can't hear it anymore. Then it's slowly coming down lower, and lower, and lower until it's, well, very low. Then it's getting slowly higher, and higher...
Maybe it's a capacitor leaking. Wich one ? What to do about it ?
What else could it be ?
Any ideas ???
