I have recently repaired 3x Casio DH 100 and 200. These (toy) digital horns from the 80s are cult and can also be connected to other sound generators via the MIDI Out - mega fun.

I can't play the saxophone at all, but you get to grips with these instruments relatively quickly. They are real sound machines, I was really surprised by these plastic bomber!![Love :love: :love:](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
As for repairs, they all have the same problem most of the time - they just start to uncontrolled squeak after a while.
The culprit is a small SMT capacitor that dries out and really stinks like hell when removed - a really disgusting fishy smell. I've never had it this bad, only my special acetone (nail polish remover with perfume in it) helps.![Cool :cool: :cool:](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)

The capacitor C39 is a 33uf type with 63V, but less voltage is also possible. You don't need a SMT replacement, normal TTH cap also works, as there are plated-through holes next to the solder pads.

Easy fix but heads up, do not mess up the screw head of the countersunk screw at the lower end! Big PIA.
