Perfect replacement
It worked perfectly on my old Casio keyboard. It has the negative center pin which is not the norm for most wallwarts.

Excellent dual channel high-freq scope for the hobbiest.
I decided to get this used analog scope because of capability, cost and ease of use. Unlike digital lower cost USB scopes - everything is in one package. All the capability you expect is there. I will use this to develop projects on my RPI and to troubleshoot all my ailing electronics. I got a good set of compatible probes on Amazon. The manual is available on line. If you have never used a scope before, search for online tutorials as the many capabilities this unit has can be daunting to the newbie.
