I have used those 4-connection universal adapters, I've noticed one pin seems to fit but doesn't actually make good contact while another fits well.

I have just realized that both of the power adapters I've been using for my CZ keyboards are not actually working. I've been actually using the batteries which have been slowly running down. They are 9v adapters... but perhaps the pin-size is not correct and they are therefore not actually fitting correctly? I think I bought them by searching Amazon for "Casio CZ power adapter". Can anyone recommend an adapter for sale that they know actually works?
