I need some help. Here's the story:
I just picked up a Wurlitzer student electronic piano (from 1979, I'm told), similar to the one pictured here:
http://www.keyboardmuseum.org/ar/w/wurl/206.html
This keyboard was meant to run off of a master power source along with the other student pianos, which I obviously can't accomodate.
To get my own power, I bought an power cable that was pre-split into + and - (black and white). I opened the lower compartment of the keyboard and, from the black and white cables, made a "T" split to the new power cable.
Power is up and it seems to be working well except for some dirt/static that comes through the speakers from time to time. To troubleshoot, I played with the split that I made, moved the power cable far away from the other cables and nothing seems to make a difference.
The splits that I made are well isolated from each other. The dirty sound is not affected by turning the volume knob up or down or playing the piano.
So, could the dirt be the result of my split? Am I doing a bad thing be hooking up power this way? Should I let a real keyboard repair man take a look at it and let him hook up the power?
Also, there is a green cable in the keyboard. Is this the ground? Should I try this with a three prong power cable?
Is there a God out there or are we all alone? (Since I'm already asking questions...
)
Any help is appreciated.
