HELP!! Ace-Tone GT7 Organ

[crj007]

Hi
Can anyone help.

I am trying to locate a wiring diagram for the Ace-Tone GT-7 portable organ. Acetone was bought out by Roland in the 70's.

I have been onto Roland and they were very helpful but did not have such wiring diagrams.

The problem with the organ is that the pedal board does not work. The expression pedal is working fine but that actual pedals do not produce a sound.

Any feedback would be much appreciated.

Thanks
