Request for help

'We have an old electric organ that belonged to my wife’s grandfather. Although it is not an instrument worthy of the attention of this illustrious group, we would like to get it serviced somehow. The pedal has a cypher. My wife has started learning the organ and this would be a useful practice instrument. Can any electronically minded member help?'

The details of the instrument are attached - in German, but I think giving sufficient information to anyone who may be able to help. It is thought to date from about 1960.
