Rhodes Chroma Polaris

Dear Paul ,
May you give me the exact Z53 chip code ?
Do you think it should be easy to find ?

In the input jack area I see a brown cable coming from the preamplifier board ( LM384 ) that it is unconnected , do you think it is this the reason that Polaris stop playing sounds ?

Thanks .

Grazie 

Faelli Mario
