Audio Systems: alpine 11 band equalizer sound field controller 3342, plug connectors, model id

Question
dose anyone know where i can get a powersupply pluge

Answer
Try this company:

Maybe your part is listed in the link above.  

You may find a shop that has spare plug/connectors or can replace with a generic one.

I don't know this model so my replay is generic.  If you could obtain the service manual it will have a view of the chassis and parts list for all electrical and mechanical parts.

Hope this helps.
