Wireing Diagram for Ramsa(panasonic) WP-9220

[Claus Hollen]

Hey All

I've been given a Ramsa(panasonic) WP-9220 PA.
My problem is, it runs on 120v 60Hz, and i get 220v 50Hz, i have step
up transformer, but it only gives 110v 50Hz. The Amp Is surpose to
give 300w @ 4ohms.
But i feels like it's missing more than a few of the 300W.

So im looking for a new transformer, but need the diagrams for an
exact match.

Thanks in advance.
