Graaf 5050 Schematic

Hi

Just came across your posting & wondered if you ever had any luck in unearthing a set of drawings for the Graaf 5050?

My amp has started overheating one of the output valves & I am keen on understanding what may be happenning & what components I may need to replace.
Any sage words of wisdom or possibly a set circuit schematics would be gratefully recieved.
