Default Cayin A-300B schematic needed

I found a Cayin A-300B on the street on top of a refrigerator.
One tube was broken.
At home I found out that the power transformer is not working 220V goes in but nothing goes out.the transformer looks fine.
So the plan is to replace the powertransformer, but it would be best to start with a schematic, so anybody have one ?

Hi Hironimo,
I know it's been awhile but did you find schematics for your cayin 300b by any chance?
Would really appreciate if you could share if you have.
