DENSEN DM-10 need schematics

I cannot find a schematic but unless its got a complicated power supply stabilization and cut-out circuit built in a power supply can be easily checked .


Disconnect the output from it to the amplifier --test for a very low resistance on the feed to the amplifier --if not then the fault lies in the power supply components -- a step at a time --slowly.


I do know it has two transformers .
