It has several problems, bad transformer...
"Bad" transformer? Completely dead, or a secondary winding fault? I'll have to admit that I've never been in a Yammie transformer, but in several Pioneers (Bando). Even the "bad" ones are repairable. Despite the lack of an indication on the schematic, there may be a thermal fuse embedded in the winding.
