Hello, can someone help me with repairing old yamaha?🤔 I would like to repair this amplifier to learn a Little about electronics but i dont know how to start. When i buy it it has broken transistor 2SC1815 and smoked resistor 1.5k ohm and i replace them and try to power on through lamp and it started then i pluged fuse and the resistor started to burn. I discontcted power source from the main board and measured the voltage on the 2 big capacitors and it was + and - 58,6v
Can someone help me what i need to check more to find what coused burning of the resistor.
I am adding the schematic and the picture where the parts was damaged.
