Question about Audio & Video Receivers
Blown fuse stopped everything working. after strip down , found snapped belt had wrapped around motor on cassette drive causing jam and fuse to blow. replaced fuse,now require new belt and diagram of how to replace it. (sentimental value for my mother , otherwise i would purchase new.)
When a fuse blows it indicates that too much current is flowing. This melts the wire in the fuse.
What is actually damaged is hard to say, remove all the cables and test. If the fuse still blows take the unit in for service.
I doubt that a resistor has died, more likely something has created a direct short. It could be a power supply issue, or an issue with the amplifiers.
Ask for a quote first if it is out of Warranty.

You are literally playing with fire. Obviously the unit is in dire need of service! Please, take unit in for check out by a pro/tech

I am guessing that the ceramic resistor is close to the output transistors. I would also guess that one or more of the output transistors has shorted. This causes a high current draw that is blowing the fuse. You could also have a power supply problem. The ceramic resistor is a .22ohm dual emitter resistor that is used in the output stage. The transistors located close by are probably shorted and should be replaced. Start there and let us know what happens once the transistors and the resistor are changed.
