blown fuse on fairly new Yamaha HTR 5790 receiver
One of the two main fuses blows instantly as soon as power is applied
to receiver. I checked the main power supply caps 2@10,000uf and they were ok. I also checked the bridge rectifier and it was ok. When I remove the two power leads to the transformer it does not blow fuse. The main windings of the transformer are 1.0 ohm. The output transistors are each about 800 ohms at the speaker terminal (prior to relay). What else to check????? Thanks!! |
