Question about Audio & Video Receivers
SOURCE: Have a nearly 30-year old
Look for shorted output transistors or possibly shorted rectifier diodes. An immediate fuse blowing up usually means that the power supply is the problem. Keep us posted.

Very poor cooling could cause this to happen althiough it is unlikely unless the transformer was really cheap and not designed for 100% duty. Severe overdriving combined with poor cooling could do it.
Most likely is .....
Internal short in the winding or a short circuit rectifier on the low side, either way the only way to correctly check the fault is with a variac and some test kit.
Hope this helps
