request you not type in caps. It looks like you are yelling.

Very broad, but it sounds like a blown output transistor
(most likely) or power supply problems.

good that the fuse blew instead of speakers/or fire.

The 7300 was made about 20 years ago and was replaced in the early 90's with the 2600. It has 20 years under its belt and its probably time to consider replacing it along with the other six of them. It is probably suffering from several blown outputs as well as damaged drivers and possible power supply damage. This amp is also old enough to consider replacing its power supply caps as well as the other caps. Call a local professional sound contractor and have him assess your system to get it into the 20th century and replace your antique gear.

New thermal grease or silicone insulators
on all outputs/drivers, 100$ in new caps
