Tell us the picture you posted is the "before" version. All those rotted out capacitors must go.

For ultimate protection, drill a hole and mount a fuse holder in back of the chassis, if you have room. Say, if 1 amp is about right, make it so. Nothing stopping you from adding a second fuse under the chassis, say 2 amps. That way if trouble arises and someone gets creative in replacing outboard fuse, you could prevent a total meltdown or fire hazard. This is standard practice in recently manufactured guitar amps.
