Totem Sub Woofer Amp

This arrived recently in the workshop.A power supply electrolytic has blown, taking out the fuse. From a visual inspection that appears to be the sum of the problem. Electrolytic failure is very common in these sub woofer amps. A lot of heat in a small sealed box with low temp rated capacitors is a recipe for relatively frequent failure. Capacitors will be replaced with uprated ones.
