Default Sharp SG-FR35 loud hum

Hello

Can anybody give me some pointers help eliminate a loud hum when switching on this device? I have replaced the 2200uf capacitor in the power supply side as the existing one was bulging and leaking grunge. The hum is very loud across both channels and sounds like a failing smoothing capacitor. Disconnected the transformer is giving out about 28volts.

Your assistance is appreciated.
