Apple 2 Plus Power Supply Clicking [HELP]

I have been reading for some time now about why this happens. I have found no resistors that could be suspect. I have replaced the capacitor with the one they have suggested. When I power it on without any load it makes a chirping noise. IS there a way to fix this? I can send Pictures if needed. I found the old apple and wanted to fix it but the powersupply went boom and smoked when I tried to power it up. I replaced the RIFA cap that exploded. I ahve a AA11040B model powersupply. I attempted to measure the power supply voltages but they were way off! I found a thread similar to this one but it didnt help. Thanks in advance!

If it chirps when you turn it

If it chirps when you turn it on it could be the 220 uF capacitor.

It's the small one that's sitting by itself about 1/3 of the way from the high voltage side.

 

Have you got any voltage at all on any of the four outputs?
