Sunfire HRS-12

Working on a Sunfire HRS-12. Bridge rectifier was shorted and fuse blown. I replaced the bridge and recapped the power supply board. Replaced fuse and tested. this is what i get on the output to the speaker. Sorry, can't get the scope to trigger on it. But, you can see the wave form. Can't locate a schematic for it. Any help would be appreciated.
