First i think it'd be a good idea to see perzackly what's connected between the center tap of the power xfmr and ground. Some of those filters' negative sides are insulated from ground and are connected to the CT. Just for the heck of it, take a resistance reading from that CT to ground. How much resistance does it show? If by chance it's inadvertantly shorted to ground, there would be some hairy ripple and hum bar effects.
In that pic of the power supply area that you posted earlier, it doesn't show where the center tap goes to (kinda fades into the twilight zone). Is it possible you could post a pic showing more of that area?
