Need to establish the secondary windings configuration of the mains transformer, ie: are the two windings electrically separate, connected in parallel or connected in series.

Also need to establish the filter configuration for the output of the rectifier, ie: is it CL or LC, if it's the former then I can't see that the choke is doing anything unless there's another large capacitor hidden away somewhere to make it CLC.
