The Zener idea seems more mysterious the longer I look at it. Since I am not quite sure where you have connections in your schematic and where the lines are just crossing without any connection I may be wrong, but:
- If we mentally remove the transformer center tap and everything connected to it, you have a standard bridge rectifier setup, only with serially connected smoothing capacitors. I can live with that.
- Now to the center tap. The way it is connected, it will have a DC potential at the half of B+, including the ripple.And it looks like you try to connect it to half the Z potential though a 100V AC drop...
- The standby switch. When that switch is open, you still have an AC path through the lower half of the transformer. Exactly what happens to B+ is a little unclear, but it will be at least 240V.
