"where is the lower end of the bridge connected?"Look at the four lines going off to the left. The top one comes from the 'hot' of the IEC inlet and would go to the fuse holder, then to the power switch, and the 'hot' lead of the transformer. The return lead of the transformer would go to the lower end of the bridge. The other end of the bridge returns to the neutral of the IEC inlet. The bridge is just a standard 25A bridge, the voltage rating is not important.
