Looks like nice stuff at a reasonable price.
I don't see any test voltages on any of the transformers. It'd be nice to know if you could use a bridge instead of full wave/center tap.
Usually on those type of xfmrs you do not see Test Voltages. RMS Test Voltages are usually seen on chokes. I looked at the xfmrs and you could probably use a FWB without any problems. Highest voltage xfmr they have is 900v ct. Almost any amount of insulation should be able to handle 900 volts with 450 volts on the CT.
