Why not just put the coil of a relay in parallel with the transformer
primary. When the filter capacitor charges up enough it will let the primary
voltage come up enough to pull the relay in. If you don't like to hear the
relay coil buzz while the voltage is coming up add a diode in series with the
coil. A series resistor and a capacitor across the coil will adjust the time
delay if you want more. I have used just the relay by itself. Works great.
