Can hear TV or Radio station via Phono stage ???

It's close to impossible to eliminate because you are using tubes. A solid-state unit would be quiet--and wouldn't sound as good.
Use the mute button on your preamp and try to reorient the phono stage to get the hum to an acceptable level. Move around cables--always with mute on preamp. Otherwise, you can get a big pop that will shut down your amp.
