In this post from nearly ten years ago, the ARRL Handbook is quoted. Note the specific statement that chokes in the ground line are avoided in radio receivers and audio amplifiers due to excess hum.
If you click on RayP's post (to which Jimmy's is a reply) you will find a more extensive discussion. Especially note Ed Sawyer's post, where he found 1000mV hum with this topology, which was reduced to 2mV when the choke was moved back to the high-voltage side.
