Okay, the results are in...

I practiced for a bit on my bookshelf stereo using an old walkman. It picks it up quite well, and I was able to locate the noise (Kind of like a pulsing hum, for lack of better description) and track it up and down the dial.
(Also found that the bookshelf system makes a LOT of noise.. I could even locate the frequency of the VFT display; it would pulse whenever a new segment lit up or went out.)

However, on the tube set, no luck. (took the shield off the 6BE6 for this test). I tried sweeping the frequencies on both the tube set and the walkman. I picked up some noise, but nothing that changed on adjusting the set dial.
