Oh yeah, there is a big difference between typical AM interference and garbled reception with hum modulation.

This 49-901 no longer has that issue. In fact it doesn't hum at all, thanks to (a) a small, 4 inch speaker with limited frequency response and (b) the oversized electrolytics (33, 33 and 33 uF in place of the original 30, 25 and 20 uF configuration).
