Has someone got half a minute to assess the hum on this set before I put the chassis back into the cabinet hopefully for the last time.
The hum comes on as the set warms up and is only slightly increased with the volume control. It isn't especially noticeable when the audio is on. The only thing I've done to address the issue is to switch the 6A7, but with no change. Here's link to a 30-second video clip.

My question is whether it's worthwhile to try to kill the hum, or should I leave well-enough alone?
