Can you hear a distinct "crackle" of the high voltage coming up when you turn the set on?

As I try to find a few minutes here and there to do some testing on the set, today I managed to turn it on and listen out back for this distinct "crackle" of HV. What I did hear, and hadn't noticed before, was a consistent buzzing coming from the HV area, as best as I could ascertain by listening. The buzzing came up quickly after turning on the set. It can be heard from the back but not from the front. Should I try to pinpoint the source more closely and how can I do that with some tool (insulated auto stethescope/probe would be nice, right?!). I'm afraid if I put my ear too far in it may come back out slightly toasted. Is anyone familiar with this sound and whether it is normal or tells us anything about the issue. Thanks.
