Unfortunately downloading your hum file doesn’t work on my iPad. I get a file, but cannot listen to it.

If you able to, rename the extension to mp3..
I couldn't export to mp4, and couldn't upload a mp3. I simply renamed the extension to mp4, and at least on windows it played.

Just saw ffmpg can export to mp4.. i must have an old version installed. Will update it and re upload
Name this tune2
Managed to get a MP4 out of audacity...
My guess is its the tube rectifier.... When the house is quiet tomorrow, I will get a much better clip if this isnt good enough....

Ok, straight from my android..
House finally quiet, Besides the hum I can also hear a tinsel sound like a loose filament in a light bulb ... unfortunately the phone mic not able to pick it up...
Never had a SE or tube rectifier, so have no idea if this is normal...
Hopefully this one works for you and thanks for sticking with it....

At least I can hear it now. It’s a very faint noise and it looks like 100 Hz. to me. When tubes are heating they can make some clicking noise, as the interior is heating up (a lot). This is normal.
With regard to the residual humming you will have to check the heaters (AC/DC), power supply, cabling, grounding, shielding, etc.. This may be a tough job, but rewarding in the end. Get your AC voltmeter, oscilloscope and perhaps an audio spectrum analyzer ready!
