Hum 5e3 New Building

[Blackface5f6]

Hi,
I built new 5e3 and it sounds actually good but the is really funny hum:
- When I turn the Amp there loud hum
- After 43 second there is "dub" (Funny ) and the Hum is louder than before
- After 1 minute 10 second there is "dub" (another funny thing) and the Hum is really loud

I added sound sample to this posting

Tried to watch the video. but it was a pixelated mess in my browser.  I didn't watch it.  Why not tell us about the amp?
Is it a kit or built from scratch?
If you have a schematic document, upload that with your post. 
Take some good clear pictures of the circuit board showing the layout and connections so we can see your work.  Upload those with your post.
Do any of the controls affect the sound, if so how? 
Does it hum with a guitar plugged in?  If so, how does that affect the sound?
