OK folks, I really need some help. I've deox'd and cleaned the the tube sockets, and reflowed the vast majority of the solder joints.
I actually thought that I had nailed it when I discovered that the metal plate on the preamp chassis seen in this picture was loose and rattling. I had actually installed it incorrectly. I had also foolishly removed the brown sticky stuff from the edges. So I installed it correctly with a bead of hot glue for good measure. It's on solidly now.
But the noise remains. I need your ears. What does this sound like to you? the noise is good and evident starting around second 5 (and continuing after that).
