Russian Tube Preamp, No Return, Here I go again

Have you double-checked to be sure you got it right?  If so, then I would take the problem to the seller and ask him to reaffirm his instructions to you regarding tube placement.  After that doesn't lead you to a solution,  you need a good tech. 

That's a shame, after all of the waiting.

All is not lost. Broken can always be fixed.

I returned from my trip, took videos showing hookup and recorded noise. Just sent to seller. Tomorrow is going to be the end of seller's hope that I am doing something wrong.

Noise even with nothing connected, just preamp to amp. Both channels, all input selections, 3 videos recorded noise increasing as preamp volume is raised.

Tube placement is quadruple checked, they sent me a photo with the USA and Russian tube designations clearly shown.
