Sorry, I had to ask about the inputs - I realize its a trivial thing.
If the DC power cord is connected properly and not mis-aligned, then perhaps there is a real problem.
I wonder if this could have been caused by tubes which are shorted.
Did you by chance remove the 6L6 tubes and play the Supratek to see if that solved the problem?
