Preamp Deal of the Century

Nothing wrong with the one on the website as I just communicated with him on Friday using it.  

There is a good chance that two shipping labels got mixed up and we may soon know who  belongs to the unit in your possession and they have yours.  Also 12 hour time difference so Mick doesn't usually see US e-mails until much later in the day for us.  Also his US tech is a member here who participates in the other Supratek thread.

If you swapped the tubes from side to side to determine they both have the same size pins and they both wobble in that socket then you can tighten the socket's grip with just a jewelers screwdriver.  Many vids on You Tube of how to do it.  Usually doesn't need to be done for years with a tube swapper but I guess they can be loose out of the box.

Is the 300B socket loose in the chassis or is the tube wobbly in the socket as if the pins are too small? If the later that's a simple adjustment.

I've used my Chardonnay and Cabernet with four different SS amps so far with input sensitivities from .6 volts to 2.4 volts and the adjustable gain feature has allowed me to get a noise free match with all of them.  The amps so far are the PS Audio BHK 250, the Van Alstine SET 400, the Nuforce STA-200 and the Kinki Studio EX-M7.  If you need "specs" then contact Mick and ask him.

I've bought two umbilical cords for the two preamps from Brad and they are a definite upgrade.
