EMT STX 5/10 Step Up transformer

That would be a cool find! If the price is right. grab it! Like a Lay's potato chip, how can you just have one SUT? I have several on hand, including a rare Mike Sanders Quicksilver. They each have their own sonic "flavor"!

I may have had one--I got an EMT step up transformer that was matched to my EMT JSD5 (6?) cartridge.  Tried to sell the cartridge and transformer together, but finally gave up and sold the transformer separately, everyone wanted it.  It was a great match for that cartridge.. 

How did the SUT Sound?

 

I am curious too,  but the price may be more impressive than its performance.

Anyone able to hear this step-up?
