K&K Audio Premium MC phono SUT, uses two Lundahl LL1931 Cardas copper-wound transformers, assembled by Kevin Carter, excellent condition. Easy switching between 8X (e.g. for MC cartridges with output >0.5 or 0.6 mV) or 16X step-up ratio, and easy to vary load impedance (if desired) by plugging in resistors of your choice. I'm 2nd owner. Information available on K&K Audio website:
