Graham Slee Era Gold Mk IV (2003) build w/ PSU1 power supply

NOTE: Will be out of country starting Tuesday 1-9 and won't return till late Sunday 1-14. Any purchase will not be shipping until after I arrive back in country; post 1-14. 
This is a 2003 GSP Audio  eragold MK IV phono pre-amp. In speaking with GSP they told me based on the serial number, "The only difference between this model and the later one was the circuit board was changed to fit the new case and take a PCB mounted RCA phono socket block, as still used today. The actual circuit itself is exactly the same. We have changed the design very slightly on the current model but it is still essentially the same." It looks pristine and plays absolutely musically as it should. Believe it or not it sounds ever so slightly better than my Graham Slee Reflex series M.  It is in excellent condition with upgraded power supply.  https://www.stereophile.com/phonopreamps/105graham/index.html
