I wish you luck. My Reference, recently rebuilt by John, is not going to be sold, and nor is the Jubilee I have as backup. You could probably find a used Super Gold or Maroon more easily if you are willing to go there. There is a very long and informative threat over at Lenco Heaven with many owners participating.
As for set up advice, the modern London pickups are much less fussy than the older Decca designs. I have never heard any hum or had any tracking problems. I have used them with SME Series V and M10 (like the 309) arms.
