@dogberry Thanks for the detailed explanation. The Jubilee I am about to get has indeed been sent to John Wright for a rebuilt.
I use a Trans-Fi Terminator tonearm and the builder used to run a Reference. I always understand it to be a good fit. And in fact there is a dealer in my part of the world. But he only carries the Super Gold, which I had put off buying for a few years.
What is involved in a rebuilt? A re-tip?
