While digging in a box of cables belonging to a deceased friend, I found an Entre MC 1 cartridge rattling around, sadly with the diamond inexplicably hanging on to the upper aspect of the cantilever, rather than the usual underside, so likely non functional, but otherwise the cantilever seems intact, and the suspension ok. I'm sure a retip would be £300 at least - is it worth it? I'd be running it on a SME 3009 S2 improved with a removable headshell.
