Hi,
Good idea.
Done that, been there! The telescopic repair, I mean.
The MMC is worth a better stylus of course.
I have just repaired a DL103 with broken cantilever (keeping the original broken cantilever). I used a tiny medical needle, and believe it or not, the cartridge sings perfectly.
The SP series are easy to do because they have a spigot on which you can attach the alu tube, with moderate force. No need for glue.
I think the MMC4000 has the spigot too.
