It’s not like there is a magical wardrobe filled with them out there……
Well, not filled, exactly.

4.5, I think.
The CW broke part of the plastic damping outer chamber where the cage inserts. I made it worse when I tried to swap one in from a spare parts unit. I need to harden a spring and fabricate a bellows to fix it. It’s pretty low on a very long list.
Now I know who to pester if I get a hankerin' for an EPA arm...4.5, I think.
I’d want to get something like my kenwood optical cartridge going first, and I don’t even remember where that is.
I measured tonearm C yesterday.4.5, I think.
I measured tonearm C yesterday.
Can't vouch for accuracy, Fluke 87 V.
Lowest scale nF
Removed head shell
3' of BJC LC1 reportedly ~40 pF, which alone read ~0.04 nF.
With arm bounced 0.06 - 0.07, dwelled on 0.07 nF. Safe to say <0.08 nF w/o head shell leads? So arm ~ 0.3-0.04 nF, 30-40 pF

DUT?Also note that if I connect a lead at either end of the DUT I go from 43pF to 60pF.
Overhang is 15mm, which should be the standard Technics distance of 52mm from headshell collet to stylus.So I did end up with an armwand for the 250. Can anyone tell me what alignment Technics used on this arm? I really want a tool that can show me the correct OEM way to set it up!

I believe Technics uses a modified Stevenson geometry.
