Shure M75 stylus chart
« on: March 17, 2009, 01:27:06 PM »
This post is for all people that are still using the 1960's/70's Shure classic in their Lenco's and other TT.
All M75 body's are inside the same, there's only difference on the outside. First version was a clip in cartridge, second (type 2) has a plastic housing.
There are light, medium and a heavy tracking versions of both the eliptical and the spherical needle.Hypereliptical has two versions. Mono and 78 rpm only one.
N75 HE T2 (light grey) Hypereliptical (0,75-1,5gr)
N75 E or ED or E T2 (yellow) Eliptical (low 0,75-1,5 gr)
N75 G or G T2 (dark grey) Spherical (low 0,75-1,5 gr)
N75 HE-J (light grey) Hyperelliptical .2 x 1.5 (medium 1,25-2,5 gr)
N75 EJ (light green) Eliptical (medium 1,5-3 gr)
N75 6 or B T2 (beige) Spherical (medium 1,5-3 gr)
N75-3 (dark green) 78rpm Spherical (medium 1,5-3gr)
N75 C (light blue) Spherical (heavy 3-5gr)
N75 EC (Brown) Eliptical (heavy 2-4 gr)
N75-1 (dark blue)Mono ?
Any additions? Please let me know! smiley

According to vinylengine.com the maximum recommended tracking force is 2.0g. From memory I think I tracked mine at 1.75g (in an SME 3009 arm).
Paul, using an M75E in your Linn LVV arm ought to be OK. The calculated low frequency resonance will lay somewhere between 7.3 to 10.5Hz, dependant upon the quoted compliance being static or dynamic. Vinylengine quotes it as being the dynamic value, but doesn't say at what frequency it is measured.
Even so it ought not to be a problem, unless you have a 'bouncy' sprung suspension TT that is subject to footfalls.

The M75 E and ED types were fairly compliant and 1.25g was about right for secure tracking. More than 1.5g may cause excessive force on the suspension and this can deaden the sound too much on the rare occasions I've tried it. I have what could be a Jico 'N91-ED' here and although the sound is lively, clean and with a better diamond than Shure supplied, tracking isn't as good. the 'EJ' types could be used under 2g if the arm was stolid enough (lenco L75 for example).
I did once try a V15 III in an LVV with original shell, but the sound wasn't hugely good. Maybe the system I used at the time preferred the falling response of the Rega R100 (current R100 equivalent is the Sumiko Pearl).
As I remember, the 75 'E' was a bonded diamond chip on a wire or similar former which is mounted in the cantilever. The 'ED' is a naked diamond, albeit not a very fine one if my microscope was telling the truth. The design-donor V15T2 was rather finer and even higher in compliance and mine isn't quite as stable as the 'ED.'
Tear down these walls; Cut the ties that held me
Crying out at the top of my voice; Tell me now if you can hear me
hi barry
thanks very much for your help and findings....ive so much to learn here regarding compliance etc.
at some point i would like to change the arm for something better that will uplift the lenco to another level,but thats a whole nother day can of worms!!
the gl75 im using is rigidly mounted...so no bouncey suspension here to play me up.
many thanks again barry.
i never tried the m55 cart and stylus i had at such low valves.
ive now been playing and adjusting it from 1-1.5gm,at present im running it at 1.35gm and im liking what its selling,ive also turned the anti skate to off and that seems to have created no ill effects either.
thanks for the heads up struth.
regards
paul
