Tonearm for Technics SP-15


I have a Technics SP-15 turntable with a Grace 707 arm and a Grace F9E cartridge with a Soundsmith new stylus.  This combination sounds great but is limiting.  The 707  tonearm has a fixed headshell and it does not allow me to easily swap other MM  high compliance catridges or match compliance requirments MC cartridges.  Suggestions welcome from those more expert than I.

Does anyone know if the gst-1 will fit on the SP15?

spindle to pivot ____mm ?

pivot to back of counterweight?

height of gimbal from top of arm wand?

height: to get ’up’ high enough for the SP15 platter height, is a spacer below the arm needed, or the arm post long enough?

will the Victor 7082 fit SP15?

Of course. You can use any arm because the SP-15 is designed without its own plinth, like the SP-10.

ralph,

my friend has a unit in a plinth with a dust-cover. it looks like OEM Technics to me, I could check. Grace arm is in a circular removable board, also looks OEM, with a long oval cutout for various lengths.

removable arm board looks like this

(seller says fits 9 or 12 sme arms

 

the platter has a wide rim, so I am not sure how short an arm will fit. chakster said 10.5" or 12".

 

so it’s not too short or not too long and the fastening from below has to work with the structure of the plinth.

I therefore don’t know if the 7045 is too short, and I was hoping someone knew, if the 7082’s 282mm (11-1/8") spindle to pivot, and the diameter of the arms base plate are long enough/small enough to not hit the rectangular platter housing.

next to last lousy photo here shows the underside, we would need to verify what my friend has

thanks, Elliott
