Well it works anyway!
As I write it's currently playing Dusty Springfield.
I might be mistaken but I may not have been fully aware before that 'Little By Little' is actually in stereo
~ not by very much admittedly
Had to jiggle the arm position a bit more to get the actual 222mm between centres. Then I used a Stevenson protactor which I drew (well, modified an existing one) which includes the 15mm overhang marking.
Having got the stylus on the ovehang mark (isn't it useful that the arm rotates enough to go over the centre spindle!), squared it on the inner grid, then lo and behold when moved to the outer grid it lines up. Just like that.
When finished moving the cartridge about, VTF next, used a cheap-n-cheerful balance, but does the job (was calibrated on the TP16 arm). The Nagaoka requires 2 grams, or a shade under. Nip up the counterbalance Allen grub screw, sorted.
Crikey the antiskate is a bit powerful innit?
Shifted it up to 2g (far as it will go), and it's dragging the arm on the rest! '1' seems quite enough. Can't see the cantilever bending one way or the other, and 0.5 (antiskate) not enough (top treble goes off a bit on left channel).
Lastly 330pF mica caps added to phono pre input sockets so's it's running into >500pF.
And that's how you do that...
