Unpacking the

SMARTractor

The SMARTractor set contents the following

parts:

* the SMARTractor - completely assembled and

* (3) black tt-Spindle Adapters, engraved with

diameter identification lines. 7.10 (1 line),

7.15 (2 lines) and 7.20 mm (3 lines).

* (1) long stainless steel Locator Pin with round

Reticule w/ white engraved crosshair guide

* (1) metal frame Glass Magnifier

* (6) small self-adhesive "feet"

* (2) M3 20 mm Distance Bolts

* (1) white plastic envelope to store printed

manual

The (6) small self-adhesive feet are only needed

if the turntable features an convex or concave

platter.

In those rare events (Simon Yorke tt or Goldmund

Studio TT or Goldmund Relief mat) do use

these small feet - 3 at a time - to equalize the

SMARTractor relative to the non-flat platter

surface.

The (2) 20 mm M3 Distance Bolts are used ONLY

when aligning a tonearm with unusual tall

bearing housing. The 2 Distance Bolts will give

the SMARTractor an additional 20 mm of height

for the positioning arm in those instance where

required. (For illustration see page 8).

Selecting the

tangential curve

The SMARTractor offers a total of 5 different

Tangential Curves with which to align a given

cartridge and tonearm combination.

You have the option to align the cartridge using

any of these five tangential curves:

- Baerwald / Loefgren A IEC

- Baerwald / Loefgren A DIN

- Loefgren B IEC

- Loefgren B DIN

- UNI-DIN

The selection of the tangential curve depends on

your personal preference and on your record

collection.

If the majority of your records are rather modern,

with production past 1985, we suggest you align

to either

- Baerwald / Loefgren A IEC or Loefgren B IEC

If your record collection contains a lot of older

records from the beginning of the stereo era to

the early 1980ies we strongly recommend

aligning to

- Baerwald / Loefgren A DIN or UNI-DIN

If your collection features a majority of

records with classical music and / or human

voices I strongly recommend aligning to

- UNI-DIN.
