Names of Tonearm parts
Introduction
The RB220 is the latest version of one of Rega’s most
popular tonearms.
The RB220 uses Rega’s custom one piece, aluminium
arm tube, carefully manufactured to optimise
performance and reduce stress on the Rega designed
polymer bearings (patent pending). Each tonearm is
meticulously hand assembled using custom Rega
made tools and torque settings to guarantee optimum
performance. This level of care ensures perfect tracking and maximises the amount of information the
cartridge can extract from the record surface.
The RB220 has pre-set bias making this arm even easier
to set-up than previous models. The Rega designed
bias system will adjust the amount of bias as the
tonearm tracks the record ensuring even tracking and
negating the need for user setting.
This Rega tonearm is a precision crafted
product. To create the low friction levels and meet
minimum mass requirements, many parts of the arm
are delicate and require careful handling. The arm
should always be treated with respect and under no
circumstances should any part be removed or
tampered with. Any attempt to modify or repair this
product, other than by an official Rega retailer listed
on www.rega.co.uk, will invalidate the lifetime
warranty.
Set-up
With the cartridge fitted and aligned using the alignment protractor supplied, screw the balance weight
along its shaft until the stylus is “floating” approximately 1mm clear of the record. The recommended tracking force can now be applied by rotating the balance
weight so that it moves towards the front of the arm. A
half turn (through 180 degrees) generates 1 gram of
tracking pressure ( turning the weight 360 degrees will
apply 2 grams). Use the plastic inserts found on the
weight as a guide.
Set the tracking weight to the upper limit of the
suggested tracking weight provided by your cartridge
manufacturer’s guidelines. As mentioned above, bias
setting is pre-set and does not require adjusting. Your
Rega RB220 tonearm is now ready for use.
If you have any doubts regarding correct setup or
fitment of this arm please contact your official Rega
dealer who will be able to carry out the work for you.
Thank you for purchasing this Rega product and we
wish you many years of musical enjoyment.

Fitting your Tonearm
The RB220 will directly replace any other Rega tonearm
that currently uses the three point mounting without
any modification. If fitting to another manufacturers
product or an older Rega turntable (with the single
point nut fixing), the supplied template should be used
as a guide to ensure correct position and alignment.
With so many variants in turntable models it is important
to contact your turntable manufacturer if in any doubt
before making any holes in plinths or arm boards. Before attempting to fit the RB220 arm to the turntable it is
important to ensure that there is sufficient clearance
beneath the turntable and that the arm does not hit
the lid, top or sides. Having checked that there is sufficient clearance in all directions (including the maximum potential arm movement horizontal and vertical)
the next step is to find the position of the centre of the
arm mounting hole. The easiest way to do this will
probably be to use the arm mounting template
supplied.
Arm mounting template guide
The supplied template is for mounting Rega three point
fixing arms to other manufacturers turntables. N.B A
protractor for cartridge alignment is also printed on the
same template.
1. The template should be kept flat and not bent. The
distance between the centre of the spindle and the
centre of the arm hole is critical and must be 222mm.
This template will help you check your positioning before you attempt fitting and drilling.
3. Position the other end of the template so that the
clearance arc is within the rear and side edges of the
turntable base (and the lid when closed). Also check
that there is at least 250mm clearance from the centre
of the hole to the inside front of the turntable.
4. Use a long pointed probe such as a needle and
push it through the ‘arm hole centre’ on the template.
Keep the needle perpendicular to the template and
mark the position of centre on the turntable.
5. Having marked the centre, check again that if the
arm is placed in this position it will clear the under side
of the turntable and the lid. Also, check that the arm is
in a satisfactory position to ensure easy operation and
that the position is pleasing aesthetically. When you are
certain that the arm hole centre is in its correct position
(exactly 222mm from the record centre), you can drill
the required arm hole.
6. The arm mounting pillar requires a diameter of 25mm
which will provide adequate clearance for accurate
fitting. You can then drill the three screw mounting
holes as illustrated on the template. Make sure the arm
is straight and the holes are correctly aligned before
drilling.
7. With the holes drilled, you are now ready to fit the
arm to the turntable. Ensure that you also follow the
turntable manufacturer’s instructions regarding arm
fitting. Each individual turntable manufacturer may
have different requirements regarding positioning of
the arm signal lead.
