RB3000 precision tonearm
Rega is renowned for the quality of its tonearm bearing
assemblies. In particular the accurate manufacturing of our
bearing housing and bearing spindles.
Technical characteristics such as “roundness” and
“parallelity” (the condition of being parallel) are critical. Over
the past three years Rega has found a new manufacturing
process which improves on all these characteristics resulting
in a micron perfect bearing t.
The RB3000 is the rst Rega arm to benet from these
improvements. The entire tonearm structure is designed
to have the minimum of mechanical joints while using the
stiffest materials in all critical areas.
Cartridge mounting and seing up the RB3000 tonearm
Firstly, ensure the cartridge xings are orientated correctly
according to the cartridge makers specication. Use the
cartridge alignment protractor (supplied) to accurately set
the position of the cartridge.
Note: When using any Rega cartridge featuring a threepoint mounting system, overhang is automatically set.
With the cartridge correctly mounted and with the stylus
guard removed, ensure that the tracking force dial (a) and
bias adjustment (b) are set to zero. Adjust the balance weight
(c) until the arm is “oating” with the stylus approximately
1mm clear of the record. Note: It is normal for the arm to
swing back towards the arm clip position even with the bias
set at zero. Therefore it is advisable to gently hold the arm
bearing carrier (just below the tracking dial) thus preventing
horizontal movement during the balancing procedure.
Once the arm is balanced, rotate the tracking force
adjustment dial to the required tracking force. Numbers ‘0’ to
‘3’ are marked on the dial. If in doubt, it is advisable to use a
tracking force that corresponds with the upper limits of the
cartridge manufacturer’s range.
Set the bias adjustment slider to the same gure as the
cartridge tracking force pressure quoted by your cartridge
manufacturer. Note: This is not critical and a gure between
1.0 & 1.5 will normally be suitable for moving magnet
cartridges and 1.5 & 2.0 for most moving coil cartridges.
0 1 2
Simply push the bias adjustment slider in to the required
setting, using the dotted line as your reference (as shown
above).
Your arm is now balanced, setup and ready to use. If you
have any doubts regarding installation or setup, please
contact your ofcial 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 hours of musical enjoyment.

ing your tonearm
The RB3000 will directly replace any other Rega
tonearm that currently uses the 3 point mounting,
without any modication. If tting to another
manufacturers product or an older Rega turntable
(with the single point nut xing), 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 RB3000 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 nd the position of the centre of the
arm mounting hole. The easiest way to do this will be
to use the arm mounting template supplied.
Arm mounting template guide
The supplied template is for mounting Rega three
point xing arms to other manufacturers turntables.
N.B. Protractor for cartridge alignment is also printed
on the same template.
1. The template should be kept at and not bent.
The distance between the centre of the spindle and
the centre of the arm hole is critical and must be
222 mm. This template will help you check your
positioning before you attempt tting and drilling.
2. 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 250 mm clearance from the
centre of the hole to the inside front of the turntable.
3. 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.
4. 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 222 mm from
the record centre), you can drill the required arm
hole.
5. The arm mounting pillar requires a diameter of
25 mm which will provide adequate clearance for
accurate tting. 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 t the
arm to the turntable. Ensure that you also follow the
turntable manufacturer’s instructions regarding arm
tting. Each individual turntable manufacturer may
have different requirements regarding positioning of
the arm signal lead.
