Fitting your tonearm
The RB880 will directly replace any other Rega
tonearm that currently uses the 3 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 RB880 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 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.
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
222 mm. This template will help you check your
positioning before you attempt fitting 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 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.
