Fitting your Tonearm
The
RB808
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
RB808
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 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.
