IV. ADJUSTMENT
1. Positioning turntable and power supply
a. suitable surfaces are:
- if floors are solid, a solid welded table, sand filled or purpose built turntable
table
- if floor are not solid - welded shelf
- if neither of these options are available, avoid placing on heavy bulky furniture
and place on strong but lightweight surface
b. When carrying turntables tilt of up to 15° should not cause any oil spillage. But
due to the weight of turntable we suggest platter and belt be removed. If you lift
up and remove subchassis as well then the silicon oil will be sealed, but not oil in
bearings.
2. Levelling of turntable
a. Ensure that turntable support is horisontal
b. level subchassis according to instructions in assembly no. 8.
3. Fine speed adjustment
The fine adjustment mechanism is controlled by a switch inside the power supply.
The speed is adjusted in small stages according to the position of the switches.
Adjustment is possible in plus minus 0.4 % in 0.05. steps.
You will need a plastic or wooden tootpick or stick ie. not metal.
a. turn power supply upside down.
b. remove front right rubber (ie. on opposite side to speed selector). This gives
access to switch.
c. place strobe disc on turntable and switch to 33 rpm. By observing disc, any speed
deviation can be noted, but be aware of fluctuation in mains frequency.
d. consult table and according to speed error choose correct setting on switch by
pushing from on to off position by toothpick. This is largely a matter of trial and
error.
e. 45 rpm will be automaticly corrected. Turntable is set already in factory for 33
and
45 rpm.
