THORENS TD 309 - Manual (Page 27)

The suspension in each sub-chassis foot can be
adjusted from above with the help of a 5-mm hex key
(
➔ Abb. 6 ). The inner cylinder of each foot should pro-
trude by 2 mm at position X.

The suspension system is factory-adjusted. It should
be readjusted if the weight of the turntable is altered
(e.g. through the use of stabilisers or heavy platter
mats) or if the supporting surface is not perfectly lev-
el.
The platter speed can be adjusted by turning the ad-
justment screw to the left or right of the speed switch
(for 33 ⅓ and 45 rpm, respectively).
➔ Fig. 7
The platter speeds are factory-adjusted. Any readjust-
ment of the speeds should be checked with the help
of a test record or a strobe disc.
