Tonearm TP 250
Adjusting the tonearm lift: this has already been ad-
justed in the factory and can be considered suitable for
nearly all pickups in the market. However if the lift needs
to be re-adjusted to fit a very special cartridge, please do
not hesitate to ask your Thorens dealer for help.
Anti-skating force (bias): this is adjusted by shifting the
button on the tonearm‘s lift bench (2). It is recommended
to set the anti-skating force slight below the value of the
tracking force.
Adjustment of tracking force: make sure to inquire the
recommended tracking force for your pickup from either
the cartridge manufacturer or by consulting the mount-
ing instructions supplied with the pickup. Tracking force is
usually adjusted between 10 and 25 mN (corresponding
to 1.0 and 2.5 grams). First lower the lift lever and move
the tonearm to a position in between its rest and the outer
rim of the platter.
Then balance the tonearm by rotating the counterweight
(clockwise or counter-clockwise) until equilibrium has been
achieved. HINT: anti-skating force (bias) must in any case
be set to “0”. Now you can apply tracking force by rotating
the counterweight (3) according to the following scheme:
a half turn of the counterweight corresponds to a track-
ing force of 10 mN (1.0 g) whereas a full turn corresponds
to a force of 20 mN (2.0 g).
Turning the counter-weight towards the bearings will in-
crease tracking force, whilst turning it into the opposite
direction will decrease tracking force. The green dot on
the counter-weight is to measure the turns.
Make sure the tonearm is kept in its armrest be-
fore making these adjustments.
