Unpacking and set - up Take the record player and all accessories out of the carton. Remove the two transportation locks (Fig. 1 a/b) by applying lateral pressure. The locks are located underneath the platter at the front left and at the rear right. Place the belt around the sub platter and afterwards around the motor pulley left of the tonearm rest. Then put the black platter guide on the axis and afterwards the glass platter on the sub platter. It will be automatically centered by the platter guide (Fig.
Electrical connections By choosing the appropriate THORENS mains transformer this record player can be operated from nearly all existing public mains supplies. The low voltage plug on the cable that is coming from the mains transformer unit is to be inserted into jack 17 (Fig. 4) at the rear side of the record player. The stereo signal leads have two phono plugs which are also known as „Cinch“ or RCA-plugs. They are marked with either the letter „L“ for the left channel or „R“ for the right channel.
Adjusting tone arm and pick-up cartridge Turn the tracking force adjuster (1) to „0“ and the anti-skating knob (2) counter-clockwise until it stops (Fig. 6). Screw the tonearm counter weight (3) onto the rear tonearm tube (Fig. 5). Unlock the tone arm (4) and move it a bit towards the centre of the platter. Bring the lift-lever (5) into position DOWN while holding back the tone arm (Fig. 6).
Mounting or exchanging a pick-up cartridge Instead of the factory-supplied pick-up cartridge any other cartridge with standard half-inch mounting holes and a weight between 3 and 10 grams can be installed. Please contact your Thorens dealer if you want to change cartridge. He will recommend a compatible cartridge and adjust it correctly. Replacing the stylus Any stylus is subject to wear even under normal playing conditions.
Operation of TD 148 A Selecting Speed With the knob on the left the speed can be set at 33, 45 und 78rpm (Fig. 7) Selecting record diameter With the button (6) on the right near the tone arm, the diameter of the records can be pre-set, whereby 17 cm is used for „Single“ and 30 cm for „Long Play (LP)“ vinyl records. This function is necessary only when the record player is operated in its automatic mode. (Fig. 8) Fig.
Manual start and tone arm lift Bring the lift-lever (5) into position UP. Unlock the tone arm from its rest and move it above the lead-in groove of the record. The motor and platter will now start turning. By lowering the lift-lever (5) the tone arm gently declines, thus being very kind to your precious records. With the help of the lift-lever the tone arm may be moved up and down again anywhere across the record while the platter keeps turning (Fig.
