1. center of the stereo image If the voice is slightly to the left of center the cartridge should be turned ever so slightly inwards towards the center spindle The increments may be so slight that the naked eye could not detect any change If the sound gets too soft and the image too hazy the cartridge as a whole should be moved slightly forward Consequently if the sound gets brittle it should be moved slightly back These adjustments should be checked again after the cartridge is broken in Please note that the setting for antiskate will also slightly influence HTA Hence changing the antiskating force amounts to a small adjustment in HTA Now adjust the vertical tracking angle VTA If you determine that after the correct setting of the horizontal tracking angle highs are too dull and bass is too plump and uncontrolled the VTA must be increased You do that by raising the tone arm in the mounting sleeve again in very small increments If the sound becomes glassy you ve raised the arm too much At the correct setting highs sound natural and transparent and bass runs sound bouncy and sonorous To underscore the point again Any adjustments which change the basic geometric setting that was determined by using a template or a Dennesen Soundtracktor should be done with great care and in very small increments Otherwise it is easy to loose track and get further and further away from the desired results The rest on the tone arm lift can be height adj2. Mounting Setup and Operations Instructions for BRINKMANN Tonearm 10 5 Mark a point on the tone arm board at a distance of exactly 243 mm from the center of the turntable spindle Use a compass to lightly draw two circles around this point one with a diameter of 20 mm and another with a diameter of 24 mm Mark three points on the outer circle equidistant to each other at 120 angles as shown Drill out the 20 mm circle using a woodcutting bit Bevel the upper edge of the drilled hole slightly towards the center so that the top plate of the mounting assembly with its rounded seam at the mounting sleeve underneath will fit flush on the tone arm board Next drill out the three marked points on the outer circle for M3 size machine screws Insert the mounting assembly into the 20 mm diameter hole making sure that the setscrew for fixing the tone arm in the mounting sleeve is easily accessible The slotted mounting plate and sleeve act like a clamp when the setscrew is tightened To clamp the sleeve it is necessary that the two M3 mounting screws to the left and right of the slot allow some movement They are therefore supplied with copper washers and must not be fixed too tightly The third mounting screw opposite the slot is tightened without a washer Insert the tone arm into the mounting sleeve With the arm sitting firmly in the tone arm rest align it perpendicular to the front of the turntable As long as the setscrew in the mounting p

4. nd using an adjustment template preferably a Dennesen Geometric Soundtracktor Move the tone arm with the height adjustment screw 10 until it is parallel to the turntable and then align the stylus according to the markings on the template Geopoint The tracking force at the stylus tip should be between 1 8 and 2 g not more or less if possible More about that in the chapter on the counter weight The antiskating adjustment 7 at the tone arm should not be set at this point To adjust azimuth take a strong magnifying glass at least 10X and look at the stylus exactly from the front The triangle of the diamond stylus tip should point straight down If a correction is necessary and the cartridge allows this procedure exercise extreme caution when inserting a piece of 0 8 mm diameter steel wire into the small lateral drill hole in the round rod that presses the transducer onto the rubber damper By turning the rod in minute increments without loosening the tiny set screws at the cartridge you also turn transducer and cantilever and with it the diamond tip To adjust the horizontal tracking angle HTA loosen one of the two mounting screws on top of the head shell enough to turn the cartridge in minute increments inward or outward To check the result you must re tighten the screw every time Check by playing a very familiar tune about one to two centimeters in from the beginning of the LP Most revealing would be a solo voice recorded in the
