ADJUSTMENT OF THE SPRING TENSION
The sub-chassis should be evenly aligned and vibrate absolutely
vertically. Neither wobble nor dier in height. To check and correct
this, proceed as follows. 1:
01. push the turntable slightly downwards at the centre axis. This
stimulates the sub-chassis and it should vibrate evenly.
02. Check the height of the tone arm board and the top board.
Both should be exactly the same height, no jump in height
when you run a finger over them.
03. Check the distance between the lower edge of the plate and
the topboard. This distance should be the same around the entire circumference of the plate.
04. If both the height and the vibration behaviour are as described, everything is in order.
05. If, on the other hand, the sub-chassis wobbles and swings or the plate is not parallel to the topboard, the
spring tension must be corrected.
06. Take the rubber mat o the turntable and turn it until you can see the three adjustment screws for the
springs through the large holes. These are located in a triangular arrangement below the platter but can be
reached through the holes in the platter (Fig. 17, Fig. 18).
07. Now adjust the spring tension of the three conical springs with a 2.5mm Allen key that fits into the groove
of the nut visible through the plate. Turning clockwise increases the tension, lowering the sub-chassis at
this point, turning the other way releases the tension, raising the sub-chassis at this point. Always check the
vibration behavior in between.
08. The correct setting is achieved when the sub-chassis moves exactly vertically and the distance between
platter and the top board is the same everywhere.
