Due to the inherent precision in the arm's construction, very minute changes of VTF are possible by "Preloading" the VTF adjustment screw prior to loosening/tightening the counterweight if adjusting by ear. Much more solid than the flimsy plywood plastic covered original. This "presets" the anti-skating for optimal calibration. Turned to match the customers original and with SME mounting slot. As a final adjustment before snugging up the two 3mm HTA Base clamp bolts is to (Figure 132, ) laterally position the tonearm rest so the front inside corner of the headshell is distanced at 205mm away from the center of the platter spindle.
These 2 critical small washers simply fit into the recesses on the top of the headshell under the fingerlift. SME is a brand name of an English company that produces high end tonearms and turntables, whose name has become synonymous with the industry standard.

If fingerlift use is desired for manual cueing, be sure to utilize the 2 small bellville washers (supplied) which enable proper decoupling of the fingerlift as shown in the setup manual (Figure 112, ). This HTA adjustment allows for instantaneous alignment without ever changing VTF - a hallmark of the design. Some of the SME protractor templates are provided with an oversized spindle hole for use with a supplied spindle bushing for even more precision and less friction. The key here is precision combined with low friction of the template gliding clockwise/counterclockwise on the record surface with HTA Key manipulation.

If careful, it is VERY possible to drop stylus into protractor target dimple before using HTA Key to gently push/pull template under tonearm outline. With a detachable magnesium head-shell that features an advanced style coupling, the Series 309 tonearm offers the convenience of rapid cartridge interchange. Protractor template may be used on top of a flat record placed directly on platter without use of reflex clamp washer under record.

A simple lateral manipulation of the tonearm rest/support bracket will confirm if the 2 clamp bolts are loose enough to adjust tonearm while still the tonearm is still being supported. Make sure the 2 lateral 3mm clamp bolts in the HTA base are loose enough before making HTA overhang adjustments with the HTA Key inserted.
