Soulines tt clamp Turntable clamp, hence tt clamp, or record clamp can be a very useful accessory, especially when playing slightly warped records. Instead of adding weight and excessive wear to the main bearing and the turntable drive system, it applies force to the spindle and platter only, clamping the record securely to the platter, thus stabilising the record and providing ‘lifting’ to the performance, tightening frequencies across the spectrum and subduing any resonance that may occur as the needle tracks the groove of an unsecured record. Besides the capabilities of fulfilling its obvious task to secure and stabilise the record, when designing Soulines clamp our intentions were to create an optimal mechanical connection-bonds between the clamp, spindle, record and platter by employing appropriate materials for the task according to their mechanical characteristics, hardness, stiffness, softness, damping properties, etc. Thus, the clamping disk is made of POM (polyacetal), stiff plastic material, with excellent damping characteristics; collet chuck or the clamping sleeve is made from brass which is softer than aluminum, stainless steel and other hard materials usually used for the turntable spindle, allowing a good grip to spindle; locking nut is made of aluminum, stiffer than brass, so ideal for the locking nut tightening task. Depending on the platter/mat design and particular record thickness and warp state, Soulines clamp requires user to place a washer around spindle before placing a record onto the platter and before securing the clamp, thus two pairs of washers of 17mm and 23mm diameters, made from cork and rubber-cork are included, allowing user to experiment and use the right one (or a combination of a two) for the best results.
