Got this new a little while ago and upgraded the stylus (the stock one is terrible) and it turns this into a decent sounding and extremely portable turntable that doesnt require an external amp or stereo system but of course you can plug it into one via the RCA outputs. Also has a headphone jack and Bluetooth onboard so it really does everything. I used it once to check the stylus and it was great. Comes with the power supply (not pictured). A nifty little throwback record player that will play singles (45s) and regular sized LP records.

A Professional tracking force gauge designed for vinyl record purists interested in more precise measurement of vertical tracking force (VTF). For accurate VTF measurement, the stylus tip should be at the same vertical position as the record surface - that is, at record level. With Riverstones professional VTF gauge, vertical tracking force is measured approx. 2 mm to 3 mm from the surface of a turntable mat or platter - which is the height of a stylus tip resting on an LP record (LPs have a thickness range of 1.9 mm to 2.9 mm). And, with this VTF gauge, there is no need to remove your platter mat - the gauge arm places the stylus tip at the correct height. Less expensive gauges typically have a stylus-tip measurement distance between 6 and 10 mm - which can lead to errors in measurement. To reduce interaction with magnets in MM and MC cartridges, the VTF gauge is manufactured from durable plastic and the detachable cantilevered extension arm is made from a non-ferromagnetic grade of stainless steel. Two calibration masses (5g and 20g) are included for re-calibration (1-minute procedure). With larger calibration masses (not supplied) the gauge can be re-calibrated for use up to 100 g. A polymer pad on the measuring platform protects the stylus tip and allows accurately centering the stylus on the measuring platform. The LED display (green) is bright and easy to read. A very detailed instruction manual is provided. Overall dimensions: 52 mm (W) x 91 mm (L) x 12.0 mm (H); height dimension is with cover removed. PLEASE NOTE: Although no tools are required, installation of the record-level extension arm requires a bit of technical savvy. A tin storage box is included to protect the VTF gauge when not in use. All Tracking Force Gauges are covered by a full TWO-YEAR WARRANTY. ***Requires one Alkaline AAA battery (sorry, battery NOT included)*** A Professional digital tracking force gauge designed for vinyl record purists interested in precise measurement of vertical tracking force (VTF) at the correct vertical height (height changes the vertical tracking angle VTA of a tonearm). When used with the detachable cantilevered extension arm, the gauge closely approximates the vertical position of the stylus on the surface of a vinyl record when it is playing on a turntable - providing accurate “RECORD-LEVEL” measurements of tracking force. For optimal accuracy, tracking force should be measured at the same vertical position as the record surface. With Riverstones VTF gauges patented design (US Patent D878232), tracking force is measured 2 mm - 3 mm from the surface of a turntable mat - the height of a stylus tip resting on an LP record (LPs have a thickness range of 1.9 - 2.9 mm). With less expensive gauges, the measurement distance is typically 6 mm to 9 mm. Precision strain gauge sensor provides 0.005 g measurement resolution and accurate measurements over the entire calibration range of the VTF gauge. To ensure accurate VTF measurement, our VTF gauges undergo a rigorous multi-point calibration procedure to verify the linearity, repeatability and accuracy of the VTF measurement. We have confidence in our gauges and provide TWO calibration masses (5g and 20g) to verify the readings at any time and also allow for future re-calibration if needed. Manufactured using non-magnetic materials to minimize interactions with MM and MC cartridges. The housing of the VTF gauge is manufactured from a durable plastic. The cantilevered extension arm is made from a non-ferromagnetic grade stainless steel and the locking screw of the extension arm is made from brass. A polymer pad protects the stylus tip and allows stylus centering on the measurement platform. The gauge is designed with two levels of battery protection, including auto turnoff of the display and automatically powering off of the circuit after 60 to 120 seconds of inactivity. A detailed instruction manual (in English) is provided. Includes a tin storage box to protect the VTF gauge when not in use. ***Requires one AAA ALKALINE battery (sorry, battery NOT included)***. Tracking Force Gauges are now covered by a full THREE-YEAR WARRANTY.

This unique system employed a cross-shaped armature which, among other advantages, guaranteed exceptional stereo separation since each channel moves on a separate axis. The job of any pickup cartridge is to transform the records physical profile (groove modulation) into corresponding electrical signals (which are then amplified or enlarged by the amplifier and turned into audible sound waves by the loudspeaker. A cartridge must perform three separate and exacting tasks if it is to do this job successfully. It must function mechanically (the movements of the stylus in the groove); it must function magnetically (using the physical movements to create changes in a magnetic field); and it must function electrically (using the changes in magnetic flux to generate an electrical current). At each stage, one type of energy is transferred into another, quite different, type. And the transfer must be perfect, with no energy lost and none added from extraneous sources. No cartridge will ever reach this ideal unless the Laws of Physics can be repealed. However, by understanding the relationships between the three transfer stages and continually applying refined engineering techniques, B&Os belief was that each stage of cartridge improvement would bring each successive cartridge closer to the ideal. Record wear and the cartridgeIf you take music seriously the value of your record collection is likely to be high. Many of your records are likely to be irreplaceable. You will also know that the signals pressed into your vinyl discs are very fragile indeed. The pickup cartridge can be the discs worse enemy since an ill-suited cartridge can mark a record for life in a single play. While B&O is aware that cartridge specifications are inter-related, their research shows consistently that Effective Tip Mass (ETM) is one of the major factors affecting record wear. ETM is the equivalent of the amount of inertia the groove sees in moving or accelerating the stylus tip. Consequently, the higher the ETM value, the higher the force required for a given constant acceleration. Obviously, more force results in more wear. Three elements contribute to ETM. The stylus tip (diamond) contributes with its entire weight and mass. The armature contributes between 5 - 20% of its weight and mass; the cantilever around 30%. B&O has been able to reduce ETM substantially by refining these elements and building them into an integrated unit. The result is a system which not only reduces damage to the groove walls dramatically, but also provides exceptional performance at all frequencies.
