PHONOGRAPH CARTRIDGE & STYLUS x CARTRIDGE (PHONOGRAPH) x NEEDLE (PHONOGRAPH) x STYLUS (PHONOGRAPH) xx PHONOGRAPH xx PHONOGRAPH TONEARM Audio fundamentals. The matching myth. Part 2. Optimum loading and magnetic phono cartridges. Audio fundamentals. Equalization for phono replay. Observations on the effects of ambient temperature on magnetic phono cartridges. Grounding a Philips 412 phono cartridge so that it doesn't snap and pop or collect a lot of dust on the stylus. Tip on quieting static snaps when using the Shure Type III cartridge. Transient response (a do-it-yourself clinic). Practical solutions for your system to make recorded music sound more like live music. Looks at cartridge, preamp, amplifier, speakers, etc. Component interfaces. Part 1. Phono cartridge interface with the preamp. Selectable phono input capacitance. An outboard device to vary the capacitance when matching cartridges to tone arms and preamp input sections. Simple technique for setting up a stereo pickup cartridge's vertical azimuth. De-ringing transformers in your audio system. A simple way to make moving coil transformers behave. A pre-preamp for moving coil cartridges boosts their low output voltage before being connected to the preamplifier. Improve the sound of the Sonus Blue or Red cartridges by judicious application of "Mortite". A moving coil step-up transformer for use with a low output moving coil phono cartridge. The gain is switch selectable and the input and output circuits can either be isolated or connected together as an auto-transformer. Who has the perfect tip? An essay on research into the factors involved in the stylus-to-groove relationship and development of a new shape for stylus tips. Alignment of a line contact (LC) stylus is made easier with a simple cardboard gauge. Tips to improve the operation of Grace F-9 series moving-coil cartridges. Old wheels and the RIAA. Circuit for a precision RIAA/EIC tester based on the mathematics of Stanley Lipshitz is used to test phono cartridges. Moving-coil phono cartridge transformers. Make your own step-up transformers to adapt a "normal" phono input to the low input of a moving-coil cartridge. The LP terminator. Presenting the theoretical background and method to properly terminate a magnetic phonograph cartridge. Tips on choosing the right phono cartridge. Let's look at cartridges. Convert stereo record player from ceramic to magnetic cartridge. Crystal cartridge checker measures pickup output voltage and doubles as a signal tracer. Est. cost: $14. How to pick a phono cartridge. Interpreting manufacturers' specifications. Electronic device logs the number of hours that a hi-fi phonograph stylus has been used. The number of hours is displayed at the touch of a button. Estimated cost: $50. When and how to replace phono needles. How to select a phonograph cartridge. Electronic stylus timer that monitors the output of a cartridge. Includes instructions on assembly and calibration as well as a chart so you can find the Rx for your cartridge. Easy way to test your own phono cartridges using test records and an oscilloscope. What you need to know about the modern phono cartridge, plus how you can measure the frequency response of your cartridge, determine the proper load impedance, and maximize performance. Take advantage of the new solid-state stereo phono cartridge that needs no preamp and offers low distortion by building this simple power supply to match one to your amplifier. Est. cost: $4. Tips on discovering and replacing a defective stylus. | |||||||||
