| Options for ridding records of static electricity @suneone,If you read the MSDS for Hepastat 256 - its an alkaline cleaner with non-ionic surfactant and cationic surfactant - the quat, and ethanol (alcohol) and other ingredients. Why add Triton X100 non-ionic detergent? Why add alcohol - what a... | |
| Options for ridding records of static electricity @mijostyn,Audio Magazine 1978-May, starting ~page 44 of 124 has a discussion with measured data for static charge on records. The article does say - "Incidentally, measurements with these instruments have shown that electrification from the dire... | |
| A pragmatic view of cartridge expenses / many questions @audioquest4life,Regarding the Soundsmith Hyperion I heard it at the Capital Audio Show 2018 in the VPI suite. They had two HW40 turntables setup - one with the Soundsmith Hyperion the other with the Lyra Etna. They were playing a Louis Armstron... | |
| A pragmatic view of cartridge expenses / many questions @audioquest4life,Responding to your OP, I do approach with life cycle cost in-mind. I have two tonearms a VPI 10.5i with Soundsmith Carmen and a VPI 12-3D with Soundsmith Paua. I setup the Soundsmith Carmen based on life cycle cost (got a great ... | |
| Options for ridding records of static electricity Just a quick follow-up to my post about 80% H20/20%IPA being capable of removing static charge from an insulator. The reason this works and plain water does not has to do with 'wetting' - the difference between the fluid surface tension and the c... | |
| Options for ridding records of static electricity This post spurred me to do some further research and I came upon this paper that shows that a water:IPA solution up to 80% H20/20%IPA is capable of removing static charge from an insulator (teflon was tested). https://pdfs.semanticscholar.org/c... | |
| Options for ridding records of static electricity @mijostyn,I have had good experience with controlling static buildup during play by grounding the platter bearing of my VPI 2" aluminum platter. This will minimize charging the record bottom during play. My records are all first wet-cleaned and st... | |
| Options for ridding records of static electricity Triboelectric Effect (source MIL-HDBK-263B): “The generation of static electricity caused by contacting or rubbing two substances is called the triboelectric effect. A triboelectric series is a list of substances in an order of positive to negativ... | |
| Tone arm resonance and cartridge compliance: How do they interact?? If curious, this paper on Tonearm Mechanics does a pretty good derivation of the resonance and the effects of mass. http://www.cartchunk.org/audiotopics/ToneArmMechanics.pdf | |
| Thumbs up for ultrasonic record cleaning @terry9, @slaw Something new to try with the Kinetronics Tiger Cloth if using to wipe down a record prior to play - ever so slightly dampen the cloth with an ultra-fine atomized mist of demineralized/distilled water. I am using Nasacort (one spra... | |
| Thumbs up for ultrasonic record cleaning @slaw, You must be out of the USA, otherwise the Kinetronics Tiger Cloth is about $12 with shipping; https://www.amazon.com/Kinetronics-Anti-Static-Microfiber-Cloth-10x18-Inch/dp/B00009R7VT | |
| Thumbs up for ultrasonic record cleaning @slaw,You should be able to wash it without losing the anti-static properties. The anti-static property is provided by copper-infused threads that are woven into the fabric. Anti-static clothing worn by clean-room workers will have carbon thread... | |
| Thumbs up for ultrasonic record cleaning @terry9 ,I cut a piece from the main cloth about 4" x 6". Otherwise, if curious the paper/manual I addressed previously is now published and you can download here: https://thevinylpress.com/precision-aqueous-cleaning-of-vinyl-records/. | |
| Lower end Soundsmith cartridges vs others in same price range? @mijostyn,The effective mass of the cantilever can not be considered in the same way you would apply effective mass to a simple free-pivot tonearm, and the discussion in this article http://pspatialaudio.com/analogy.htm#cantilever, highlights th... | |
| Lower end Soundsmith cartridges vs others in same price range? @mijostyn,If you take the time to wade through this relatively recent article, "Vibration analysis of stylus instrument for random surface measurement" http://wrap.warwick.ac.uk/5705/1/WRAP_Liu_vibration_analysis_2010final.pdf, you may conclud... |
