| TONEARM DAMPING : DAMPED OR NOT ? ? USELESS ? ? WELCOMED ? ? @rauliruegas,I have both the VPI 10.5i/AL-tube (EL = 266mm) and the 12-3D /printed-tube (EL-313mm). By just a simple balance analysis, the 12-3D tonearm fwd of the pivot is 3X the weight (not effective mass) of the 10.5i tonearm fwd of its pivot. ... | |
| Stylus stuck in groove @rvpiano,Being a bit a more pragmatic - a UV light can sometimes indicate debris that you will not be able to see with ’white’ light. and assist those aging eyes. This unit has good power for the inspection - only expose the record to the UV light... | |
| TONEARM DAMPING : DAMPED OR NOT ? ? USELESS ? ? WELCOMED ? ? Dear @rauliruegas,FWIW - when I tried the Technics 3mm rubber plater mat, I stayed with it for a few months - I know it can take that long before I get over the newness factor and declare it good or otherwise. But, here is what happened - after a ... | |
| TONEARM DAMPING : DAMPED OR NOT ? ? USELESS ? ? WELCOMED ? ? Dear @rauliruegas,Thank-you for the forum references. My choice of the word lifeless was more in haste then any proper assessment. I found the softer rubber Technics mat to put a soft-focus on the music; the small intricate details were missing;... | |
| TONEARM DAMPING : DAMPED OR NOT ? ? USELESS ? ? WELCOMED ? ? Here is another cartridge article from from the past (B&O cartridge designer) https://worldradiohistory.com/Archive-All-Audio/Archive-Audio/70s/Audio-1979-03.pdf.A couple of items to grasp is the amount of pressure (1000's of psi) that the st... | |
| TONEARM DAMPING : DAMPED OR NOT ? ? USELESS ? ? WELCOMED ? ? @rauliruegas,You and @lewm have it right - every application is different. Its more than the just the cartridge and its compliance. There is a decent article on tonearms in this Audio Magazine https://worldradiohistory.com/Archive-All-Audio/Arch... | |
| Record Care Regime can I do better ? @swann36,To repeat a post I made over at Steve Hoffman (with a few mods) and in reference to your issue with the stylus collecting gunk: This review of the Disco unit Disco-Antistat Vinyl Cleaning Machine From Knosti - The Audiophile Man , states ... | |
| Record Care Regime can I do better ? @mijostyn;Most chlorofluorocarbon solvents stopped manufacture in 1996 per the Montreal Protocol. CRC brake cleaning fluid https://www.crcindustries.com/products/crc/crc-brakleen.html now come in various compositions, one non-flammable version... | |
| Glue from inner sleeves leeching onto records mijostyn, rich121,Be careful with CRC Brakleen - it contains mostly Tetrachloroethylene (Perchloroethylene) which is a chlorinated hydrocarbon (most CFCs solvents stopped manufacture 1996). If you use CRC Brakleen read the MSDS carefully - ht... | |
| Options for ridding records of static electricity @mijostyn,This was likely the last (and best?) patent that RCA filed for vinyl record composition - https://patents.google.com/patent/US3960790A/en, this is the patent download - https://patentimages.storage.googleapis.com/b6/ac/a3/33b9d37bfdc952/... | |
| Options for ridding records of static electricity @uberwaltz,If its consistent with particular records then it can be the vinyl formulation, and RCA made note of this in this magazine - https://worldradiohistory.com/ARCHIVE-RCA/RCA-Engineer/1960-10-11.pdf - read the article about anti-static r... | |
| Options for ridding records of static electricity @orthomead,(I am reposting since I accidently addressed this to wrong person. I deleted my prior post.)To follow on what @mijostyn said, MIL-HDBK-263B does state - "Some metals, can create significant charges from triboelectric generation. Aluminu... | |
| Options for ridding records of static electricity @mijostyn,The root cause gets complicated because the following are some of the known (and unknown) variables:1. Humidity. Redo your experiment this winter with humidity ~35%, and I suspect you will see a difference; not only from the environment... | |
| Options for ridding records of static electricity @mijostyn, Know for sure I am not laughing. But, I have a lot of respect for you! It takes a rationale and courageous person to face their own preconceived notions unbiased - its also show discipline, My compliments! Stay safe, Neil | |
| Options for ridding records of static electricity @mijostyn,"I would like to get this settled once and for all" My only response is good luck. There are so many variables. The ambient humidity; the various ground potentials, the record material (which is a complete wildcard), the record mat, t... |
