Record Cleaning Using Vacuum Machine for Cleaning and Ultrasonic for Final Rinse @richardbrand, If you are spinning 9-records in a 6L tank, there are 2-problems - too much mass in the tank and you are overloading the tank, and even at a slow spin speed you are developing enough fluid flow/motion to pretty much kill most cavit... | |
Record Cleaning Using Vacuum Machine for Cleaning and Ultrasonic for Final Rinse @oberoniaomnia, The density (rho) of Tergitol is not 1, its specific gravity is essentially 1, so it's the same as freshwater which is 62.4-lbs/ft^3, convert to mg/cm^3 = 28,304,164-mg/28,316.85-cm^3 = ~1-g/cm^3 = 28,316,846-mg/ft^3. How did you... | |
Record Cleaning Using Vacuum Machine for Cleaning and Ultrasonic for Final Rinse @richardbrand, Thanks for the compliment, but not exactly a labor of love. I started that project during COVID when I was retired (not anymore), and it kept me occupied and my skill sets sharpened. And thanks to meeting up with Bill Hart @whart... | |
Record Cleaning Using Vacuum Machine for Cleaning and Ultrasonic for Final Rinse @oberoniaomnia, how do you get from mass of pure dehydrated Tergitol to film thickness of 31 nm? Tergitol is something like a C33 hydrocarbon chain and generally hydrocarbon chains are around 1 nm thick (e.g., sugar). I failed to find any infor... | |
Record Cleaning Using Vacuum Machine for Cleaning and Ultrasonic for Final Rinse @billstevenson, Bill, thanks for the clarification. Take care, Neil | |
Record Cleaning Using Vacuum Machine for Cleaning and Ultrasonic for Final Rinse @billstevenson, Bill, I am not sure if you took what I wrote in Chapter XIII out of context. The records are vacuum dried because Neil reported finding 10%-30% residual solids left on the record surface using air drying techniques. So it is im... | |
Source of Fremer's "1 arc second" claim? @pryso, I also consider MF to be a boon to the vinyl revival, not a bad dude. Please do not misunderstand my criticism. MF has been steadfast proponent of the vinyl playback and deserves the recognition and compliments he gets for that. But... | |
Source of Fremer's "1 arc second" claim? @pryso MF reviewed the Oswald K3 Analog Corner #314: OMA K3 turntable & Schröder tonearm Page 2 | Stereophile.com and per this article (last paragraph) confirms that he bought the unit - Oswalds Mill Audio K3 Turntable - The Absolute Sound. | |
Source of Fremer's "1 arc second" claim? The 1-arc-second likely originates from this turntable vendor whitepaper - Oswalds Mill Audio - K3 Whitepaper | OMA of which MF owns (or owned). There are a number of errors in the white paper: "...our device needs to actually physically trace m... | |
Record cleaning formula using Triton X-100 b. 10: Water-soluble (lipid/oil-insoluble) Just to clarify, it should read as follows: b. > or equal to 10: Water-soluble (lipid/oil-insoluble) Sorry for any confusion. Data comes from Hydrophilic-lipophilic balance - Wikipedia | |
Record cleaning formula using Triton X-100 @toddnlg, If you first add alcohol to water and then add the surfactant, the surfactant will not go into solution quickly, it will go through the solution like a stone. If you add 15-S-9 to DIW, it begins dissolving on contact, one of the benefit... | |
Record cleaning formula using Triton X-100 @toddnlg, The 20% IPA and 0.02-0.05% TX100 in distilled water listed by @lewm is a good detergent receipt, but it requires a rinse - it's not a no-rinse formula. One note of caution - the above blend with 20% IPA is intended for small quantit... | |
Record cleaning formula using Triton X-100 @toddnlg, The 20% IPA and 0.02-0.05% TX100 in distilled water listed by @lewm is a good detergent receipt, but it requires a rinse - it's not a no-rinse formula. A key property of nonionic surfactants is critical micelle concentration (CMC). S... | |
Perfect Vinyl Forever @taww, Purchase distilled water from your local grocery store. | |
Perfect Vinyl Forever @taww, Congrats on your return analog, nice rig and enjoy the journey. Many people purchase a 2nd Spin-Clean that contains only distilled/demineralized (DIW) water as a rinse. Using just one Spin-Clean without a rinse, there is risk of leaving ... |
