| SUT - electrical theory and practical experience @rauliruegas, For the record and no pun intended, TI did not exclude wide bandwidth MM. Their written statement was "This is generally not a problem with moving magnet cartridges, since they are usually severely band-limited above 20 kHz...". O... | |
| SUT - electrical theory and practical experience Not proclaiming to be any expert, but when discussing 'rise time' the traditional engineering parameter s 'slew-rate' dvt/dt = X-volts/micro-sec. And once you are talking about slew-rate there is some pretty established science associated with it... | |
| Will this stuff ruin my records? FWIW - this is what is in Dawn - CPID (whatsinproducts.com). There are 20 ingredients of which only 4 are doing any cleaning - and they are anionic and nonionic surfactants and alcohol. The product is not naturally thick - other ingredients includ... | |
| Will this stuff ruin my records? @rvpiano, You may wish to reconsider - Dirt accumulating on stylus after record cleaning | Steve Hoffman Music Forums - see post #20. | |
| SUT - electrical theory and practical experience Dave Slagle is well a known and respected manufacture of custom SUTs and does an excellent description of the theory and details - intact audio. Beyond that he winds with both copper and silver, and each will have a different perspective to the m... | |
| Ultrasonic record cleaners @drbond Cloud point is not unique to Triton X (100 or 114), it's a property of nonionic surfactants, the book: VIII.2.4.c Nonionic surfactants for the most part do not ionize in aqueous solutions so that the hydrophilic head has a neutral charg... | |
| Ultrasonic record cleaners @drbond Kodak Photo Flow 200 is the wrong fluid to be used in a heated UT - read the book VIII.7; KODAK™ PHOTO-FLO 200: excerpt: " If the surfactant is Dow™ Triton™ X-114, the surface tension will be about 31 dynes/cm, the CMC will be 120 ppm, b... | |
| Ultrasonic record cleaners @drbond The spacing is fine. BUT you have a 6L tank. From a previous post you stated: "4. I slowed the rotation of the motor to about 3 cycles per minute (this is using a low voltage adjustable DC adapter set at its lowest 3V), which is as sl... | |
| Ground voltage!! The 80VAC may be a bit low - How to Test for Ground | DoItYourself.com; Diagnosing Power Problems at the Receptacle | Fluke. Ground to hot should read near same as hot to neutral while ground to neutral should read <2VAC (mine read ~9mVAC) | |
| Ultrasonic record cleaners @pindac, Thank-you for the compliments. FYI - someone did a comparison of the PACVR Manual Method, and results are summarized here: Do I need to clean my LP's? | Page 2 | Audio Science Review (ASR) Forum in Post #31. However, one better th... | |
| Ultrasonic record cleaners Bill (@whart) Tim was first using a no-rinse formula of ~2.5%i-IPA and ILFOTOL and filtered. ILFOTOL is not bad, but it does foam a lot and the delivered concentration can vary, and they did reformulate making what exactly you are working with t... | |
| Ultrasonic record cleaners For those that may be interested, here is a procedure that was developed for the Humminguru: -Buy Tergitol 15-S-9 Tergitol 15-S-3 and 15-S-9 Surfactant | TALAS (talasonline.com) -Buy this dropper bottle - Amazon.com: Nalgene Plastic Drop Bottle ... | |
| Ultrasonic record cleaners @drbond, Thank-you for the compliment. Regarding which kHz is better for LP cleaning; ideally you want both 37-48kHz for preclean and then 80-120kHz for final clean since each frequency targets different type detritus as illustrated in the book ... | |
| Ultrasonic record cleaners @drbond, If you were to download the book the answers would be in Chapter VIII, IX and XIV but I suspect you did not download the book. So, accommodating this: 1. First - Dawn may be a great dish detergent and safe for your hands and cleaning ... | |
| Ultrasonic record cleaners FWIW, One of keys to successful use of UT is bath management - how long is the bath good for use? There are a number of variables. Detritus being removed from a record are either insoluble (i.e. particles) or soluble such as mineral salts and pr... |
