| A Few Turntable Measurements using the RPM Android App My concern is that the weight of a cell phone placed eccentrically on the platter will per se skew the reading, especially for wow and flutter. Furthermore, is there independent evidence that the rpm readout is accurate? I thought there was some d... | |
| Step Up Transformer Two different things. I think you’re referring to current driven phono stages that supply all the gain needed plus RIAA correction. There is a plethora of those. I’m talking about a current driven external gain-only device that does not supply RIA... | |
| Step Up Transformer Another new option to consider is to use an outboard current driven gain stage to feed a very good MM stage. Sutherland make one, and I’m using one from another source that was custom built for me. Results are excellent if you’re limiting your cho... | |
| The "Very Best Record Cleaning Formulation" In Europe, the PhD is generally regarded as superior in academic achievement to the training required of clinical physicians. In the UK and maybe in Germany and elsewhere on the continent, clinicians are addressed as “mister”, and only PhD recipie... | |
| You've run some pretty fancy MC's, but the _______ MM cartridge really impressed me gakerty, I love the 980LZS, too. In my case, I have the 981LZS, one NOS and one used. It is said that the 981 is a selected 980, but i doubt that makes any difference. | |
| The "Very Best Record Cleaning Formulation" Dear Wizzzard, of course osmolality does not describe the level of “particles”, and I never said it did. I did say that osmolality is used as a measure of the degree of deionization of water. Then Mijostyn conflated ions with particles, and I corr... | |
| The "Very Best Record Cleaning Formulation" Wizzzard, sorry to say you did misunderstand me, not that it’s any obligation of yours to deal with every idea here. What I am trying to ask is whether there’s any problem with deionized water, if and only if it’s also distilled. I get that you’re... | |
| The "Very Best Record Cleaning Formulation" Mijo, I wrote that deionized water is commonly evaluated for the degree of deionization by measuring its osmalility. Note the root word, “ion”. Ions are in solution by definition. So what has this got to do with particles, which are not in solutio... | |
| Turntable is the most expensive in the chain, do it make sense Interesting sentences from the CS Port website: "Servo noise is eliminated by open control that does not apply a servo. In addition, a highly accurate voltage is supplied to the motor without fluctuation based on a crystal oscillator with high fre... | |
| Step Up Transformer Not sure what you're after. Bobs Devices SUTs are certainly "off the shelf", and if you purchase one of their best SUTs, and one that is suitable to both your cartridge and your phono stage, you will probably have wide bandwidth and low distortion... | |
| The "Very Best Record Cleaning Formulation" Just to say that deionization and distillation are two different processes. You can have one without the other. Hence my question to Wizzzard. (Careful to get those 3 Z's in there.) You (Rich) make a good point regarding store-bought distilled ... | |
| The "Very Best Record Cleaning Formulation" Dear Wizzzard, as regards water, I gather you would approve of water that is both distilled and deionized. I think what you’re trying to convey is the notion that deionization alone is insufficient. Is that correct? Distilled and deionized water ... | |
| The "Very Best Record Cleaning Formulation" Pindac, I was not giving you advice; I was merely trying to point out that the world of nonionic detergents can be confusing because sometimes the different chemical companies use different names for the same molecule. Ergo I thought you might wan... | |
| The "Very Best Record Cleaning Formulation" Pindac, very often identical nonionic detergents are sold under different names, depending upon the manufacturer or patent holders. You might check to determine the chemical relationship between your preferred preparation and either tergitol S7 or... | |
| Step Up Transformer For what it’s worth, and that’s probably not much, a SUT increases signal voltage (not “current “), and a SUT decreases signal current in direct proportion to the increase in voltage. The product of voltage X current at the primary is equal to the... |
