| How much isopropanol is effective but safe for viny? I found this, from an article written by a chemist:"Unfortunately, there are many misconceptions related to plasticizers – for example, about phthalates “leaching out” and “easily dispersing/gassing out” from PVC products. This is actually unlikel... | |
| How much isopropanol is effective but safe for viny? bpoletti, After a search of the scientific literature to support your claim (which I have heard before this) that alcohol removes plasticizers from LPs and could by that mechanism damage them, I found exactly one reference, which is contained in a... | |
| Turntable So far, Helomech offered the most cogent point. Make sure your turntable does not have sintered bronze bearings, by all means. And then don't use the stuff regardless.Friction in a piston engine, which lives at very high piston velocities and wh... | |
| Grado Labratory Wood Tonearm? 3 questions: Keep it? Sell It? Burn it? I have no first hand experience with the Grado tonearm, but I doubt that it is much more of an antique than the SME 3009. Being "vintage" does not per se mean a tonearm is no good or irrelevant. Tonearm design really has not changed much in many... | |
| Turntable Walker Audio SST silver paste works,too, but that’s a different application. | |
| Turntable Miguel, I think the same cautionary notes apply. In this case, you'd want to know that the sealer does not interact with the actual lubricant in a bad way. Anyway, for a turntable bearing, I would also wonder why sealing the pores in the metal p... | |
| Valve phono stage oholter, you have an advantage on me, because you have owned and aesthetics Io and I have not. However everything I can find on the Internet about it suggests that the phono circuit is balanced, contrary to what you say above. Do you know differen... | |
| Turntable Mr. M, I will answer the question you posed to EBM by referring you to my post just above which mentions that an unknown complex lubricant might contain additives that could be corrosive for the ball bearing or the thrust pad. To know whether that... | |
| Turntable It's another lubricant, no more, no less. Maybe it is superior to other common choices for turntable bearings. Maybe not. I think Miguel raised an interesting question, but none of us is qualified to say yea or nay, since none of us has used it... | |
| Koetsu cartridges - what arms work? Addendum. Upon further thought, I do see your point about the skating force changing direction. When the stylus is riding in the outer grooves moving toward the one instant when it is tangent to the groove, the tracking angle error is getting na... | |
| Koetsu cartridges - what arms work? Racedoc, did you actually make quantitative measurements of skating force? Or are you reporting your observation of what the tonearm does on a grooveless LP? In any case the skating force will be a function of the friction of the stylus in the gr... | |
| Contact lens cleaner for cleaning stylus cartridge ? Why take a chance? A company like Stylast makes products designed for cleaning a stylus. There are also a myriad of other ways to clean a stylus without using any fluid at all, such as by ultrasonics and using magic eraser and similar products. So... | |
| Dynavector cartridges, old and new Bimasta and others, my basic point was that my experience tells me that selecting a cartridge based on its having an exotic cantilever material or an exotic stylus shape or a rare or unusual magnet structure does not consistently result in a re... | |
| Valve phono stage Infection, You asked Atma-sphere why "top" phono stage designers use RCA inputs. Here's a list of reasons:(1) It's been the industry standard for so long that nearly all tonearm cables are built for SE inputs, and "top" designers do not want to ... | |
| Vintage DD turntables. Are we living dangerously? I neglected to note that the monster got the girl in "Young Frankenstein", not because of his superior intellect, if you know what I mean. Dr. Frankenstein did OK, too, with his nurse assistant. |
