| Phono Box DS3 B output impedance 1.66K divided by 200 = ~8/1, so not quite 10/1, but the difference is trivial. There is nothing magic about the 10X rule of thumb. The fraction of signal voltage transferred is defined by the fraction Zi/Zo+Zi. When the ratio of output to input Z... | |
| How often to you clean vinyl and the needle? I wonder how many of us who rarely clean their styli ever look at the stylus under high magnification after long term use. If you did you’d be motivated to clean the stylus every few sides. I routinely use Magic Eraser but to be really thorough I ... | |
| Phono Box DS3 B output impedance Lanx, The OP wrote above that he is driving a 1.66K input impedance. And I think that's no problem, even if the output impedance is 200 ohms. | |
| Phono Box DS3 B output impedance If it's 1.66K ohms input Z, then you are probably OK, but I don't blame you for wanting to be sure, because unless the output Z of the DS3B is under 200 ohms, the ratio of output Z to input Z might be a shade lower than 1:10. On the other hand, i... | |
| Phono Box DS3 B output impedance I can’t find it, either, but assuming you own the all solid state DS3B, the output impedance ought to be very low, in the range of 100 ohms give or take, which means it can drive any linestage you’d care to use. Is there some reason you need to kn... | |
| Audio Technica AT 1005 ii or Fidelity Research FR54? If you go with a known 5mm error in pivot to spindle distance, then other compensations in overhang and headshell offset angle would have to be introduced, if you want alignment to conform to any typical algorithm. There are tables on line to hel... | |
| Wow & Flutter measurement I am curious why you ask the question. Every TT has some inherent wow and flutter, and every LP has some wow and flutter of its own, due to warps, off-centeredness, and/or flaws in the mastering process. I am just wondering why you want to measure... | |
| Hana Umami Red review Some great cartridges can pass through a phase where they sound downright mediocre or bad, during break in. Likewise, early ecstasy can turn to long term meh. | |
| Any experience adding a LPS to a stock Sutherland Duo phono stage? I assure you that the power supplies in your Duo are already "linear" type power supplies. The term refers to a conventional method for deriving DC voltages and current to run the audio circuit. AC from the wall goes through a transformer to alte... | |
| Any experience adding a LPS to a stock Sutherland Duo phono stage? And by the way, you would need two separate PSs or you would need to re-wire the unit to run. off a single PS that could supply both audio circuits. That's a complex job. Even to bypass the built in PSs with a pair of external PSs is not trivial... | |
| Any experience adding a LPS to a stock Sutherland Duo phono stage? Requires two power cords because it is dual mono. "Dual mono" means that each channel is completely discrete from the other, including the PSs, all the way back to the wall socket. So, you naturally need two power cords. This is a design feature, ... | |
| Any experience adding a LPS to a stock Sutherland Duo phono stage? You might provide more information for those of us who are not Sutherland aficionados. Is the OEM PS outboard or built into the main chassis? That’s the first question, because if it’s outboard, then it should be a simple matter to replace the PS ... | |
| Turntable Mats for Technics Grand Class, "G" Series Three of my 5 turntables sport a Boston Audio Mat, either the 2mm or the 3mm version. I use the SAEC SS300, on my Victor TT101. I realize there are some theoretical reasons not to use a solid metal mat, but I have been happy with the SAEC, nevert... | |
| ATN160ml Beryllium MicroLine Stylus on AT150e body I am not sure what you are responding to. Is it my weak joke about "happy tracking"? Sometimes I just cannot resist a good straight line. Pun intended. | |
| Turntable Mats for Technics Grand Class, "G" Series I like Boston Audio graphite mat on my SP10 mk3. BA don’t make it any more but someone else does. Sakura???? |
