| Why do I need power management if I have a great power cord? raysmtb1 ... When I listen to my Mcintosh 611 mono blocks the meters usually say that they’re drawing around 6 W each ... if you do the math for watts to amps that means that the amp is only drawing .5 amps each Those meters show powe... | |
| Resistors fiesta75 Resistors are never used as fuses, how he thought they were, is beyond me! You are mistaken - it's actually not that unusual. ARC, for example, often uses resistors as fuses on its power amps and also on the 6550 in the PS of i... | |
| Amir and Blind Testing bubba_buoy We cannot measure the difference between a middle C, played on a properly tuned clarinet vs. a synthesizer, vs. a trumpet. It's trivially simple to measure the difference between a clarinet and a tru... | |
| The best phono cartridge alignment tool wlutke Here’s a tip for finding the pivot on a Rega and some other arms when using the Feickert. With the arm on the lift I place a 3/8” square of sticky note with a dot in the center over the pivot. With the Feickert pointer over t... | |
| If it does not work, read the manual FTFM. | |
| The best phono cartridge alignment tool I have plenty of alignment tools, going all the way back to the original Dennesen, which was excellent. Of them all, my favorite is the original Wallytractor. These were made specific to each arm, unlike their current universal model. What's great... | |
| TT speed holmz I am the OP, so it was my fantasy not @dover . Oops, my apologies to @dover and you. That's a mistake I really try to avoid. It is not “tangency”, but the walking of the point across the platter dues the arc of the tone ar... | |
| TT speed holmz if we change the speed of the patter we would alter the tone’s frequency. Yes. The tracking of a pivoting arm would look equivalent to linear motion of the overhang, moving slowly, in a linear tracker arm. What you’re saying i... | |
| TT speed lewm Everywhere at any point on this LP, the 1000Hz test tone has been encoded by a perfect cutter lathe. In practice, the stylus tip is just a point on the surface of the LP; it doesn’t "know" where it was a fraction of a second before... | |
| Amir and Blind Testing teo_audio I could go on for pages and pages more, but the end point is that physical measurements as they stand, connected solely to engineering criteria and weighting, fail to take into consideration the capacities of the human ear and... | |
| TT speed It’s interesting how some people think math is intuitive, and that they’d rather pursue a fantasy than understand what is really basic math. What’s odd is that they’ll resort to such personal attacks and invective in defense of a fantasy, while at... | |
| TT speed dover Assuming the record is travelling at constant speed, then the motion of the stylus forward and back relative to the line must alter the apparent speed, as seen from the record groove, albeit minuscule. You are really confused. Yo... | |
| TT speed mijostyn Theoretically pitch is affected but the effect is so slight that it may well be unmeasurable. We've already shown that measurements reveal it doesn't exist. It's easy to measure a 1 kHz tone on a test record. ... the tu... | |
| TT speed holmz ... the error would need to be less than the W&F “noise”, and my stab at the error would be about 0.11 Hz at 1 lHz. You're arguing that tangency affects pitch? If so, that violates the Fourier Transform. That's not possible and... | |
| TT speed dover ... on a pivoted arm the stylus is advancing and retarding relative to tangent, therefore there must be a timing error ... Your belief is easily disproved with a test record - it’s easy to measure the frequency of a test tone on... |
