| Grado Epoch 3 I can't think of any reason to do jeweled bearings on an EPA arm aside from nostalgia. It's also exceedingly difficult to get anything approaching grade 5 or better. Last I looked grade 25 is all that was reasonably available. | |
| Direct Drive @pedroeb "Where do I get 3 phase when my house is only single phase? Surely AC motors are asking for trouble." Two entirely different things. Phase does not necessarily mean AC, and AC does not necessarily mean sinusoidal. In these instances ... | |
| Direct Drive @dover "Any of the vintage use DD's use 3 phase motors ?" This caused me to try to think for a moment of one that isn't at least three phase, and I'm coming up empty. | |
| How important is the cable between the SUT and phono pre? Thanks, but as I’ve said a couple times now that wasn’t the issue. | |
| How important is the cable between the SUT and phono pre? No, that's not the problem I was having. Worked through it with a friend and see that I was not correct. Regardless, something that actually explains it would be beneficial. I like to enhance my understanding of things, not just parrot what som... | |
| How important is the cable between the SUT and phono pre? Thank you for the reference. Section 1.2.4 is in regard to inter- and intra-winding capacitance and electro-static shielding, which I understand. While Figure 16 depicts secondary load C as CL, I do not see a reference to it in the text. This s... | |
| How important is the cable between the SUT and phono pre? Would love to see a cite with a detailed technical explanation. I can’t find one, equivalent models I can find don’t show it, and a couple EEs I’ve talked to say it doesn’t. Repeating a formula is not an explanation. | |
| How important is the cable between the SUT and phono pre? Hi @imhififan, he's basically explaining a zobel like I mention above, and some generic advice that may or may not fit a circumstance. However, transformers do not reflect secondary load C to the primary. | |
| How important is the cable between the SUT and phono pre? Impedance != capacitance. | |
| How important is the cable between the SUT and phono pre? @jasonbourne52, it's not quite that simple for MM as increasing capacitance will also move the resonant frequency down, depending on the electrical characteristics of the generator, of course. This is why on a cartridge like the AT150MLX, if you ... | |
| Tonearm for Technics SP-15 The ground pin is the same size an RCA center pin. Easy peasy. | |
| Interesting information from Analog Planet on Stylus Cleaner Onzow Zero Dust. I've used ZeroDust for over a decade. Just checked all my styli/cantilevers under the microscope, and not hint of this problem. | |
| Have a Victor UA-7045 tonearm coming I emailed you back quite some time ago. | |
| Tonearm for Technics SP-15 I switched from Triplanar to Technics. |
