| Detachable Head shell or Not? Evidently the Tru-Glider is an underhung tonearm with zero headshell offset. That’s cool! However the website contains BS typical of other manufacturers of underhung tonearms. They don’t seem to understand their own product. To wit: the claim is f... | |
| Detachable Head shell or Not? I’ve thought long and hard about doing that for the Kenwood L07J tonearm, the standard tonearm on the L07D turntable. Just to bypass their own IC and their internal tonearm wires, which are both the original Litzwire type. The Kenwood OEM IC must ... | |
| Phono input cap to preamp I couldn’t download the article without paying a fee. However it’s been referred to in several ways at various sites. Seems C1 and C2 are tantalum in the OEM circuit. Tantalum’s are polar and correct orientation is mandatory lest they catch fire. ... | |
| Detachable Head shell or Not? Jafox, Given the difficulty you describe in comparing tonearm with vs tonearm without, and with which I agree, I choose a second best option, which is to listen for several weeks on a regular basis to one setup in my own system where I know intima... | |
| Hum with Ypsilon MC26L SUT that goes away with touching Seems the problem was solved by the OP in August, 2020. | |
| Detachable Head shell or Not? Jafox, you’re replacing one conjecture with which you don’t agree with another conjecture that suits you. By the way shouldn’t the comparison be between tonearm A that has a permanent headshell, where the wiring runs all the way from cartridge pin... | |
| SUT Interconnects Shielding adds capacitance. Cable geometry also affects capacitance. The 12AX7 tube, often used as the input voltage amplifier in tube MM stages has a high Miller capacitance that adds to cable capacitance. Transistors also add capacitance at the ... | |
| Detachable Head shell or Not? Aulait, my ears tell me there is a benefit associated with a direct wire connection. Is it night and day, and can I measure it? No. As to Richard Mak; I don’t know who he is. Difference I hear is for low output cartridges only. I don’t know why Mi... | |
| Phono input cap to preamp Also, C1 and C2 protect the coils of an MC cartridge from any DC offset at the transistor gate. I’d love to have that confirmed or refuted by any pro in the audience. Thx. | |
| My Elkit TU-8600S build review and questions DC voltage is almost always a constant in a circuit such as yours. So you should not think twice about that issue. Also carbon film are far more stable than CC types. One issue with CC types is drift of the resistance after repeated heating. CF wo... | |
| Detachable Head shell or Not? Mijo, are you thinking of the Z06 Corvette? Or is there really a plan for another ZR1? My friend and I have reserved a Z06, 50-50. But I want a Ferrari. Pre-owned is ok. | |
| Pioneer SL-570D TT Tonearm Suggestions On their upper tier turntables, Pioneer tonearms were excellent. I concur with others that your probably best off leaving well enough alone. | |
| Pioneer SL-570D TT Tonearm Suggestions Any good tonearm would do but the constraints on your choices have to do with the effective length and pivot to spindle distance and the specifics of how the OEM tonearm is mounted. None of these parameters are known to anyone but you. Not to say ... | |
| Phono input cap to preamp I looked up the schematic. C2 is the top half of a capacitative voltage divider network. C1 is the other half. Together these act on AC frequencies delivered to the input transistors. R1 is your phono load resistance. I have never seen this topolo... | |
| Phono input cap to preamp You got a plausible explanation for the capacitor from Atmasphere. I wouldn’t second guess him, but I do wonder why Hafler chose to use 10uF there and why he didn’t use a film cap, as well. Is this an MM stage or MC? If MC, what is the value of th... |
