| Does Your Linn Sondek Lp12 Motor and Pulley Get Very Warm After Extended Use? In your opening post, you said the motor and pulley were heating up after extended use. In your most recent post you say the motor and pulley are heating up when the belt is not on the turntable. Do you mean to say that the motor is heating up reg... | |
| Does Your Linn Sondek Lp12 Motor and Pulley Get Very Warm After Extended Use? Excessive belt tension? | |
| Yamaha GT 2000 with 40 pound copper platter. If you believe Vintage Knob, the GT2000 could be purchased with an optional high torque motor, the same motor that was standard on the X version. If I was going to use a 40-lb platter, I’d want that bigger motor. | |
| Direct Drive "the presence of a large oscillating magnetic device right under a very sensitive magnetic device." You're talking about the potential for EMI from the motor affecting the cartridge. Why not just say it that way? As I have mentioned many times,... | |
| SL-1200G/Hana ML Best Headshell Should have noted that when you multiply effective mass times compliance and take the square root, keeping compliance constant, then the ratio of the result with a 9g vs 12g effective mass is even less different than the square roots of the two nu... | |
| SL-1200G/Hana ML Best Headshell Think of it this way: square root of 9 is 3. Square root of 12 is ~3.4. So the difference between 9g and 12g is not going to affect the calculation of Fr by much. | |
| Analog Upgrade itch The Steelhead is compromised by its own very mediocre output coupling capacitors. And if you use it as a full function preamplifier, then the signal has to traverse two of those same mediocre capacitors. Upgrade the capacitors, then you've got s... | |
| Yamaha GT 2000 with 40 pound copper platter. Less rotational inertia, which is the main point of the high mass. But sure, it would “work”. Lower inertia would make it easier in the motor. | |
| Direct Drive Ketchup, I take the bearing as a given for any turntable of any type. So there is no special problem of a bearing in a DD type. All platters ride on some sort of bearing. Mijostyn, I don't know precisely how a Cosmos is constructed, but I do kn... | |
| Direct Drive Whatever Harry Weisfeld wrote on Audiokarma, it cannot be accessed unless one is registered over there. Sunnydas1, what is your point? In a direct drive turntable, you can think of the platter as the rotor part of a typical motor. As in a classi... | |
| SL-1200G/Hana ML Best Headshell If you look at the math, there is really quite a bit of leeway in effective mass and compliance that will give you a resonant frequency that falls within the typical range of 8 to 12Hz. And anyone who has done vinyl for a long time with a variety... | |
| Direct Drive I owe Mijo an apology. He referenced the STST because it is DD (and apparently suspended). So he was not being disloyal to his favorite suspended BD turntables, SOTA or Helix. | |
| SL-1200G/Hana ML Best Headshell Don’t bother. The titanium headshell is probably too heavy, if it really weighs 19 g or more. I’m not sure you would benefit even from changing the original headshell, but if you feel like experimenting, I would go with the carbon fiber headshell ... | |
| Direct Drive Mijostyn, Have you fallen out of love with the Dohmann Helix? Also, you can add a Herzan or Minus K shelf to any non-suspended turntable and be better off than with any spring-suspended turntable, BD or not, because all spring-suspended BD turntab... | |
| Tube PHONO preamp interference - RFI, EMI, bad grounding? Indeed, if the 33 ohm resistor was in series between the IEC and the ground lug, on the one hand, and the PCB ground, leaving everything but the PCB containing the audio circuit at earth ground, that would be OK. But I still don't think we've hit ... |
