| The pivoted arm experiment is over Anything that is good for a high quality arm should do fine. It should not matter whether the arm is straight or radial tracking. | |
| My Nak 505 sounds like its going thru a phase shif You will also want to keep the capstan clean. This is the small rotating shaft that the pinch rollers bear against. It should look nice and shiny- any texture means its dirty.Dirty pinch rollers can be caused by tape shedding and the rubber of the... | |
| Hum from Grado on LP12.. Better carts to consider? If the motor is made of a metal that can be soldered, then solder it. Otherwise a wire with a lug, placed under a nut and bolt should do the job. | |
| Hum from Grado on LP12.. Better carts to consider? Geor, they may have springs but that cannot be considered an adequate ground. The motor must have a wire that does the job, so plinth, motor, platter bearing and arm have the same ground.The motor may not be shielded, but if you ground it that may... | |
| Turntable speed slow with quartz lock First, try cleaning the speed selector switch with Radio Shack electrical contact cleaner. If you have variable speed controls, clean them too. I would not do anything else until you have done this- this is a very common problem. | |
| woofer pumping Newbee got it. The first place to start is the arm/cartridge compatibility. Not only will you reduce woofer pumping, but you get better sound if the cartridge and arm are working together. | |
| Hum from Grado on LP12.. Better carts to consider? Grados will hum with certain 'tables, like the Rega. Usually this comes from the table not being sufficiently grounded. For example, the Rega needs to have its motor and platter bearing both grounded to the arm ground. I suspect the same is true i... | |
| Atma-Sphere MA2 Mk2.3 / Krell KSA 250 / Passlabs? Jtimothya, you might want to try that experiment again while using a 600-ohm termination at the input of the amplifier. The MA-2 is equipped with a switch that allows you to set that termination if the preamp supports it (the MP-1 does). If there ... | |
| 2A3 Set power amp The reason SETs have that amazing 'dynamic' character is all about how they make distortion. At very low levels, the distortion is unmeasureable. But at full power, the distortion is 10% and includes odd ordered harmonics, which are loudness cues ... | |
| really? .89c ground lifters? Jea48, I wouldn't call that a ground loop. If there was something like that, it would cause the ground to be noisy. While a ground loop is also a noisy ground, the difference is that the former is caused by a malfunction rather than a gain stage l... | |
| really? .89c ground lifters? Yes, it does not matter tube or transistor. The real issue would be if somehow there is leakage from a power transformer. | |
| Power output of tube amps compared to solid states Yes, just as they also made a dedicated tube OTL-powered speaker. | |
| Power output of tube amps compared to solid states Emorrisiv, I've heard the Acoustats sound great with a set of M-60s and a set of ZEROs. The guy that had them also had an ARC Classic 60, and he had to use the ZEROs with that amp also. They seemed to otherwise present a challenging load for a tub... | |
| Half speed master OK- any cutter head you can think of has a resonance that occurs at a high frequency. My Westerex 3D (which is what RCA used for many of their Living Stereo releases) for example. No amount of messing with the suspension seems to affect it. To dea... | |
| Dynaco ST-70 The ST-70 can be driven easily by any preamp made. The real issue is that the speakers are low efficiency- 88db, so the issue is whether or not 35 watts will be enough in your room with your listening habits. |
