| Tables That Feature Bearing Friction *** Well - the physical phenomenons regarding the turntable CAN and ARE fully understood. Unfortunately and apparently not by the majority of turntable designers. ***Some of the phenomenons are well understood but many are not. Please explain why ... | |
| Tables That Feature Bearing Friction Yep, expensive is the hated word for the day. Expensive applies to both commercial and one off, all out assaults. It's just that the threshold for a one off can be much higher. Maybe a solid gold platter would sound really good...For me expensive ... | |
| Tables That Feature Bearing Friction Dertonarm, I completely agree with you that the job of a turntable motor is only to bring the platter up to speed and then keep it from slowing down. Where I disagree is that platter mass alone is the the cure all for speed stability. A large plat... | |
| Tables That Feature Bearing Friction Dertonarm, we are talking about physics. The issue of stylus drag has been hotly debated before. It is a fact that any drag, regardless of how small will slow a platters rotation. A large platter mass spreads the variation over a longer period of ... | |
| Tables That Feature Bearing Friction Dertonarm, the heavy platter, slip coupling approach focuses on only the issue of motor cogging. This approach does not deal with the issue of stylus drag, or any other variability in drag. Contrary to popular beliefs platter mass changes how styl... | |
| Tables That Feature Bearing Friction Dgarretson,I addition to the practical difficulties that Dertonarm pointed out there are some good theoretical reasons against using a flywheel at the motor. In all motors motion is produced by magnetic attraction. When there is no drag themagneti... | |
| Verus Vs Rim Drive The standard Verus motor drive wheel overhangs the motor pod by 0.4". We have an optional drive wheel that is larger with an overhang of 0.8" that works with the Scoutmaster. | |
| Probelm with my Teres motor Sounds like the motor shaft is pushed out of position. Too much pressure on the end of the shaft will shift the rotorcausing it to rub on the internals. Not difficult to fix, give me a call. | |
| Would Like To Hear From Strain Gauge Owners Raul, You still don't get it. I suggest that you read this and other responses carefully before responding. 1) The RIAA curve is about flat frequency response. The record is recorded with the inverse of the RIAA curve and applying RIAA equalizatio... | |
| Would Like To Hear From Strain Gauge Owners Peterayer, No, I don't think the debate is about the RIAA curve. It's an old, tired argument that Raul brings up at every opportunity. Raul has seems to have an obsession with flat frequency response. Anything that does not have ruler flat respons... | |
| Teres Composite Platter, etc. The primary reason for dropping the 200 series turntables is simplification. Being a small operation we need to limit our offerings. Keeping up with Verus, Certus and 200 series orders was pushing us to the limit. When we decided to pursue develop... | |
| Teres Composite Platter, etc. With great reluctance we decided to not produce any more 200 or 300 series turntables. We have a few model 260 and 265 turntables in stock, but no platters of any kind that we can sell separately.We do get trade-ins from time to time, but it's rat... | |
| 2008 RMAF – – – all things analog. Robdoorack, Thanks for the interesting data. The measurable deviation cited was more than I would have expected. As Doug points out the measurement time period is very significant. Most people are not able to detect relatively large errors in aver... | |
| 2008 RMAF – – – all things analog. Jj2468, I should have mentioned this before. There are various types of speed anomalies that that are not manifested as pitch fluctuations. Very short term speed variations show up as smearing, lack of detail and often harshness. Longer term, shal... | |
| 2008 RMAF – – – all things analog. CD = Perfection... except for jitter. Timing errors seem to be an achillies heel for both analog an digital. |
