| FR64S tonearm overhaul I agree with Nandric - dont touch the FR64. The FR's have excellent bearings, better than most arms today and I would not risk disturbing them. The Cardas wire in my view is not worth the investment. Firstly it is a springy wire and tends to exert... | |
| Turnable database with TimeLine 01-05-14: RichardkrebsRegarding the eddy current brake as used in the Beat TTGo to teresaudio.com and follow the link...micro precise speed technology.The Certus motor.As I said earlier, this is an elegant design.You have incorrectly claimed that ... | |
| Turnable database with TimeLine 01-05-14: RichardkrebsRegarding the eddy current brake as used in the Beat TTPlease quote the authority to substantiate your assertion that the Beat uses an eddy brake ? | |
| Turnable database with TimeLine LewmInteresting you mention the Kodo Beat. I have been following the evolution of this TT with interest, given it uses similar principles to the Final Audio.01-04-14: RichardkrebsThe Beat appears to uses electromagnetic drag to "pre load" the moto... | |
| Turnable database with TimeLine Addendum to above post :The big Micro's use DC motors with frequency generated servos built into the motor. So their response to speed issues has the same issues as the direct drive, the main advantage of the micro's is the large inertia. This wou... | |
| Turnable database with TimeLine 01-03-14: RichardkrebsYes the Goldmund used a JVC motor.Like, I suspect most DD designs, it is a synchronous motor. The rotor ( platter) is compelled to follow the rotating field, back slightly in phase. I'll explain how the Goldmund motor really ... | |
| Turnable database with TimeLine 01-03-14: RichardkrebsMany years ago I owned a Goldmund Studio. In an attempt to improve it, I built a larger power supply. I scoped the supply output while playing a record. To my amazement I could see the supply output voltage being modulated by... | |
| Turn table speed variation question Halcro Your DD has stylus drag as well. The only difference is that it is dealt with by the speed servos. Some belt drives have servos, some have self correcting AC motor controllers.One could argue that the speed correction for the stylus drag in... | |
| VPI bearing oil/grease? Slaw, thanks for the feedback on the Motul V300 oil. Pleased to see you are happy with the outcome. I have also used the Motul V300 to great effect in lubricating the TT motor. In the Final TT the motor is fairly large and has a spindle/thrustpad/... | |
| VPI bearing oil/grease? Brf,The Final Audio uses oil in an inverted bearing. The tolerances are very fine and the oil holds. Reseating the subplatter/platter takes about 6 hours when I change the oil. In the 25 plus years I have owned the Final it has never run dry.Most ... | |
| good preamp for dynaco mk3 monoblocks with maggies Zvovchik,up to $1k I would suggest Audio Research SP9mkII ( about $8-900) or SP16L ( about 1k) as being good value and good bang for the buck. The SP9 is a hybrid design and has lots of drive in the line stage. The SP16 is very musical. The SP11 y... | |
| Turn table speed variation question [/quote] 12-19-13: HalcroWhen I listen to acoustic guitar on my Victor TT-101 DD turntable with unequalled speed accuracy......an off-centre record hole will be mercilessly exposed. :-(Halcro - you are ready for the next big upgrade......Nakamichi... | |
| good preamp for dynaco mk3 monoblocks with maggies I dont agree with the TVC solution suggested for the following reasons :The Dynacos do not have a very sensitive input stage and sound much better driven from an active preamp with good voltage drive. I own a pair.Secondly, TVC volume pots have ph... | |
| VPI bearing oil/grease? Frogman/Slaw,If you can, try and get some Motul V300 Power Racing, either 0W30 or 5W40.It is simply the best synthetic oil on the planet, a double ester synthetic, using extract from Copra. It is highly unctuous, which means a film will adhere to ... | |
| Eminent Technology ET-2 Tonearm Owners Richardkrebs and readers of this thread,My apologies to all for not having responded earlier, neurosurgery has precedence. Richardkrebs has been advocating changes to the ET2 that include adding mass and removing the patented decoupled counterweig... |
