Can anyone here emulate this - The Final Audio turntable can maintain speed whilst someone is banging on the record with bare knuckles while it is playing ....Bare Knuckle speed testHigh torque AC synchronous motor with decent power supply, 22kg P...

Halcro = I dont own a timeline, I borrowed it from the local audio shop here. At some stage when I can get hold of it I'll post a video. The Albinoni is great. 
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...

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...

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...

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 ...

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...
