Great Experience with Feickert Protractor
cleeds, Perhaps I misunderstand what you are trying to say in response to dang, but he is talking about turntables, not tonearms.  In fact, there are at least 3 different "standards" for spindle diameter.  As you might guess, it is critical for an...

Raul, You equate tracking angle error with audible "distortion".   I am skeptical that this is a valid assumption.  (The key word is "audible".) If you are so sensitive to tracking angle error, why are you even bothering with pivoted tonearms?  Yo... 
Dr. Feickert Protractor
I am sorry to learn that your system is not accurate enough to allow you to perceive the obvious distortion that I heard when I set up the DV505 for Baerwald. I am joking, of course. But why would you say such a silly thing? Any alignment geometry... 
Dr. Feickert Protractor
My one experience is with the Dynavector DV505, which is unique, as you know, in having two independent pivots, one for horizontal and one for vertical motion of the arm wand.  The DV505 was designed for the DV alignment, which is very close to St... 
Dr. Feickert Protractor
If you're concerned with only one tonearm, then I agree with Raul that the Mint LP protractor, which you have to order specifically for each tonearm and each different alignment algorithm you may want to try, is more cost-effective.  However, if y... 
Vintage DD turntables. Are we living dangerously?
I am going to guess that you replaced the wire that was broken with that thin gauge green insulated wire, seen in the last photo at about 7 o'clock on the face of the PCB.

And don't lose any of those five copper washers shown in the photo.  Also, when you put the motor back together, make sure you put the washers back exactly where you found them, as they effect critical spacing between rotor and stator inside the m... 
Vintage DD turntables. Are we living dangerously?
With all due respect to Mr Thalmann, he did not repair my TT101, perhaps because my TT101 always worked properly when it was at Bill's shop in Virginia. That is to be expected when something is "intermittent".JP fixed my TT101, and it still is wor... 
Vintage DD turntables. Are we living dangerously?
I still don't understand what you are observing.  Let me guess: the turntable comes up to speed and works normally for "2-3-5-7 hours" and then...  Here is where I lose you; does the motor stop driving the platter and then does the platter coast t... 
Has anyone heard the Miyajima 'Snakewood' cartridge,
Nandric, Once you squeeze all the oil out of it, snake wood is really hard. 
Moving a 5,000 vinyl LP collection safely
Now that that's solved, what town are you moving to? 
Vintage DD turntables. Are we living dangerously?
I didn't mention potential problems with ANY old turntable, such as issues with the bearing and spindle shaft.Also, best-groove, it is probable that your turntable needs calibration. As I understand it, calibration involves equalizing the impulses... 
Vintage DD turntables. Are we living dangerously?
Dear best-groove,What do you mean when you say the "engine started to lose laps inexorably"?  It would help if you can make the problem more understandable.  However, I also think that it would be impossible for any of us to say categorically what... 
Upcoming Technics SP-10R (100th Anniversary Model)
I think what Ralph is saying, and I agree, is that the square shape of the escutcheon surrounding the platter makes it nigh impossible to mount a 9-inch tone arm, at least one of the type that Ralph and I are fond of, where the bearing assembly is... 
Mullard cv4003 & 12au7 Blackburn
msommers, Perhaps I shouldn't write this, since you've already spent your money, but IMO the best sounding 12AU7/ECC82/CV4003 is actually a 6CG7 (in 9-pin miniature format) or a 6SN7 (octal base).  Neither of these tubes is in the 12AU7 family but...
