Tips on Getting Perfect Alignment

|B. Recheck Turntable
For suspension turntables, arrange some books under the turntable. The top of the books should be very close to the turntable bottom but never touches it. This prevents the turntable from bouncing.

Power - Critical Element
|Best Tractor uses a fine line for
alignment reference. It is important that you use a good
quality 8X or above Magnifying Glass to view the stylus
tip spot on the fine line.
Viewing tool is very important and the 5X eyepiece on the left always tells you are spot on while the 10X Peak Lupe tells you are still way off, one side or the other.
Alignment game with Best Tractor is all about the 0.03mm distance. Many users who report excellent results agree with this.
|When using the Peak Lupe 10X magnifier, have the glass
pointing in front.
-- Place the glass real close to the stylus tip. And hand move the Lupe AWAY from the object to get the focus.
-- Have both eyes open. Look at the magnified image in a very relax manner.
This may not be the perfect tool for the purpose, but if we measure value for money performance we cannot find any other alternatives.
The Peak Lupe we recommend has got the power and good image. The drawback is it has a thick housing and this prevents it from viewing the stylus tip behind a very low cartridge wall.
In such case unscrew and detach the transparent lower half housing from the Lupe.
By doing this you may view the stylus tip at an angle. Not a perfect way but it works.
One important function of the Peak Lupe is to ascertain your
stylus tip [ie the diamond] is
put right spot on the Null Point sight line
for judging perfect alignment.
This is a most important step.
If the stylus tip is not on spot then the whole exercise becomes meaningless.

able to come to the above scenario after you have
ascertain the stylus tip falls on each and every point
onto the Effective Length Arc.

Some tonearms do not have azimuth adjustment. You have to help yourself.
Take some left over pieces of paper from your hole puncher. Use a small file or any point object to make paper shims for adjusting azimuth.
|This picture shows how to use the paper shims. It
takes one to three shims. More than this we would advise
you to put some paper shim to the armboard instead.
Paper shim costs nothing and sounds neutral.
Azimuth is critical!
For fine tune adjustment, put the stylus tip on a blank disc and look at the reflection. Use the 3X magnifier to help you.
Take a serious look at the diamond tip sitting on the disc. You have to listen to the music to decide. Adjustment should be done within the limit that the diamond tip must look good to your eyes - this is the most important reference.
There is a Youtube Programme on Azimuth by Peter Ledermann of Soundsmith. Excellent information please click the right hand link to watch it :
|F. Anti Skate
Again Peter Ledermann of Soundsmith has a details explanation on this topic. Part 2 he has made a suggestion on how to adjust the Antiskating force of your tonearm which is similar to what we are doing with our setup.
|For setting VTA, I suggest this
a. listen to a LP with bass - my reference is a Dire Straits - six blade life. But any LP of your like will do
b. lower the VTA by 0.2mm and listen again.
c. repeat this exercise until you are sure you have too much bass and the sound becomes murky.
d. raise the VTA by 0.2mm and listen.
e. stop when you have come to a music picture when there is a good balance of bass and highs.
I totally agree with Kuzma:
"Beware of falling into the trap of accepting a too HIFI sound as opposed to a less bright , less spectacular, but more correct sound."
Phono Amp Loading
This is a very important area of getting good sound. Again it is easy to make mistakes and one must preform a listening test to confirm the appropriate value of impedance loading.
I find the following link
very useful. It suggest we start a value with 25 times
the internal resistance of a cartridge and then perform
listening test within the range of +/-50% of the start
