Universal Protractor

We have revised our famous „Universal Protractor“. Besides making handling easier we have enhanced the functionality as well as accuracy. On this Protractor you can find all three well known, major geometries aka Baerwald, Lofgren and Stevenson.

Theory

The general geometrical correlation of a tonearm based on a fixed pivot point are well known since the fundamental publications of Baerwald and Lofgren back in the first half of the 20th century. The conclusion of both papers was that such a tracking device must have an angular offset (zenith) with a defined overhang. The offset and the overhang vary with the effective length of the tonearm itself. While tracking the record the stylus matches tangential position in the groove at two points – the inner and outer Null points (linear tracking position). In the early 1960ies another mathematician has calculated a new set of parameters taking into account that on records with classical music very often crescendos occur towards the innermost grooves (Stevenson).

How to - step 1

Choose the geometry you want to use: Baerwald (B), Lofgren (L) or Stevenson (S).

Screw the gauge tower on the disc and place the Protractor on the platter. Aim with the pin in the gauge exactly over the pivot point of the tonearm. Move cartridge in the headshell so that stylus lands on the crosslines of your chosen geometry (B, L or S) at step 1 (overhang). In case you cannot reach either point on the Protractor please check your pivot-spindle distance.

Carefully tighten one screw a little bit and make sure you can still turn the cartridge in the headshell. Set antiskating to zero.

How to - step 2

Turn Protractor so that you are over area of step outer Null-point). Set angular offset (zenith) so that the printed line on the Protractor and the cantilever of your cartridge fall in line when looking from the front. In case this is done carefully tighten both screws in an alternating way and take care the cartridge doesn‘t move anymore in this process. Caution! Don‘t overdo the tightening of the screws as really tight is followed by infinitely loose forever …

Double check your setup either at step 3 (inner Null-point) where the cantilever MUST fall in line with the printed line or you can alternatively check the overhang again at step 1. Both approaches are mathematical equivalent; if two points are correct, the third is correct by default. In case the cartridge still is off, then start again from the beginning by checking the overhang first and subsequently all the following steps again.

Not great at cooling
Size: Queen (2 Count), Color: Original White (Cooling)
Each pillow cover has 2 sides, one marked for cooling, and the other a different fabric. The cooling side is about the same effectiveness as having a silk or satin pillow cover. It's only cool when you first touch it. The cooling side doesn't seem to absorb or wick moisture, so if you are sweaty - it keeps the moisture in place. You'll definitely want a regular pillow case over the pillow cover. In fact, if you suffer from night sweats, the non-cooling side is actually more comfortable. The pillow fill is ample, and simple to squish around for more support for your neck, etc. Think bean bag. But it will retain your impression after use. I find I need to do as I did when I had down pillows - give it a few good shakes in the morning when I make the bed to get it evened out for the coming night. In all, it is a well-made and comfortable pillow to sleep on, but it does not excel in cooling.

excellent pillows i bought two sets!!
Size: Firm Queen (2 Count), Color: Original White (Cooling)
I ordered these for my son who has neck issues and has gone through so many pillows trying to find one that he liked. They’re heavy, so i was worried that they might be “too” heavy to be able to sleep on comfortably, so I ordered a second set, one firmer than the other (just in case) and gave him a set for Xmas and he loved the first set so much without even trying the less firm ones.He also needs the cooling factor and these offered that, too. They are filled with pieces of memory foam (tons of it) and each pillow can be modified by removing some of the foam. The covers are beautiful, high quality fabric with a zipper so ts easy to remove or replace the foam pieces. The size is perfect and they keep their shape. I kept the second set i ordered rather than returning them and i love the pillows. I actually modified two by removing some of the foam pieces. I kept the foam pieces in a zippered pillow protector and i can always adjust mine when or if i need to. 1000% love these.

The Perfect Firm Pillow l
Size: Queen (1 Count), Color: Original White (Cooling)
It is everything it claims to be, cool, comfortable and strong. I got this for my husband first, he loves it and then got one for my son, he uses it to support his knees and has been sleeping much better since then. They both needed a firm pillow that is not super soft, firm but not achy. Finally found the perfect one.

Comodidad total durante el embarazo
Esta almohada en forma de U ha sido una de las mejores compras de mi embarazo. Brinda soporte completo a la espalda, la pancita y las piernas, ayudándome a encontrar una postura cómoda para dormir. Es muy suave, no se aplasta y se adapta perfectamente al cuerpo. Desde que la uso descanso mucho mejor y me despierto sin dolores. Además, la funda es agradable al tacto y fácil de lavar. La recomiendo totalmente a futuras mamás que buscan dormir mejor y sentirse más cómodas. 💕

Comfortable accessory
This U-shaped pillow is made with a soft exterior material. The overall shape and flexibility allows for comfort in a number of different positions. I was expecting a pillow that was slightly more firm, however, it suits the intended purpose. The cover is removable and machine washable.
