RB300 maintainance...

I've made the test proposed by Lugnut and I noticed that on perfectly leveled TT the tonearm comes always back even with anti-skate set to zero.
On my opinion it's azimuth mis-adjustment. The only way to bring it to the appropriate level is to use the file to cut off a-little one of the plastic spacer that is a partof the armboard. While the TT is leveled perfectly the armboard isn't.

Marakanetz,

Understand, I have never actually seen your brand of turntable in person but looked at several photos on the net. Since it is a suspension turntable I make the assumption that the platter and the armboard are somehow suspended together. That would mean that the platter and the armboard are level on the same plane. You mentioned that you have perfectly leveled the turntable. If you place a spirit level on the platter and it shows level, does it also show level on the armboard?

Please post your progress on this thread. Good luck and...

Happy listening,

Patrick it's yes and no. Theoretically it's yes and practically the level isn't matched on the armboard(very-sligtly off) due to probably the slight difference between one of the three cylindrical plastic 1/2" spacers that mounted on the plinth first and then the armboard(sooner or later I'll probably get the fully adjustable tonearm like Act5 or SMEIV). So once I start(I've even placed two bubble levels onto plinth and the armboard)leveling the armboard the plinth is completely off the level. Currently I've found the "average" balance between the armboard and the plinth which took care of some inner-groove misreading. The more I'm dealing with Rega the more I realize that it's not the way to go.

Marakanetz,

I think you have found the problem. One of the most difficult things to accomplish with my Linn is to get the armboard level with the plinth while having the suspension respond correctly. In the case of a Linn, if one "pushes" down on the platter in a line from the spindle to the arm mount, the susupension should move up and down when released, not sideways or circular. Once I get that right the plinth and the platter/armboard are very close to being level at the same time. This where it sounds best and thankfully, once done, rarely needs to be done again. The Rega is an excellent value so I'm sorry to hear it may not be right for the application. You may need to inspect the susupension more closely as described above. Keep us posted.

Happy listening,
Patrick

Patrick, Rega is an excellent value but the Rega's philosophy is to place too much demand on the turntable isn't sometimes appropriate. I believe that adjustments to turntable/arm for the sake of maximum cartridge accuracy must be mutual. If I were using fully adjustable arm that would not be a problem at all. Now I'm mobilizing my file to scratch the right plastic sylinder and than measure the level every time I scratch or maybe I'll be cutting plastic spacers from soft guitar pick so I will not do any damage to an original settings.
