    Default Rega Planar 1 anti-skating issue.

    Hi!

    My name is Andrey. I'm a newcomer at this forum and actually in a world of analogue equipment. When I've decided to purchase a TT I did not know much about it and a quick research lead me to Rega Planar 1 as a good choice for beginner for a reasonable price , so I baught it with Rega Fono MM. I was happy with the quality of sound, but as usuall appetite comes with eating, so rather quickly I began to think about upgrading cartridge. The most obvious choice was Rega Elys 2 cartridge, cause of its good reviews and full compatibility with a TT, as it was said in a manual. I aquired it, but a very annoying problem revealed, that made me think that upgrade descision was a bit premature. The problem is pre-set anti-skating of RB110 tonarm, which is set for 2g without ajustment ability. It is perfect for Rega Carbon with 2,5g recommended downforce, but too much for Elys 2 with 1,75g, so when setting counterwheight to this value, the tonarm begins to slide to the right, which causes playback problems and, as I can guess, exessive pressure to one side of the groove, which cannot be good for records. Of cause, afterwards, when I searched the internet, I read, that it is a well known issue of Planar series and that people solve it by unmounting the anti-scating magnet which is glued inside the tonarm, but for now I think this measure is too radical.

    Maybe someone already dealt with changing cartringe on Planar TTs ?

    How did you solved anti-skating mismatch issue ?

    Thank you!

    I was not aware that Rega made an arm without Anti Skating adjustment. I hate to say this but, without that ability I think you have to stick with Rega's cart of choice for that arm. I get it cuts costs to omit anti skating adjustment, but to do so basically makes that arm incompatible with so much, I could not myself personally recommend that arm.

    There is no tweak that I can think of that would sort this design omission.

    Thanks! I see....another question then: based on your experience, how critical is setting higher downforce for the cart then recommended ? What kind of problems could setting it for example to 2-2,1g (while recommended is 1,75) cause ?

    Andrey,

    I suggest that you contact Paul Darwin, the managing director of Rega, on PinkFish Media (PFM). PFM is another UK hi-fi forum and Paul will normally answer queries directly and offer to help.

    Hm. Paul's answer looks veeeery confusing.

    Here are the specifications from Rega official site:

    http://www.rega.co.uk/uploads/carbon-leaflet-eng.pdf
    http://www.rega.co.uk/uploads/elys-2.pdf

    Also, I have electronic scales and I have checked the downforce, when the counterweight is pushed all the way to the collar. It is 2,5g....

    It becomes stranger and stranger...

    Using stylus scales you can set the tracking weight with the Elys-2 to the recommended 1.75/1.8 weight. The pre-set bias is an approximate value but perfectly suitable for the Carbon and/or Bias-2 or Elys-2.

    What I believe you are saying is that when setting the tracking weight, the arm swings outwards. If that is what you are experiencing, then that is perfectly normal. It's a bit annoying because you can't disable the bias, but is not a problem when playing records at the recommended tracking weight and it won't cause any "playback problems".

    I have done just this on a couple of occasions and had a few customers upgrading their cartridge on a P1 or P2 and there are no problems with these combinations.
