Recessed Tonearm Armboards
A tonearm manufacturer once told me that a tonearm is restricted in movement if the armboard is recessed below the plinth. Now I have never owned a turntable that had a recessed armboard, but I have seen some that were recessed a few mm's to an inch, but nothing more than that. I wanted to know what is the reason that would cause the restriction or its ability to move less freely. Or maybe folks feel that it's just not the case.

My SOTA Sapphire has a recessed arm board, as it is part of the suspended sub-assembally. Thus, has to be free, slightly ‘floating’, below the outer body. No issues. Would have been had I purchased a popular third party VTA on the fly mechanism, but I went with the Jelco BA-1 instead. But even then, could have bought 1/4” spacers. Would have to be pretty recessed and small to restrict movement, seems to me, and at that point you would probably run into worse problems, depending on the height of the platter. |
Thanks @bkeske - was having a hard time finding a picture to illustrate. Good to hear that you are not having any issues. As Lewm indicated, not every tonearm/table may have issues with recessed armboards. Not to cloud things, but there also is a platter to plinth or top of armboard height requirement that most tonearms require. @millercarbon - click link for a picture to see what I'm talking about. https://sotaturntables.com/restored-turntables/ |
Depends on the tonearm design, some tonearm counter weight can cause problem if the recessed opening is too small. https://i.ebayimg.com/images/g/ZY4AAOSw~OVWvyCg/s-l1600.jpg https://www.analogueseduction.net/user/products/large/morch_dp8_16.jpg |
