SOTA Sapphire Turntable setup - how much lead?


O ye men of wisdom:

I am the owner of a used SOTA Sapphire, which uses lead shot to balance the subchassis. The original owner did not keep the unused shot so now I am wondering:

What is the total amount or weight of the lead supplied with the turntable originally? I have enough lead, I just don't know the right amount to start with. Any assistance would be sincerely appreciated.

Thanks to all for your participation. According to two different sources on the web, the leg bolts on the SOTA are 5/16-18. Mine is still in the shop but I will verify it when I get it back. Regards, hifigeezer
You need enough lead shot so that the sum of your armboard weight and the lead shot weight equals from 2 lbs., 15 oz. and 3 lbs.
In short, the combined weight of the armboard and lead shot should be very close to and not exceed 3 lbs.
The combined weight of the SOTA-supplied armboard and the lead shot supplied with my turntable was exactly 3 lbs.
The 3 lbs total weight is to control the resonant frequency of the suspension.
Once you have the proper amount of lead shot, then follow the SOTA setup instructions.
