Headshell Shims - $159
These are problem solvers for VTA adjustment range issues as well as for experimenting with adding mass.
These shim kits are sold in sets of three.
Everyone should have a set in their toolkit.
When you need the right one, and it's a Saturday evening, you don't want to wait for the Postman (or worse - the next production run).
Two of the shims are for mass tuning.
- One is made from 7075 aerospace grade aluminum and weighs 4 grams.
- The hardened brass one on the right weighs 8.25 grams
The third one is the real problem solver. It's also made from 7075 aluminum but it has a 1.5 degree angle. It weighs 2.5 grams.
During setups, we've encountered situations where a tonearm adjustment runs out of range when setting the VTA.
- The 1.5 degree angle has the effect of raising or lowering the VTA pillar by approximately 6.4mm on a 9" tonearm. You can increase or decrease the SRA, depending on which way you orient it.
- You can use the angled shim in combination with either of the two "flat" shims"
We first ran into this problem with a cartridge requiring "low" bearing post height on a Kuzma 4Point-9.
