yet another KAB mod question


Is the threaded clamp worth the 100 dollar price increase over the non-threaded model?--Cheers

Is anyone bothered by the fact that the fluid damper blocks the indicator for the VTA?

I am, but I've compensated.

I wish the indicator was not blocked, and I wish the fact that it was blocked had been mentioned somewhere before I bought it so I could have made the decision with all the facts on the table.

However, in retrospect I'd probably buy the damper again despite the design problem.
I typically set the VTA by sight (tone arm parallel to the record) and by sound, so the I don't really need the indicator. I agree with Tvad that the benefit is worth the minor inconvenience.
If you look - you'll find that the VTA reading on the collar at the arm lift lever is exactly 2.5mm (I think... I'm not at home to check the exact amount) higher than the actual VTA setting.

In other words - if you align 4.5 with the leading edge of the opening the silver arm lift lever comes through on the arm, the VTA will be set at 2mm.

I'll double check the numbers when I get home tonight - but I'm pretty sure it's a difference of 2.5mm.

I use a similar system in which I set the VTA to where the tonearm is level and then use the left edge of the fluid damper trough as the marker for the VTA numerical reading. From there, VTA can be adjusted up or down and you have a physical indicator for the reading. Essentially, it's the same as reading the VTA according to the original Technics hash mark, but the value is higher. I've never bothered figuring the numerical offset because I dial in VTA according to ear anyway.

Vinyladdict's solution seems very good, and a more precise version of my method.
I installed the silicone damper (blue) on my Tech deck in my main rig. Also picked up that ugly-ass KAB rubber record clamp, but it works. Kevin, if you read this, you need to upgrade that syringe, it is a POS. And please put a note on the install instructions to let the silicone acclimate to room temperature before installing. It will help the cause with that useless syringe. Also, I was storing the clamp on my BB slab, it stained the damn finish, and it won't come out.

Here is a link to my system...
