Cardas Upgrade - Arm Balancing Problem


Hey guys, I just upgraded my RB300 arm wires to the Cardas wire set-up and installed a new cartridge on it all at the same time. The cartridge is the Goldring 1042.

When I balance the arm while the tracking is set to zero the arm floats all the way up. The counter weight (standard) is set all the way to the "front part" of the rear stub and the arm floats all the way up to its highest position.

Is the Goldring that light, or is the wire that much lighter than the standard wire? Did the guy who did the upgrade screw up some kind of bearing?

I agree with Zaiksman,a small bit of blue tak or equivalent will help but now you may need to focus on how well this combo can trace grooves.
I know what happened now guys. Ispoke to a few people, and what I found out is:

The guy who did the wire upgrade most likely did not set the tracking force to 3 before disassembling the arm. Therefore, the spring came out of position and was now not optimal. I brought it back to the same guy who did the upgrade in the first place and he removed the spring and set the weight using the counterweight, which is what he suggested to me in the first place.

Zaikesman, the spring in the arm will always add a little upforce, if you remove the spring the arm will not float regardless where the counterweight is or how light the cartridge is. I too did not know this. Origin live suggests setting the tracking force to 3 (which will act like there is no spring at all) and adjust the tracking force using just the counter weight. Somepeople say go one better and remove the spring completely as it adds resonance.

If anybody has any suggestions as to the accuracy of what I have wrote above, I would greatly appreciate it. TWL comes to mind, where are you.

I'm here, but I have to confess I didn't know the answer to your problem. When things are modified, I have no way of knowing what was done, or how it was done, so I could really be of no help. This is why I didn't respond to the thread.

It sounds like you've got it fixed now, so I am glad about that. I know it's a pain when the rig is not working.t
Well, you got me: I'm not an owner and evidently no expert about the Rega arm design (sounds like the same could be said for the set-up guy!). I guess from your description that you'll have to calibrate the VTF using an external guage. It's curious to me, given Rega's reputation for being zealous about rigidity, that their design can supposedly be improved upon (according to some) by eliminating a source of resonance.
