Rega RB300 Troubleshooting

I recently upgraded my RB300 tonearm with the incognito rewire kit and have learned from experience that it would have been better to have this done by a professional (especially since I've just voided the warranty). It was extremely difficult removing the rubber boot that housed the cartridge leads especially since the instructions said to push it INTO the arm tube!! What I ended up doing was removing a small, critical screw from the tracking force adjustment knob by mistake that I can no longer screw back into place.

Basically, my question is what are my options? I have no idea how to get the screw back in and wind the spindle back to it's original position. The knob was set to 3 when I removed the screw. Other than this, the upgrade went smoothly (even the soldering).

Any help greatly appreciated!

Hitman, have you weighed the tonearm/cartridge with a VTF guage? I'm guessing it's at 3 grams or higher but its a start. You already know this but it sounds like its critical to get the mechanical VTF on the arm dialed back. Why won't the screw go back in? Is there some sort of threaded piece inside the VTF knob you could manually move with a tool?

Are you talking about the spring inside the VTF knob? If you are trying to get it back to where it was with the proper gram calibration, you would most likely need to send it back to Rega.

If it were me, I wouldn't care. I pulled that spring out years ago because it rattles. I just use the counter weight to set VTF and it works beautifully. How does the new wire sound? Was it worth it?

My tt came with a rewired RB300 arm and when I set it up I could not get the VTF adjuster to do anything. So I used a scale (which I think is better than using the adjuster).

I got ahold of the seller and was told that the spring was removed to reduce vibration. That was six months ago and I just keep using the scale to set VTF no problem.
