I have the 309D and have'nt noticed the problem. It is difficult to set because the minutest change in the fine tuning wheel, seems to make big changes in weight, so you tend to overshoot the desired weight. I use a good but not uber expensive digital scale. Once set, it seems stable and certainly should be. If the arm is under gaurantee still, I would try and replace it. in general I find the Ortofon an excellent, well built arm.
VTF issues
Hello everyone,
I am having trouble with my tonearm vtf staying stable. It will fluctuate as much as a 1/2 gram just picking it up and setting it back on the meter. It never measures the same twice. I have 3 different vtf gauges. 2 digital and one Shure and they measure the same thing.
I believe it has to do with the adjustment knob on the tonearm. it is very sensitive. It can take up to 30 minutes to get the right reading. The tonearm is the Ortofon RS 212 D.
I just recently purchased the Lyra Kleos. It has a light vtf and the manufacture warns against over loading it. While listening last night the cart started bottoming out. When I measured the tracking force it had gained a full gram.
Is this sensitivity normal or could there be something wrong with the tonearm.
