Helikon run-in groove problem.....


OK...I just spent 2 hours with a very knowledgeable technician trying to figure out why my new (2 months old) helikon (regular) runs in on the lead in groove on some records. My arm is a VPI 10.5 and the tech is quite good at set up and VTA etc. We tried playing with the tonearm cable on the VPI (this is the cable conected to arm tube and the rear arm conection and is also used for anti-skate). We checked the weight,VTA, and still on some records (yes some older Mer's) even newer records..it runs in for a few revolutions or gooves. It is very annoying but does not happen at the end of the record and it plays quit nicely overall. This should be a good question for Helikon/VPI arm 'goners.

Thanks for your help!

Eureka!!!!! Thanks Scott, I think I found the problem. After getting your post and e-mail I checked the level of my Aries and it was right on....completely level. Then I checked the arm rest and arm lift. I carefully viewed the decent of the arm after I released the lift and "low and behold" the arm went down smoothly AND THE STOPPED....for a fraction of a second, THEN continued it's decent. This must be the cause of the run in at the beginning of the record. Now I have to figure why and how I can correct this faulty arm rest.
Thanks again Scott for your help and I hope this may help any other other there with a similar problem.
Thanks...SDC....yes you described my problem exactly! I also have a Micro-Benz M-2 cartridge in another arm tube that does NOT have this problem. You may have hit on the problem.....I was wondering if it might have been a problem with the Helikon? Don't think so, cause it sounds quite good when it is "into" the record. I will give it a try!
I just wanted to keep you all posted as to my progress with this problem............
Well here I am, red-faced, and STILL with the problem unfixed!
I was centain it was the arm lift that was causing the problem. I even viewed the arm semi-pausing on decent. So yesterday, my tech friend and I changed the arm lift to a brand new one and tried it out. Some records fine.....some not so!! It almost seems as though the Hilikon cartridge needs to sit in the lead-in groove just right and if it doesn't it skips out. Does this make sense? Anyway I have tried to lower the cartridge myself by hand and this sometimes causes the cartridge to skip in........then other times (if I hit the lead-in just right-usually closer to the actual record groove) it catches the groove just right.
Now I'm wondering if it is the cartridge???? It works and sound fine when playing a record??
I am calling the cartridge dealer to see if he has heard any problems like this in the past. I hope to resolve this and keep you all posted.
I want to get back to you all on this subject and close it out...........the culprit was the anti-skating. The cable between the arm block and the arm needs to be played with to get the proper anti-skate. I played, it work.......

P.S. I also changed the arm lift but the problem still remained untill I continued to adjust the cable.
Hope this helps!
