Peter-E Posted January 15, 2020 Share Posted January 15, 2020 (edited) So I'm a newbie and it seems having trouble setting anti skate. As per the instruction for the VM95EN stylus my weight is set at 2 gms. The manual says set anti skate to the same on the dial. But I'm losing the right channel at times I read to set the stylus on a blank section of a record and see if it skates. It did, towards the outside edge. So I adjusted the anti skate till the stylus does not move on a stopped record (now at 1.5 approx). Bit it seems I am still getting channel drop outs. Have I set it right?

VanArn Posted January 15, 2020 Share Posted January 15, 2020 The use of a blank section of a vinyl disc is a an invalid method of setting anti skate. For a basic reason for this statement, consider that the stylus tip is a single point contact which will encounter different frictional drag forces in comparison to a stylus with two points contacting a 'V' shaped groove. There can be other reasons for the right channel dropping out such as intermittent connections, high bearing friction and possibly a worn out stylus Link to comment Share on other sites More sharing options...

I would think anti skate set not right would be a constant problem rather than drop out. 1 hour ago, Peter-E said: But I'm losing the right channel at times I would check cables and cartridge( small wires to headshell) properly connected to the arm ect.

VanArn Posted January 15, 2020 Share Posted January 15, 2020 So, exclude the worn stylus and add check that the overhang adjustment has been correctly set with a protractor. Is this an original Audio Technica cartridge that came with the turntable and what make of T.T. is it ? You may be justified in returning it to the store for testing.

aussievintage Posted January 15, 2020 Share Posted January 15, 2020 I have never heard a channel drop out because of anti-skate. I very much doubt that is the problem 1 Link to comment Share on other sites More sharing options...

I very much doubt that is the problem I emailed Audio Technica. they sent a link to a TT setup. The video included setting anti skate. I read a number of links in google that said it can cause drop out as the needle is aligned to the top side of the groove more than sitting in the middle touching both walls Edited January 15, 2020 by Peter-E Link to comment Share on other sites More sharing options...

I read a number of links in google that said it can cause drop out as the needle is aligned to the inside of the groove more than sitting in the middle touching both walls Sorry, but I still don't believe you ever hear a dropout because of it. At most, you might hear some minor mistracking in the form of sibilance or something. Not even on the cheapest record player that tracks badly and has no anti-skate have I ever heard one channel dropout, unless there was some other major problem. 1 Link to comment Share on other sites More sharing options...
andrewinbriz Posted January 15, 2020 Share Posted January 15, 2020 So you have intermittent channel drop-out? Does it always occur in a particular circumstance (eg same place on the record)? I strongly suspect it is not related to anti-skating setting. It might be theoretically possible, but in all my years I've never seen it result in a channel dropping out entirely. Any kind of troubleshooting has to be orderly. Even make a list and work thru it. Yes, check your cartridge wires, 1 Link to comment Share on other sites More sharing options...

Yes, check your cartridge wires, The most likely cause of a channel dropping out is indeed electrical wiring, or contacts. Link to comment Share on other sites More sharing options...

My protractor should arrive today If you have a removable headshell, remove it and clean the contacts. Same for the cartridge leads/connectors. Inspect them carefully. You might even need to tighten them, especially if they have been reused from a previous cartridge. Link to comment Share on other sites More sharing options...

andrewinbriz Posted January 16, 2020 Share Posted January 16, 2020 If you are removing the cartridge leads (to clean the pins/clips and then re-connect), be patient and careful. I use either tweezers or very small needle nose pliers, underneath a bright magnified light, to gently ease off the clips. Some tonearm wiring, even on more expensive than entry level decks, is absurdly fragile, so take your time and be gentle. Link to comment Share on other sites More sharing options...

Peter-E Posted January 16, 2020 Author Share Posted January 16, 2020 Hopefully the problem is now fixed. I've run 4 records through it and no drop channel I removed the headshell and checked wires. Removed and reseated Rebalanced and set antiskate and VT to 2gms. Also put phono on and plugged back into phono on the receiver. It was plugged into the CD as per instructions. So far so good. Thanks all for the help Link to comment Share on other sites More sharing options...

Sorry - don't quite understand what you're trying to say, Peter?? You had your phono cable plugged into the wrong input RCAs on your receiver? If so (it was plugged into the CD input) ... how come the instructions said to do this? Andy Link to comment Share on other sites More sharing options...
