terrible, I would recommend not using the anti skate at all, just to hear what that sounds like. Then, to set the anti skate, I would use a laser disc.
A pitch too High!
Recently, I damaged the V2 MM cartridge of Clearaudio Concept Wood turntable, so had it changed with a Grado Prestige Blue. The VTF for V2 is 2.2g while Grado blue stands at 1.5g. I took someone’s help to fix this. He even made azimuth adjustments and it sounded fine. But I soon realised that the sound had become thinner, voice being the primary indicator and just before the stylus landed on the record, it skipped back a bit then hit the record. Sometimes the tonearm would skip all the way out of the record, backwards. I called the guy back, and he felt the VTF should be fixed to around 2g to avoid the backward skip. He did so and that problem was licked and it seemed the voice thinning issue had also vanished. But last night, I put on the first pressing of Aretha Franklin Amazing Grace, and all along I found her pitch way higher, it was all too high pitched and uncomfortable. Seemed the bass had gone missing a little. On my Boulder 866, I could immediately hear the difference when the track was played through Roon. It was not as high pitched, thin as it sounded on analogue. I intend to call the guy again but wanted to know from experts here as to what the issue could be.

@terrible , No! You use your tonearm lift an gently lower the arm in between grooves in the run out section and watch which direction the tonearm drifts. The stylus is not in the groove! It will find a groove in a couple of seconds but that is more than enough time to determine what the arm is going to do. It should drift slowly, very slowly towards the spindle. If you have a record with a blank side like The Lumineers Cleopatra you can use that. This is the method Frank Schroder and Peter Ledermann recommend and it really is quite simple. |
@mijostyn I think I understand you. I'll record and put it up here soon. |
@goofyfoot How do you use the laser disc to test anti-skate? Is there a video or something out there? I could not find any. |
@terrible , Laser discs are smooth, no grooves. You can use them like a blank record. Laser discs are long out of production. Warning! Many people believe in adjusting Their antiskating so that the tonearm stays still on the blank record. This overestimates antiskating. The arm has to drift slowly towards the center towards the end of the record. This is not a vitally critical adjustment like VTF. There is no exact value because the amount of pull on the tonearm varies with multiple factors. It is a ball park adjustment. |
