EMT 948 w/ 929 tonearm.


Maybe someone can help. I set the tone arm to specs @ 250 g. The eyelet is rite above the counterweight hole for the Anti skate. whether I connect the counter weight or not, most of my LPs skip. What am I doing wrong?

I have EMT 948 with 929 tonearm.

At first you need to check tonearm lift pad. It shouldn’t interfere to tonearm to go down and to the cartridge needle to reach record surface.

The second is a dynamic VTF setup. You need remove antiskating and set VTF spring scale to zero, then to setup counterweight to hold tonearm in zero balance. Tonearm should to balance like a mechanical scales and the needle should be on the level of record surface. When it is done you can setup VTF by set spring scale to 2.5g. Then double check VTF with electronic or mechanical scale. If VTF is not correct you need to adjust by VTF spring. VTF spring scale can be very inaccurate and I use it only for relative indication.

After VTF is done you can add antiskating.

@lohanimal, I do have 948/929 instruction manuals.

@lewm, The height is set to factory @ 35mm & there's plenty of clearance above the cue lever. Now I couldn't tell you if the wires are obstructed.

@alexberger, I just re-balanced the arm as you directed. Had to lower the arm little. I think that was it! Thank you Gents. Dan

Please forgive me for appearing to beat what should already be a dead horse, but how did lowering the tonearm, presumably at its pivot, fix the problem of skipping?
