you may build your own gauge model by using some stiff paper. do place one piece of flat stiff paper on the record and fix another piece of paper (use glue) on one half side of the "record paper". Fold it upwards, so it shows to the tonearm.Draw parallel lines to the tonearm on the upper part of the paper. When you place the tonearm in front of that gauge while the needle is in the groove you see your VTA position.
