The stylus when placed on a blank test band when rotating will imitate a stylus cutter. No amplification required. A cutter with no signal would produce a groove with no modulation, the same as the silent gaps between tracks.
You initiated all this denial of any (quite normal) scarring made by a stylus as observed by the OP, and clearly visible on his test record. He clearly replied saying the tracking force was correct. Your suggestion that there should be a wide “study” to quantify this is plain bonkers. To further suggest my input was a “pronouncement” was purely an intended sarcastic and uncalled for remark. Giving also a “Hint” on something you have never experimented with or observed yourself is completely unfounded and unsound. You obviously can’t tolerate being corrected.
Try the test yourself, and then criticise. If you don’t know anything for sure, l suggest politely to belt up.
