I wonder why the AM antiskate tracks are so low in level. 4.8db lower than the lowest antiskate track on the Ortofon record ( 50um).
certainly no match to track AM33 V2 antiskate track... Maybe there is is an objective I do not know of
Record in CoolEditPro(adobe audition) and Analyse the 440hz part. /or Parks audio Puffin or just look at the mV values in the top if the AM plot and convert to db, or use a mv meter pun your output of amp etc
Or VA Visual analyser or analyse recording in REW/ import audio
