The KAB battery strobe is the way to go, but the strobe disc you 'printed out' is only partially accurate. You really need to purchase the "Cardas Frequency Sweep and Burn-In Record. It has a set of various strobe speeds printed on the label. You should set your table speed with the stylus engaged into a record grove. Believe it or not the slight, minuscule drag from the diamond in the groove will create RPM loss, which may lead to unhappy listening sessions. Some people even run a bit of 'advance' on their tables, which is more pleasing to the brain for some odd reason.
