Glad you like the KAB but take it a step farther, you are not as perfect as you think you are.
You say you say you tweeked it and then played a record. A more accurate way, Put a record on the platter, then put the KAB strobe disk on the record, and your record weight/clamp also. Now your TT motor is pulling a bit more weight and running a bit slower, readjust strobe.
and a bit farther, also place the tonearm on the outer edge of the record, TT motor now has the added drag and weight of the tonearm which will also slow it down, readjust again.
All the exra weight and drag is there and should be considered when setting the TT speed.
PS, keep a spare battery on hand, Murphy`s Law: the battery will fail when you have guests and need to set TT speed.
