This requires two turntables which run at an EXACT same speed (most modern 78-capable tt's will suffice)...and the patience needed to manipulate the two so that the records play EXACTLY simultaneously! (acquired through practice!). There is usually an audible difference in two takes...usually so obscure that only this direct comparison makes it evident! OTOH, I have a set of three alternate takes issued on a Harmony-group record...each of the three contains one audible mistake! I can only assume they tried three times to cut the tune...and when each attempt produced an error, they finally decide "Well, issue all three takes; we can always tell buyers that the "other version" doesn't contain the error!" Which, of course, it didn't...even if it contained a DIFFERENT error...?! Steven C. Barr
