Hmm, never heard of any, and I'm a member of the Yiddish Artists and Friends Actors' Club here in New York. Perhaps prestidigitators were cowed by the "No dogs or magicians" sign posted prominently at the door...
Joseph Buloff (best known as the original Ali Hakim, the Persian Peddler in "Oklahoma") was using a few small effects to liven up his production of _Yoshke Muzikant: Der Zinger fun zayn troyer_ (The Singer of His Sorrows) when Morris Schwartz brought him over to replace Paul Muni in 1926. And Susan Burstyn, daughter of Peysakhke Burstyn and Lillian Lux, used to do some vent work in Yiddish.
Still, not quite what you're looking for. Nonetheless, there must have been, if not on Second Avenue, perhaps in the old country: I. L. Peretz wrote the story _Der Kuntsnmakher_ (The Magician), in which Elijah appears in town as a traveling Yiddish speaking magician; there is also Isaac Bashevis Singer's novel _Der Kuntsnmakher fun Lublin_ (The Magician of Lublin) about a magician who is most definitely not a saint.
I'll ask around, but you might also try signing up for the Yiddish theater and vaudeville listserve on jewishgen.org, information at: http://www.jewishgen.org/InfoFiles/ytheater.txt
