We discuss stochastic Schrδdinger operators and Jacobi matrices with wave functions, taking values in C so there are 21 Lyaponov exponents 7i ^ ••• ̂ 7 i ^ 0 ^ y z + 1 ^ ••• ̂ y 2 ; = — yi Our results include the fact that if yx = 0 on a set positive measure, then V is deterministic and one that says that {£|exactly 2j y's are zero} is the essential support of the a.c. spectrum of multiplicity 2j.
