Flux flow resistivity rho/sub f/ and upper critical field H/sub c//sub 2/ of ideal type II amorphous bulk superconductors Zr/sub 3/Ni and Zr/sub 3/Rh on both as-quenched and thermally relaxed states have been studied. It is found that thermal annealing does not change the temperature dependence of H/sub c//sub 2/ in homogeneous superconductors. The temperature and field dependence of rho/sub f/ in all samples studied exhibits a universal scaling relation of the form rho/sub f//rho/sub n/ = f(h,t), where rho/sub n/ is the normal state resistivity, and h and t are reduced field and reduced temperature, respectively. The results are compared with predictions of the time-dependent microscopic theories for bulk superconductors in the dirty limit. In the low-field region (H<
