We introduce a random matrix ensemble for bulk type-II superconductors in the mixed state and determine the single-particle excitation spectrum using random matrix theory. The results are compared with planar tunnel junction experiments in PbBi/Ge thin films. More low energy states appear than in the Abrikosov-Gor{close_quote}kov-Maki or Ginzburg-Landau descriptions, consistent with observations. {copyright} {ital 1996 The American Physical Society.}
