      72-455A - Audio Generator

      Overall: 4 out of 5

      Great Unit. We use 6 of them daily and just purchased 2 more for new tech benches. Highly recommended.

      Great audio generator, poor reliability

      Overall: 2 out of 5

      Mine keeps blowing the 100mA power fuse, near the power receptacle.

      bought this several years ago, used it a few times, after some time I blew the 100mA power fuse on the rear probably touching the output lead where I should have avoided.
