    • "Great audio generator, poor reliability" by richjohnson on 3/8/2014
      Overall: 2 out of 5
      Value:
      Quality:

      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.
