[pianotech] Dampp-Chaser component issues

Hi Alan.

What if you got an electrician to shorten the lead and re-attach the plug close to the Dampp-Chaser unit. You could then use an extension cord running from your power source to the new plug on the Dampp-Chaser, giving the option of disconnecting at the piano before moving the pianos. If leads are still getting damaged, the only replacement needed would be an extension cord, which is a lot cheaper than a new Dampp-Chaser.

Hope this helps.

  We have come up against two problems with the components of our Dampp-Chaser systems.   


  One is damage to the power cords by stage dollies when the piano is mounted on one and gets moved around at all.  The problem is that the ac power cords get run over by the dollies. Over time, the insulation of the cords become worn enough that the copper wire itself becomes exposed or, worse yet, the cords become severed. Our school’s safety policy prohibits taping of exposed wire or splicing and taping a severed cord, and it doesn’t look like there is a consumer-feasible way to replace the cord, requiring replacement of the humidistat (which is lots of $$$, considering it is really a cord-related problem). 

  Does anyone know of something in which the power cords can be encased, so as to leave them flexible, yet make them more impervious to the effects of being run over by the wheels of the stage dollies?  Or is there a way to replace the power cord without “compromising” the housing of the humidistat?  


  The other problem is what to do when the rivet that holds the low-water warning light probe in place gives up the ghost and no longer does it's job.  Has anyone else out there run into this and developed a reliable fix? 

  Thanks,

  Alan Eder
