[Amps] henry 8k roller coil issue

[Gary Smith]

Seen one of those roller wheels out of a 5k model that had spiked edges that looked as if they could pierce paper. Owner and I guessed (probably correct) that this was due to arcing that occurred while amp was *WAY* out of tune
Owner had to find a small job machine shop and had one made to his specs. 
Want to recall that new item was made so the outsides of the wheel were about half way past the diameter of the coil.
Maybe you ask someone who has a Henry to peek inside to see where the edge of the wheel stops at?
Another idea: contact "Radio Dan." I have heard he has parts for some of the Henry amps. His last known url is: www.radiodan.com 
Best of luck to you on this,
73,

  I have a Henry 8k ampl that has a bad "contactor wheel" on the "edgewound"
  loading coil.   I have pictures of the problem with the contactor "wheel" but
  I am not allowed to post them on this reflector (unfortunately!!)   If anyone has knowledge of the 8k construction and thinks they mite have some ideas please email me and I will send some pics.

  Henry abruptly went out of the vacuum "tube" ampl biz last Dec.  leaving the installed base high and dry ..... help de Bob W7GG
