   Removing resin from sealed 49:1 unun box

   Hi All,   
      
   After I do not know how many years, I'm back on FidoNet   
   So, back to the primary topic:   
   Recently I've purchased a 49:1 unun from a manufacturer, but I am not satisfied   
   of it's performance (compared with another 49:1 transformer, the SWR is notably   
   higher). Therefore I plan to dissassemble it completely and use the ferrite for   
   another project, but the main problem is that the ferrite inside the box is sea   
   led with a resin. I would like to hear your opinions or experience, how to safe   
   ly remove the resin without damaging/destroying the ferrite ?
