   Removing resin from a 49:1 sealed transf

   Hi All,   
      
   After I do not know how many years, I'm back here on the net :).    
   So back to the primary topic:   
   Recently I've purchased an 49:1 unun from a manufacturer, but I am not   
   satisfied with the performance of it (compared with another 49:1 transformer   
   the SWR is notably higher.    
   Therefore I plan to dissassemble it completely, but the main problem is that   
   the ferrite inside the box is sealed wit a resin. I would like to hear your   
   opinions or experience, how to safely remove the resin without   
   damaging/destroying the ferrite ?   
       
   Thank you
