   I bought a pair of KT120's from The TubeDepot a few weeks   
   back just   
   for the heck of it.  After about 24hrs operation one of the   
   filaments   
   opened up (really).  I pulled the tube and checked it with   
   an Ohm   
   meter and noticed that when I move the tube the resistance   
   changed.  I   
   took a soldering iron to the filament pins for a few seconds   
   and that   
   seemed to fix it.  About 24hrs operation after that it   
   happen again so   
   I heated the pins up a second time.  So far them seem to be   
   working   
   but quality control seems to be an issue.  Aside from that,   
   they do   
   really sound good with a lot of top end...   
      
   *** Aha. I was wondering which end of the valve they'd   
   extended.
