Re: [TCML] suggestions for nst cracks in potting



Hi Robert,

You can of course repot if desired, but it's quite the chore. I recommend doing this outdoors as the fumes are quite stinky. I used was as you are probably aware. It's not the greatest potting compound, although it does make future repairs a little easier and faster (still a pain in the butt). I think if I were once again to repot that NST (and it is in failure mode this past year), I would probably just put in under oil.

Take care,
Bart

   Have a couple of nsts12/60 and 15/60. Opened the top and there are fissiors and cracks in tar. Probably due to the tar drying out over time and shrinking.  these cracks seem to be an easy path for arcing across windings internaly. Read Barts and others experience about repotting, etc.  Im interested in getting the most life out of them as they don't grow on trees!$!  Heating them up in a rod oven seems like the simplest .  Any more suggestions would be appreciated.
  PS
 Have built nice t-filter for the 15k that will be used on new TC.
