      Jim,
       
      Would you be willing to set aside that other 10H at 200 ma choke? There is a nice looking SE KT88 project I think those matching trannys would work for assuming I pad down B+ a little though the extra 25-30 volts really won't hurt the KT88 I don't think. Here is the link:

      Do you think that 100ma is enough to run a SE kt88?
       
      Thanks,
       
      Blair
