  Jon Soderberg (who was with Threshold at the time and does Threshold repairs) attributes the design of the T series to Mikael Bladilaius, Mike Jaynes and Wayne Coburn. You might want to contact Mr. Soderberg and see if he can help you out. His contact information is available on his web site at http://www.rsvlonline.net/vintageamp/ .

  Good luck!

    Steve:

    THANK YOU! I called Soderberg and he provided some invaluable information, both on thermal runaway and on IGBT design in general.

    FYI, Bladilaius was the primary designer of the IGBT amps.
