yes I mean POWER JFETS such as Lovoltech LU1014D, and the R100, R550, R085 semisouth parts etc. for output and cascode device. these of course require a bit of patent infringement to use 'balanced' :D SuSy, that is unless in a circlotron, which i'm also playing around with at the moment.
also lateral and japanese mosfets (2SK1529/J200 and 2SK1530/J201)
hey I didnt dig up the thread, just noticed it on the first page and posted an opinion in it :P
