Yes, this is a vary interesting subject, thanks for the enlightening post 
Paul. I have a quick question for Steve Conner, though: Steve has anyone 
yet figured out how to "self-resonate" a ISSTC magnifier? I tried base 
current feed-back to no avail. Definitely didn't pickup on the correct 
mode. In fact I couldn't get it to oscillate at all. I may revisit this 
sometime later...
