yesterday i found my class e sstc in a box and decided:
i´ll upgrade it ^^
and so i took a irfp450, some capacitors laying arround, a air inductor and a ferrit core (become the 7:3 gdt)
and worked almost 30 min on it xD
that´s what happend:
the signal is created by a cristal oscilaltor, then amplified by a bc547, then a bd139/140 driver stage driving a 7:7 gdt.
the gdt drives a irf840 mosfet in class e configuration which drives the second 7:3 gdt.
the signal from this on is connected to the gate of the irfp450 (also class e) which power the 4 turns primary.
the hole setup:
the irfp450 class e stage:
and a vid with lower voltage then on the pictures
