The big difference is in the 'totem pole' driver and output
stage, that allows higher voltage and power using the
same types of driver and output devices.
Without some judicious tweaking of certain part values,
your transformer's output voltage is going to be
dangerously high for the 'regular' Leach design. How
lucky do you feel? The key phrase here is "Safe Operating
Area", which is an important parameter of power transistor
ratings. Higher operating voltage pushes the devices
very close to their limits.

Hi Damon,
Ive read the build notes on Jens website and I do exceed the SOA for 6 devices. If the impedance was to dip to under 4 ohms at certain frequencies, it could all blow
Im thinkink I might have to go regulalted to loose 10 volts or so. Any one got a good easy regulator?
