Isn't that Lsj74 Lsk170 acting as a buffer ? So what happens when you drive it with a 15v sine wave won't the Lsk74 be exceeding it's 25v drain to gate and gate to source rating and likely go poof !
In the thread "F4 Beast Builders" by 2 picoDumbs, he measured 5, only one on the most right side (photo 3) looks ok with my SIT. The chance to find a proper one cost more than buy a new SIT.
well, that's the reason to obtain a pair of SITs with lower Ugs 🙂
you can buy them , still greening how cheap they are , comparing to proper manly amplification devices

woody - same buffer used in F4; though with some care to save it when input signal ( by mistake ) goes through the roof
I use LSJ74 in F4 building with +/-32VDC, it looks like OK so far. I may have not driven the amp to 15VAC RMS.
gates cross connection with temperature/Current Positive component
Could we do this way?
is there any component or small circuit to increase the voltage cross it with increasing Ids/temperature?

you can always try with NTC, but good luck .......
you can wait some time, I'm going to publish my SissySIT R.3 relatively soon, then you'll see how I solved exactly that issue - using SIT and mosfet of any Ugs value

basics pretty much explained in LuDEF thread
same applies to SissySIT R.3 ........ and anything you can think of, using DEF OS
