Hi guys.
A while ago i run across this document which apparently tells how to wire mosfets in series to get higher voltages (pg 10-14). This is the only schematic i found so far that is actually working. The problem is that i can't make more than 3 mosfets work, when i add a fourth ( with the same circuitry) it remains OFF no matter what. I tried different resistor values. At first i though that if R2 has 2ohms and R3 20ohms that the next should be 200ohms. When it didn't work i tried 20,50 and 1k but with no luck. Can you please tell me what i did wrong?
Thank you.
