So if you have 36V at the drain of Q3, use RW3A to set 18V at the drain of Q7. ••• More options Share couguarek Member Joined 2008 cougarsaudio.pl 2017-03-08 7:59 pm #43 2017-03-08 7:59 pm #43 Thanks I measured voltages and need to do some adjustments... ••• More options Share Prev 1 2 3 First Prev 3 of 3 Go to page Go Show hidden low quality content Status This old topic is closed.
