Thank you for your responses and yes that makes sense. I wasn't thinking about how mosfets behave when overheated. I checked all the solder joints and ohmed out Q8 - Q11, T1 and L14 to see they had continuity where they were supposed to have it on the circuit board. I suspect I have either wound T1 incorrectly or I have scraped some enamel off the wire and it's shorting to an adjacent wire or the core. I am considering rewinding it with fresh wire if I can get it off the board without damaging it. I'm open to alternate suggestions. ?
