Hi... I just finished soldering all the components on my new F2624 board... And plugged it in without using a dim bulb tester. Surprise suprise... Would not come out of protection and saw a spark at the bottom of a transistor. The led kn the left side kf the board also shortly went on after a few minutes. I was also unable to adjust the dc offset. It stayed around 12v on f04 and f05. Sorry if I come of very uneducated. I an still learning. Should I replace all the power transistors and try again with a dim bulb tester?
