I have a Ct sounds 2k amplifier. I am trying to sort out issues in the power supply. The ps mosfets are shorted, a few gate resistors are out of spec and it appears that half of these small transistors are burned. I am having an issue identifying the transistors, I can see L6 stamped on a few of them, I think they are 2sc1623L6TP. Can anyone confirm? Also I can’t confirm the part #’s on the burned ones, any thoughts on how to figure those out?
