Hi, super new to this so apologize for the basic questions, but I am trying to repair a rare circuit board pictured bellow and have a few basic questions:
1- where can I find the transistor that says C2334 L14S ? I've found ones that say C2334 but than the second set of numbers are different, would that matter?
2- What is the part that is in round in the middle with the markings 2 6 1 I ? Is that a transformer? and where I can find that one?
3- Also as you can see in the second photo the traces are somewhat damaged and bare copper is showing and I'm having trouble soldering onto the bare copper and the solder does not seem to want to stick to it (I am using flux), is there a way to solder to the bare copper trace?
all help is much appreciated,
cheers
