I have a uniden pc-78 that Im tring to repair the polarity was crossed with NO FUSE INLINE!!!! Why anyone would run any radio this way is beyond me but anyways the traces surprisingly were all ok but the 1969 final was so burnt it is cracked right down the center heres the problem im having where one of the legs for the transistor was soldered to the boar all the solder stayed on the leg and I cant get any solder to stick how is this done??

Getting solder to stick to a board that it completey came off

sounds like the trace has been fried off from where the leg of the transistor goes , look closely , you should see where it ends and goes , you can jump it to where the trace ends , if that's case , it's hard playing the guessing game without seeing it with my own eye's. If the trace is gone ? solder has nothing to stick to , you can also lightly scrape a covered trace with a exacto knife to bring up the copper side of the trace , then the solder will have something to stick to.(traces are like wire with there jackets on and they can be lightly striped as well ) I've seen radios fried where traces were burnt right off the boards , this is where jumpers come in to replace the fried traces.
tony,
solder a short piece of wire to the leg of the new transistor, and heat shrink tube it.
mount the transistor in place, solder on the two other legs, then solder the wire to the component lead closest to the trace that was damaged.
its simpler than i made it sound.LOL
