Default Removing relay without damaging pcb (plated through holes)

On May 30, 4:44 am, wrote:
I have an old project where a relay is oddly stuck in a state with the
common rail connected to the normally open contact. I can only assume
that the two connections fused together during a high-current
transient. The relay breaks a connection between an audio amplifier
circuit and a subwoofer. I think my only choice is to replace the
relay. There is however a problem where the pins of the relay are
soldered to plated through-holes. This is making the relay nearly
impossible to remove without risking damaging the pcb. Does anyone
have any neat tricks to remove such a component safely?
Thanks


Carefully destroy the relay without damaging the circuit board so that
you have the stubs of the leads still sticking out from the PC board,
then solder to them. if you're lucky, there'll be enough leads exposed
so that you can just cut them and leave enough stub.
