Well that is what I was thinking. I did not believe him this time since I have a good capacitance meter and I have checked the same capacitors new and then later after being pulled because I was curious to see if heat had affected them. I had to rob some 47uf's and 13uf's to use on a hot jobs and they were not altered at all. Quote Link to comment Share on other sites More sharing options...
lucky5115 Posted January 23, 2018 Share Posted January 23, 2018 Learned something new today. I was using a soldering gun on a crossover about 2 1/2 inches away from ferrite core inductor and saw a very faint orangeish spark travel from the coil to the gun tip; just one iota of a mili second. Upon further investigation, I noticed that the weller tip was real loose on one connection inside the gun. Not sure if that happened because it wasn't grounded properly, dunno. Checked inductor specs and all was well. Threw away the gun and purchased new iron. Quote Link to comment Share on other sites More sharing options...
pzannucci Posted January 23, 2018 Share Posted January 23, 2018 I have seen pc boards fail after exposure to a magnetic fields though I doubt anything that is being worked on in a speaker will be susceptible to damage from the magnetic field of a soldering iron.
