kg4guy Posted November 24, 2007 Share Posted November 24, 2007 I have a pair of Heresy 11's with the square crossover and having a problem getting crossover board off the two terminal posts to replace the other caps I was able to get the 68 in and one 1.5 but getting others in without removing the board seems very difficult ??

BEC Posted November 24, 2007 Share Posted November 24, 2007 You have to remove the three phillips screws you see in this picture. Then unsolder the wires that are wrapped around the two terminals. Clean the remaining solder off of the terminals using a solder sucker or solder wicking braid and then remove the two nuts holding the circuit board on the terminals. The circuit board will then lift off the terminals. Bob Crites Quote Link to comment Share on other sites More sharing options...
kg4guy Posted November 24, 2007 Author Share Posted November 24, 2007 I was trying to unsolder the wires around the the terminals did not seem to want to unsolder I will try again also what is a solder sucker or solder wicking?Thanks Quote Link to comment Share on other sites More sharing options...
BEC Posted November 24, 2007 Share Posted November 24, 2007 The solder sucker is a spring loaded plunger that creates a vacuum when the plunger retracts. Solder wick is flux coated copper braid that soaks up molten solder to remove it. Both should be available at a Radio Shack or other electronics supply place.

kg4guy Posted November 24, 2007 Author Share Posted November 24, 2007 Thanks again Bob I went to Radio Shack and got items. The solder on the terminals did not want to turn into liquid it was more looking like clumps ,do I just need to apply heat longer? Quote Link to comment Share on other sites More sharing options...
BEC Posted November 24, 2007 Share Posted November 24, 2007 Sounds like you need a higher wattage soldering iron or you are not having your iron properly tinned to transfer heat quickly. If you are having to apply heat longer than for a few seconds, you will be getting close to melting the plastic that the terminal is in contact with or damaging the circuit board. Practice your soldering on something that you won't have to worry about damaging before a project like rebuilding a crossover.

Marvel Posted November 24, 2007 Share Posted November 24, 2007 This may sound weird, but do you happen to have any solder flux? Or solder with a high rosin content? Put some flux on the joint and then heat it up again. It can do wonders. Or add new, clean solder to the joint and then remove it all.
