Aladdino Posted April 5 Share Posted April 5 (edited) I have a Heresy II that has been stored in a large metal box for 15 years. I use a Unison Research Unico P Amp and prior to hooking it up I want to know if I should maintain it, I also noticed one of the pins at the back broken, any idea how and what to do Edited April 5 by Aladdino 1 Quote Link to comment Share on other sites More sharing options...
Marvel Posted April 5 Share Posted April 5 Welcome to the forums. Do you mean one of the binding posts used to attach the speaker wire is broken? The Heresy II crossover came mounted to the rear terminal plate. The earliest had a round cup, while the later ones were rectangular.

CWOReilly Posted April 5 Share Posted April 5 If you need to replace the binding post replacements are easily found on Amazon. Do you know how to solder? 1 Quote Link to comment Share on other sites More sharing options...
Marvel Posted April 5 Share Posted April 5 Those are a little difficult, as the crossover is attached to the back of the terminal cup. Quote Link to comment Share on other sites More sharing options...

Marvel Posted April 10 Share Posted April 10 I removed the woofer first. Lay the cabinet on it's back when you remove the screws, it's heavy. You have to remove the connections from the woofer, tweeter and mid driver. Make sure you mark the connections. And take pictures. I used a cheap red fingernail polish when I removed mine to replace the caps. You will need a good solder sucker as well. You have to remove the 3 screws that mount the printed circuit board to the cup. Then remove the solder where the binding posts poke through the circuit board. (Red Arrows) It was a pain to do this as a small jumper from the post to the board kept falling out when the solder was heated up 1 Quote Link to comment Share on other sites More sharing options...
Marvel Posted April 10 Share Posted April 10 If you aren't comfortable doing it, find someone who is. I don't know if @Deang would do it for you, but you would have to ship it to him. Quote Link to comment Share on other sites More sharing options...
