    I didn't want to advertise specific brands but it's not a secret. I use Kemet and Nichicon. Both brands are described in forums as good quality. It is what I could get from Mouser in this case. I also deliberately did not use Genteq or similar (cans of oil) because I wanted to stay close to the type recommendation of Klipsch. I'm all about the principle at this stage. The orignal Klipsch certified capacitors cost me over 220€ until they are in Germany because shipping, customs and VAT are very high. That's why I wanted to try first.

    @KT88, I'm very inspired by this post. However, I'm having trouble locating these capacitors. I need 2.2uf, 8uf, and 30uf for my Type AL network. Can you please help with providing links to purchasing these types of caps by Nichicon and Kemet?

    Leave the old leads in place and as much of them as you can. Then take the new cap and by eyeball cut one ends lead and put a 180 degree bend in it with enough past the bend to bend it tightly over the one lead sticking up. Then do the same at the other end and the trick here is to keep the trimmed and bent new cap leads short enough that you can snug it down into the spot where the old hot melt glue was. It makes kind of a cradle for the new cap to sit in. You are soldering close to the capacitor so you want to get on and off quickly to keep heat input low. If you are new to soldering practice first before you do this. If you can wait a week or two I have been thinking about making a video on  doing this and posting it on my old CAD design channel on Youtube.

      Word of caution on removing old caps. Do so as gently as you can. Some of those are really stuck on there and you do not want to damage the PC board,

     Poly caps have no polarity.

     

    Thank you. So just to confirm - I will be soldering the old and the new leads together, correct? This does not interfere with the connection in any way? And the 100v cap that comes with the Bob Crite kit (I know you used a different Audyn cap in your photo)  is also a poly cap, right? 

     

    I'm decent when it comes to soldering just have limited experience working on pc boards. I've done minor replacement part repairs on vintage receivers under someone's direction. I am def. taking my time on this and being careful not to damage any parts. Thank you very much for your help.

    Can someone help me with this. I'm waiting on my new crossover replacement kit to arrive. I just took out the crossover from one of my speakers in preparation. How can I remove the old dry glue they used on top of the plastic snap in screws that hold the two levels together? I don't want to break off the tops of the screws in the process. Also, is there a trick to inserting the crossover back into the speaker enclosure? I tried practicing just now and could not get it back in. Thank you in advance.
