Hello everyone,
I purchased a pair of S75's about six months ago and have more than happy with them. Upon further inspection however, I noticed that one of the midrange speakers was not working. Set up with a 5.1 system it was difficult to hear the absence unless you were close to the speaker so it didn't bother me. I recently got a moment to open it up in attempt to locate the culprit. Let's just say it was quite obvious (see photos below). After opening it up, the woofer wire fell apart. It amazes me that any sound came out of any of the 4 speakers. After a few hours of google image searching, on the spectrum of "light toast" to "your toaster melted", I fell as though I landed the latter. I opened the other speaker for comparison and to make sure it wasn't in need of some major TLC as well (pictured below). Thankfully it looks brand new. I will likely order two of all replacement parts and repair both crossovers to the same specifications for continuity.
My question is in regard to the inductors. I was originally going to ask about specifications for the capacitors and resistors but was able to locate a schematic with the values (included below). The schematic does leave some information out about the inductors. As you can see in the photos, I do not think it is a good idea to replace everything and leave the charred inductors in there.
The schematics state that the most heavily charred inductor has a specification of 0.26mH and has a ferrite core. Looking primarily on Parts Express but also some google searches, 0.26mH inductors are difficult to find. 0.25mH and 0.27mH inductors are plentiful. I also noticed that with differences in wire gauge comes differences in Ohms. Is there a way to tell, or does anyone know what gauge wire these inductors have or their original Ohm rating? Would using a 0.25 or 0.27mH inductor make much of a difference?
If the seemingly infamous "Martin (Dillen)" or someone similar stumbles upon this, they are Type 6313.
Any help is greatly appreciated.
