CS400i Crossover details

Does anyone have schematic for a cs400i? In the vintage section a lot of schematics are posted and the cs400 is there, but no "i" version. I think there were some small differences. I am looking for specifics for a recap. I will take mine apart to check if need be, but that involves moving a lot of stuff. I was hoping someone has the details. Thanks for reading.

    Was looking to change out caps for mine back in 2013 but never got around to it. Don't have a schematic but did exploratory surgery and believe I took pics of the caps...unfortunately, can't find them. Did find a file titled "XO Cap Values" in a CS400i folder. Not sure where I got the values or if they are correct but for what it's worth?

    34uF 50V 5%
    200uF 50V 5%
    9uF 100V 5%

    I don't remember if there are any differences. However, the CS400 has to be about the easiest speaker ever to take apart. The plastic frame hold the compressed fit speakers in place. I think its like a 5 mm hex needed, Probably 5 min tops! If you have to do it 2-3 times its not a big deal.

  • Thanks all for your responses! What I can see in that picture backs up the specs JayCee posted. I should just open my speaker up. I was just trying to avoid moving my who entertainment unit. Unfortunately my 400 does not quite fit out the front. Its too tall by 1/2 an inch. I will move everything and put stuff on order this weekend. I'll post more details here in case someone is looking for this information in the future.

    If you have to do a cap swap, you'll have to do this anyway. Just run without it until you get everything replaced. Then you only have to move it twice.

  • We rescued one and then another. We really love sharing our house with them. Less so when they are eating things, which doesn't happen all that often. Generally they are fine alone with each other.

  • I guess destroyed by chewing is a more accurate description. I dont think anything substantial was consumed, but who really knows.

    Well with these kind of dogs it's always a possibility things go south in a massive way. Most times male and female are good but two of the same s ex and it can just take a look.

    I raised two brothers from my female they grew up all their lives together never apart. One day at 2yrs old they looked at each other acossed the room at each other and it was on. From that day on they could no longer be together at all.

    I'm sure I'm not saying anything you do not already know.

    Good looking dogs
  • we brought this pair together when both were around 3. it took most of the first year for them to fully bind with each other. the first year involved more than one trip to the vet for stitches. Eventually patience won the day and they are now fine around each other. There were a few scary moments as they are big strong dogs.

    I finally got around to opening my CS400i and I can confirm that the values JayCee posted above are correct. Now I will have to try to track the correct values down. A little quick searching shows that some of these values are not easy to find.
