    Identifying caps on an old Zoom 9000

    Hello!

    I have two projects on my work bench. One is a friends dead JBL Xtreme speaker with a blown voltage regulator and corresponding bulged and shorted cap. That cap has clear markings so I know what replacement I need for it.

    The other project however is a whole different deal. It's a Zoom 9000 guitar effect from the 90th that has developed a devil hound howl when there is no input from the guitar. I'm guessing caps problem. So, since I don't really use this effect anymore I thought it would be a perfect project to learn on.

    I have studied the board and found several different caps on it. Some have markings that I can understand, but some I have not been able to decode even after founding the "cap decode chart".

    I'm guessing that this is a question that many of you are bored of...but would it be possible to get some help to identify the caps I need?

    I have marked the caps in my picture with colors. This is what I have been able to read of the caps, and the ones I think I have been able to identify the specs on in cursive.

    Orange, brown, blue and white I've have not been able to decode.

    I'm considering buying a set of caps from Amazon, so it would be great to confirm that all the caps I need is in the kit before I pull the trigger.

    Thank you so much for your help!

    Oh...I just realised that there is a sticky thread where I should have posted this question. Sorry for that. Maybe admin can move it there? I don't think I can do it and I don't want to double post.

        it's right there,
        top line is the uf and middle line is the voltage

          So it's that simple? 😃 It's those letters that are confusing...especially since the "cap decode chart" is letter---->voltage.

          So in my case the 50S is just 50V, 15A is 15V and 6S is 6V? Makes one wonder why the manufacturers doesn't just stamp that instead. 😁

            not always,
            but if the numbers are known values it's probably right.
            15 wont be a voltage, 10 or 16 could be.

            if you really want to look them up then try here:
