    digitalstream dtx9950/15-150 bad "jl" caps.

    this unit less than a year old. it started puzzling even on strong signals and had noise in the rf out since new.
    a neighbor bought it with taxpayers money via one of those $40 cards.
    i expect there will be a ton of these dieing off soon.
    too bad there was no minimum durability standard required for coupon eligible units!

    I guess you are right about the durability standard for coupon eligible units, especially in the electrolytics department.
    My first choice in quality Japanese electrolytics is Nippon Chemi-Con, which has been in business since 1931... the quality of electronics is dependent on the quality of the electrolytics.

      I bought the all digital version (no analog pass through) last year around May and it had Daewoo caps on the PSU.

      I replaced them all with Panasonics.

      I couldn't resist opening the unit even though it was working good thing I did.

      A very simple switcher utilizing a garden variety TOP IC.

      Out of all the converter OSDs I liked this one the most.

      I bought it for the hell of it with a coupon just to see what these boxes were all about.

      I'm sure the new boxes still have that annoying ssssssing in one of the channels when receiving Dolby audio right?

      Elements of the past and the future combining to make something not quite as good as either.

        Seasonic B12 BC-550 – barely 2 years old and with BAD CAPS already!
        by momaka
        I know I've been a little scarce lately (like the last 2-3 years), but I'm still here and still doing my thing with fixing PSUs.

        For today's considerations, I have a Seasonic B12 BC-550 [A551bcafh] 550 Watt ATX power supply for you (click on links for full size images).

        It's a modern ATX unit with fixed (non-modular) cables and an 80-plus bronze certificate. Here's the label:

        Heathkit IO-4205 Power Supply Caps
        by eryjus
        Hello,

        First, I am a complete noob with high voltage stuff. I'm learning, but I need help by someone looking over my shoulder.

        I recently came into posession of a Heathkit IO-4205 5MHz Dual Trace Oscilloscope. The documentation is copyright 1978. I'm told it works.

        I opened it up to check the caps before I applied power, and found the following black caps and wanted to know what they were. They are on the power supply board. I was able to read the name and model and came up with, "Nytronics 162J-1, 0.1uF, 20% tolerance, 2000VDC."
        ...

        Identifying caps on an old Zoom 9000
        by Paxman_Swede
        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...

        Help with switching power supply caps
        by captain150
        I'm trying to repair two old VCRs, they both have bad caps. One has leaky ones, the other would barely run until I subbed in some caps from another power supply I had laying around (though they are the wrong values). This vcr works for an hour or two, but then the power supply starts whining and the picture gets lines in it. I didn't replace all the secondary caps, so another voltage might still be problematic, or the values I used are too far off.
        I've been on mouser and digikey but the options are a bit overwhelming. I just need some new ones that will work. They don't need to be top quality,...

        Gigabyte GA-6OXT :: caps question
        by Foetuss
        Good evening

        I recently aquired a rev 1.1 Gigabyte 60XT, and was suprised of the amount of leaking caps for a motherboard of the P3 era. Especially the way the 330µf caps seems like the housing discolored even.
        Now, there are some 3300µF 6.3V KZG series around the CPU. Would it be OK to replace them with something like EEUFR1A332 ? (Panasonic FR 3300µF 10V). Or was this board designed around very low ESR caps?

        But I was also suprised about the bigger boys, which are 330µF 25V.
        Could it be they used 25V caps because they were cheaper / available at that time?...
