I worked at a stereo repair/audiophile hand-holding outfit, and we had a test for miniature electrolytic caps we bought in bulk: weigh them. We had an analytical scale that could weigh the difference between Fairy dreams and nightmares; we kept the heaviest 1/3, threw the rest out. The capacitors, not the Fairies! Our theory was that a cap that weighed 2/3 of what it's buddies did is likely already dried out.

The new Jap caps of 30 years ago were all good. They rarely failed in the circuit unless some dumb designer located then within mm of a heat sink. In this case you could nearly always spot them by any bulge on the top.

I'm a professional DJ and owned the Behringer XENYX X1222USB mixer, for exactly 2 years, right until I started to get noise and channel dropouts. A month after buying mine, a musician friend bought the exact same model and used it for... yes, you guessed correctly - 2 years! Exactly the same problem - noise and channel dropouts. Built-in obsolescence is a real thing it seems!

Searching Eurorack UB1202 on google, this video now appears on the front page of search results. Well done

I show the date of introduction for the UB1202 as 2005... Wikipedia has the cap plague ending around 2007... so this could be a real cap-plague piece. Suspicious that none of them popped their seals.

capacitors are the perfect components to build planned-obsolete devices. Manufacturers choose the brand based on the required "timing".

I know of an Australian manufacturer of specialised equipment that farmed out some production to China of a product which was normally manufactured locally. Within 6 months to a year they started getting failures - up to 50%. Since the equipment had special warranties and required an electrician to replace it they had to absorb all the replacement costs involved. A very expensive lesson due to poor quality components being substituted in China.

I've travelled a fair bit to China for work. If caps are being substituted for lower-quality ones it's almost always because the engineers who designed the thing told the CM to chop their cost, not something the CM did of their own volition.

I changed hundreds of bad electrolytic caps on Dell motherboards many years ago. No idea if it was true, but the story was that the cap manufacturer hd been sold counterfeit electrolyte. Another bit of kit I had to replace lots of bad caps on was Thompson TV 1530 cameras. We had some when they were very new and after not too long they began developing a fascinating array of faults. After a few sessions of diagnosis and repair, often complicated by their use of thick film hybrid modules which were effectively “black boxes”, we started to realise almost every fault was caused by bad 0.1UF chip capacitors. From then on, we used to play “spot the cap” and analysis of the circuit would usually get us to the culprit pretty quickly.

There are write-ups about this on the internet. A Taiwan company stole a formula for Japanese electrolytics, but the stolen version was incomplete, missing one or more key stabilizing ingredients. Dell motherboards used them which subsequently started going bad after a few years. I have some HP SFF machines with bad caps that may have been from the same source. So far haven't got around to replacing them.

Even though the caps test as "good", I'd still replace them with nice quality ones for good measure. Electrolytic capacitors are the "secret sauce" for planned obsolescence. I wouldn't be surprised if manufacturers choose the quality to match how long they want the device to last before someone has to buy another one.

Since it's founding, Behringer has always been a company that copies from other manufacturers and aims its products to budget-minded individuals who are looking for the same features you would otherwise have to pay a premium for. Behringer claims to be conceived in Germany, but was one of the first companies to dedicate all of its production in China. As a result they've encountered numerous legal battles with other companies over issues with patents and copyrights. Eventually, they've bought out other professional-grade companies and have, in my opinion, done an injustice to the names these new products are built on. Quality wise, I've always thought of Behringer as the European equivalent of Peavey; it may not sound the best, but it gets the job done.

For amateur use it's usually more than good enough and long enough lasting for you not to feel ripped off when it packs up. I have a similar mixer to the one in the video and while half of it is either dead or dying there are still enough holes, knobs and twiddly bits working to keep it in service after 15 years. I suspect if I cleaned out the dog hair, nicotine and dust I could get most of it working again... But I can't be bothered.

I replaced them with Russian tubes as they had the best reputation for modern replacement tubs.

I also have the UB1202 and it failed after about two years. Two OP amps had gone south so I had no sound output. Quite easy fix and it has been working since. Only cost me the price of the OP amps as I did the repair myself. This was 15 years ago so maybe I should replace the caps. :)

amazing, nice work!

Speaking of the importance of quality caps, I took the main filtering caps out of a 1996 Alpine V12 car amplifier, they are alpine branded 50v 5600uf snap-in caps and one has a v loss of 1.3% still has 5643uf and an esr of .02, the other has a v loss of 1.2% 5821uf and an esr of .03. They have outlived most of the other components on the amp.

Stark, irrefutable evidence of the difference between GOOD equipment made by manufacturers who CARE about quality and are not afraid to CHARGE THE CONSUMER the little extra that GOOD quality will cost. I guess my next mixer will be a Yamaha, or similar. One can remain hopeful that they will source high grade components for their designs.

Oh geez I had to do the same to one of those mixers. I also replaced some of the supposedly noisey opamps but that got only partially rid of the waterfall. So the noise problem seems to be related to the potentiometers and resistors.

I just finished replacing the caps in my Sanyo Walkman. Some of them were completely dead, but almost all of them were more than 20% out of spec, and had a high ESR. Portable electronics from the 80s/90s seem to be vulnerable to bad caps, I suppose from the heat in the small enclosures. But I agree with you that blanket replacing of caps should not be they way you repair things. In fact, the walkman also had a bad volume switch, and that took some time to diagnose. It was an unusual volume knob with both left and right actuation. One of the two sides was tied into the motor circuit.

The main filter cap failed on my friend's Behringer MX602A mixer. He said, "Here, it's yours". I replaced it with a decent Japanese cap for a couple bucks. Still going strong 10 years later.

caps in such low power devices wont bulge, to make them bulge they need to get hot. when their esr increases, they lose more energy to heat, which evaporates / boils the electrolyte causing them to bulge, dry out and esr increase even more. usually they wont leak either, they just dry out over time. even new old stock caps from this era might be bad allready without even seeing a second of use.

I think that the moral of the story here is this. Don't buy Behringer's garbage. I bought a Xenyx Q802 USB about a decade ago. The left channel wasn't working so I opened it to see if it was something relatively easy to fix. Lowe and behold there's a nut from one of the ¼" Jack's wedged up against the left output grounding it to the neighboring ground pin of a nearby jack. I have a picture of it as I discovered it if you're interested. This was fortuitous because one of the nuts they used was cross threaded so it served as a replacement for the fouled one. That's not even to mention the PA speakers where I discovered that they had repaired some miss-cut port holes by filling it up with hot glue. I found this as I was replacing blown drivers which were rated at about a quarter of the power rating on the cabinet. The iNuke DSP 3000 I got from them came with the wires of the power switch disconnected internally. There was a matching amp which was missing it's fuse. I didn't buy them used. They came that way new. What bothered me most was the 250 watt drivers in a 2k watt cabinet and not even in series with the other one in the same cabinet. I'll never buy Behringer's product again. Id suggest Yamaha or Mackie for about the same price. You'll be much happier with either of those.

On a related note my Tektronix TDS-220 scope from over 20 years ago is working fine with no repairs of any kind. It is possible to build quality, but price points seem to be the norm instead. To date it, it supports hardcopy printout directly to Epson 9 or 24 pin dot matrix printers using a centronics parallel port with the optional communications module. Will also print to a Thinkjet, Deskjet, or original Laserjet by HP, if you still have one. This is pre USB, so no saving traces to a thumb drive.

Now THATS a BAD filter - WOW! I just changed 4 Xunda caps in my (new to me) Eurorack "UB2442FX-PRO" power supply. This time all 4 have burst vents. (2 25v 1000uf and 2 16v 470 uf). This replaced a Fostex mixer so it's a step up; but I want to replace all the caps before something else goes wrong.

Thanks for this vid! You make it look so easy though - where do you find replacement caps exactly the same size as the originals?

The list of replacement caps with the exact Digikey parts numbers is linked in the video description.

The final representations of the sounds on an oscilloscope are beautiful! how did you get them? Thanks so much

Link in the video description, but let me put it again here: oscilloscopemusic.com/

Is there a chance you took any close up photos of the board? I have the same mixer with a couple noisy volume pots. I'd like to source and buy replacements before I take the thing apart.

theres a good reason why a lot of my muso mates and myself dont like behringer

Excellent video. Subbed. Time to repair my 802 and 1202 Beringer. What replacement caps are recommended for this recap? And who makes that amazing desildering vacuum? Cheers!

I used Nichicons 105C 10,000 hours when I could, or Rubycons, otherwise same values and values ratings as the originals. The desoldering tool is a Hakko FR-301, I highly recommend it.

Great video and discussion on capacitor life/temp. ratings. Electrolytic capacitors to me have always been a necessary evil. By their very nature they have a finite life regardless of their quality and heat accelerates their demise.

I knew it, but am amazed each time I see things like this... What is used for de-soldering? Might as well get something proper for this kind of task :)

the visuals on the top machine at the end of the video , reminds me of an old piece of software or possibly a plugin called R4 it would do very similar visuals

Next repair video will be the desoldering station. It got to its lifetime operating hours in just this one video...

Let's hope it not Chinese 😂😃lol

I bet if I pulled a few caps from some old boards I have, not made of chinesium, I bet they would still hold value +/-% but not this bad. Some more fun with chinesium was when I got an lm317 in an lm338k package (they were fake). I avoid anything chinesium, if I can, like the plague. Good video.

what's that tool you used to desolder the caps?

Hi Is there any video to how to Replace Volume fader because its only working with Right side left channel is not working from fader or best if i can remove this older fader and by pass fader area with some soldering that means I can use Volume straight with Volume Button only
