These caps are not filled with oil !!! They have electrolyte between the plates which dries out and sometimes causes the case to expand. This increases ESR and reduces the capacitance of the capacitor. Always re solder the joints with solder using an 80 to 100 watt soldering iron and try walking the component off the board by heating one side at a time. Then use Solder wick and a soldering iron to clean the solder lands before re- soldering new components onto PCB.Replace them and ensure capacitor is correctly anchored with neutral cure sealant to help minimise movement as the sub woofer will cause a mechanical oscillation of the capacitor at high SPL / volume levels.The long lead is usually the positive lead too. Good job Floyd.You just saved yourself a couple of hundred dollars at least as well as reducing down time and freight costs and further handling damage. 🙂

Great fix! Thank you for the video. Sometime that pesky glue is responsible for the trouble. Specially the brown type of glue. As it age and dry, it become conductive and can cause overheating and parts fails. I recommend to completely remove it, specially if it touches the wires or solder points of electronic parts. Once removed, you can than put a new dab of glue in a non-electrical area. Usually it’s ok to replace the caps with the same voltage rating but sometimes manufacturers cut corners to lower costs. If the space allow, higher voltage rating caps would add a safety margin. It’s a shame how many easily fixable electronic gear get discarded because of planned obsolescence. Great work!

You made a huge mistake in not bonding those new caps down to the board. The subwoofer will generate a lot of vibration which causes the capacitor to move slightly, especially when it is at a resonant point. The capacitors have a lot of mass so the stresses are all on the leads and solder joint. Over time, it would completely shear the leads right off or cause the solder joint to fail. I've seen it happen and that is why they put the glue to prevent the capacitors from deflecting and breaking off the leads. You can use hot glue or epoxy to help prevent that type of damage.

@@FloydNashFixItDad It would take a while, but the effects could be a lot worse than just having a 60 hz hum. If the two capacitor are not in parallel, there would be no filtering in the lines at all if the solder joint or leads are broken. The smaller caps are less critical since it has less mass, but the larger ones are prone to this type of failure, especially in a vibration rich environment like a subwoofer. Its relatively easy to apply some hot glue to hold the caps down since you already soldered it down. The work is really to open up the speakers again. The hot glue you are using is much easier to remove. Next time if you have glue on the caps, use a hot air source like a rework station instead of the soldering iron, it softens the glue and makes it much easier to remove. You just use a sharp tweezer and yank the glue off in chunks. The rework stations are perfect since you can control the air volume and limit the heat to local areas. They are relatively cheap and its great for shrink heat tubing.

I think he work hardened the solder joint just going back and forth on the wire to break it off. At the minimum, he should remelt the solder afterwards to relieve the stress on that solder joint. Solder joints don't last forever. There is a finite number of thermal cycling which is worse if the temperature swings are higher. The newer "lead free" ROHS solder is worse because its stiffer and flows at a higher temperature, so they fail quicker than the older 60/40 tin lead solder. A lot of modern electronics fail much quicker than older electronics for that reason.

The glue is to prevent those big caps to vibrate and break loose after some time of using the sub. It’s a good idea to glue them up again after the repair. When soldering the leads, the solder should flow all the way through the hole in the PCB to the other side to make a good mechanical connection. Therefore you should hold your soldering iron a bit longer to the leads (1 or 2 seconds).

I was repairing an Energy subwoofer and it's interesting to see how they all use a similar amp design. Mine turned be the transformer itself which the clamping nuts itself needed to be tightened. However I do think you made a few mistakes. 1. Never buy capacitors from eBay/Amazon. Alot of them are fakes/no-names that don't meet spec...likely why yours looked smaller than the original. 2. Stuff should be glued down and you definitely don't want to burn off that old glue. The yellow glue actually turns brown over time with heat and becomes conductive. I always remove the yellow glue entirely as it will inevitably cause problems later and you might ruin the amp if things short out.
@FloydNashFixItDad Жыл бұрын
My preferred source for electronics components is DigiKey. The whole point here though was to show the average person how to do this repair with as little special as possible. Amazon is something most people are already familiar with. So far, the "cheap" capacitors have been working well for 4 years and have zero issues. If this were a more sensitive circuit then I might have used higher quality components, but this is just a basic filter to remove that 60 cycle hum so it really doesn't have to be that special. I've never actually seen issues with the glue causing anything other than problems removing a component. I've also heard it can become conductive, but so far have never actually seen that happen. I didn't want to burn it off but there was so much of it I had to do whatever I could to get enough off to remove the old capacitors. It's OK to use glue but this was just overkill.

@@FloydNashFixItDad yea, he’s right, that yellow glue, or I think specifically it’s actually nylon epoxy, is an absolute NIGHTMARE. The fact that it has been used for so long on sooooo many different electronic item leads me to believe one thing. There isn’t a chance in hell that the manufacturers do not know that this glue DOES in fact turn brown, become conductive, AND it definitely does become corrosive as well. It can short components out and I’ve seen it many times literally completely eat through the leads on components as well. If it has degraded to that point it’s dark dark brown, and it’s actually much easier to remove than if it was still yellow. Yellow it’s a bitch to remove but the brown stuff can be scraped off relatively easily. For the life of me I can’t believe that no company has been sued for 100% intentionally using the glue to enable planned obsolescence for their electronics. If they had stopped using it after hundreds of thousands of electronics had died from it over decades of use, j might believe it wa unintentional. But after opening up an amp that was built 2 years ago and finding this shit slathered all over it, you’d never be able to conivimcr me thru aren’t planning the obsolescence of this stuff.

It depends on the circuit design for your amp. These can literally be almost any voltage or capacitance. It's whatever the engineers that designed the circuit ended up deciding was best for that application. Match what is in your amp currently so you know you have the correct part. If you have to substitute, go larger. If, for instance, I couldn't have found a 63V capacitor, I would not generally want to substitute with 50V. That may be too small and the smaller capacitor could blow up or not last as long. I would want to find something the same capacitance, but a higher voltage, like 75 volt or 100 volt.

It could also increase the effectiveness by decreasing the ripple that causes the hum in the first place, but I don't think so. The circuit is designed to have the proper size capacitor for the circuit, so I would stick with the one it was designed for.

Great video. I have Definitive Prosub 1000, I plug only the power wire in and it slowly starts humming. It’s not very loud but just enough that you hear it. The sub still works great except for the hum. Does this loud like the capacitors? And on my capacitors they show (M)85°C KL5 - - Neg how can I find the right ones or do you know what ones they are ? I can’t seem to find them. Thank you very much
@FloydNashFixItDad2 жыл бұрын
There should be additional markings on the capacitor that show a voltage and rating, usually listed as uF. If you hear a hum then it's potentially power supply, and potentially those filter capacitors. It can also be the power coming into the house. You can get surge strips designed for audio equipment, or hum eliminators that act as ground loop isolators, that will also have filter capacitors in them to help filter out a good part of that 50 or 60 cycle hum, so that may be an option for you to try as well. If it's not enough to bother you, I don't know that I would try messing with anything right now either.

Unfortunately there are a million answers to such a generic question. It could be not getting power, bad cord, blown fuse, power supply went bad. A cable connection to the rest of the system could be bad. Output on the other unit could be bad or input on the sub went bad. You'll just have to start checking thru things bit by bit to isolate the trouble point

In capacitor what is more important the size or the power(2200uf 25 v) or the size
@FloydNashFixItDad4 жыл бұрын
It depends on the application, but the first thing you want to match is the capacitance (the uf rating). The wrong rating will cause you to have the wrong results for your circuit. Then you want to size it for your circuit. A huge capacitor in a 5 volt circuit won't do anything, and a tiny little capacitor in an application like this, would blow up immediately, or at least not filter like it's supposed to. So, the answer really is both matter a great deal. You always want to try and match the original.

I have a really expensive Revel Subwoofer that is making a loud buzzing sound like the one in your video. I removed the amp and examined the 2 large capacitors that look very similar to the 2 in your amp, except neither have the bulging tops. Is it possible that they are bad and the culprit of the buzzing sound even though they aren't bulging? Thanks for the informative video.

It's possible. If you have a good electronics shop in your area they could remove and test the capacitors, but it's really getting hard to find places like that any more.

Hey Floyd. I did this with a subwoofer and still get the buzz for a second when it powers on. What would I check next?
@FloydNashFixItDad2 жыл бұрын
If it's only for a second and goes away, then I wouldn't change anything. The capacitors need time to charge to full capacity, so it may just be that they are a tad larger than needed and takes enough time to be noticeable. If it operates perfectly after that then I would wait and see what happens and just enjoy it.

Good question. If you have access to a capacitor tester, you could remove them and test them, but that's not something most people have available. You could take it to a shop and have them test them, but that might cost more than just replacing the capacitors to see what happens. If you feel comfortable replacing them, and can get replacements for a good price, it may be worth changing them to see what happens. If that's not the problem, at least you've ruled out a possibility.

You may have to start looking at the circuit for the sub portion. It sounds like it may be a separate circuit with it's own amp, and may have capacitors to help regulate voltage on that side. Look for any caps that may be smaller than the primary ones in the power supply, that have bulging tops to them.

Check the little fuse in there. Mine was a teeny little fuse, something like a 1 or 2 amp and for some reason after replacing the caps it kept blowing immediately. I took a gamble and uses a 5 amp fuse and it's been working great ever since. I think the new caps just have a higher initial amperage requirement.

By this is obviously old, but did you make sure to install the caps with the correct polarity? That could definitely be your problem. You have to make sure they are installed the same way as the ones you removed. The side of the capacitor with the line on in, as well as the side of the cap with the shorter leg , is the negative side. The side with the longer leg and no line is the positive. There is frequently a marking on the PCB with a “+” indicator as well.
