    Some points that this video missed:
    - Silver reacts with sulfur in the atmosphere to turn black. It doesn't oxidize under normal circumstances.
    - Tin is very good for plating in connectors because it's soft so it molds to the microscopic imperfections so you have much more contact area. However it suffers from tin pest which means that at low temperatures (13.2 °C and below) it's atoms rearrange in a way that makes it non-conductive so it's not great for cold/winter outdoor conditions. Some people mistake this for oxidation.
    - Metal conductivity doesn't matter in plating. The layer is much too thin to impact it. What is more important is corrosion and wear resistance
    - Copper is a pain to work with. It doesn't plate well, doesn't stick well and oxidizes easily when passing current through it. It's good for it to be the meat of the wire and not the condom
    - Nickel is arguably the best for repeated connection-disconnection. It's hard, resistant to corrosion, fairly conductive and easy to plate (no really, it will stick to most metal like your ex sticks to your bank account)

      Victor, everything you said is correct, except for "Metal conductivity doesn't matter in plating". Research has proven higher conductivity results in lower intermodulation distortion introduced by connectors: ieeexplore.ieee.org/ielaam/22/8681220/8632973-aam.pdf

    • @DaveRat

      Yes! People with boating experience know so much more about this than audio humans. We need boaters designing connectors!

    • @cwize
      @cwize 2 роки тому +1

      The boaters on the thread are well aware of this - many boats have sacrificial zinc anodes connected to other metallic parts that are below the waterline so that they “take one for the team.” Zinc is highly susceptible to galvanic corrosion, and that zinc chunk will deteriorate and save the other parts from the effects of galvanic corrosion.
      Not to mention boaters dealing with problems with electronics & other metal things not specifically meant for maritime use. People with beach houses putting in outdoor speakers almost always find out the hard way that they need specialty components.
      Peripherally audio-related: even stainless steel loudspeaker mounts/hardware can fail over time in high chlorine environments such as natatoriums. Chlorine stress corrosion cracking can affect metals, especially where they are not regularly cleaned with fresh water. Speakers are usually up away from being “washed” so the byproducts of chlorine mixed with impurities can sit and go to work. High molybdenum content stainless steel is much more resistant to this issue. There is “One” speaker manufacturer who has a natatorium series of speakers made for these environments.

    Hmm. I’ve been a Master Plumber for several years now and galvanic action is always a high concern. I’ve replaced many copper pipes that were corroded due to being strapped or supported with steel.
    I had never thought about if or how it would apply to our bands live setup. Very interesting information to consider, as always. Thanks Mr Dave.

    • @victorunbea8451
      @victorunbea8451 3 роки тому +1

      Can you tell a bit more about what you experienced with the pipes? According to the literature during galvanic corrosion the least noble metal gets corroded while the more noble metal gets protected. In this case the iron atoms should flow towards, and deposit on the copper. So why did you need to replace the pipes if they were in contact with steel?

    • @damianthielemier6249
      @damianthielemier6249 3 роки тому +5

      @@victorunbea8451 I’ll try. Typically when I crawl under a house or get in the ceiling of a commercial building the leak is at a point of contact with a piece of galvanized steel strapping (which you’re not supposed to, but I digress). Several pinholes and the like that I’ve fixed in copper have been friction related and will wear from inside out but those are usually really old systems and utilize copper 2-hole straps and the walls have become very thin so it’s obviously friction, IMO. But the ones I’ve fixed that were strapped with iron always have the hole where the steel and copper contacted and wore from outside to in. Obviously, there have been a couple of times where it was a friction issue and the steel just rubs the copper long enough to degrade its integrity. But those are very rare cases, and most of the time you won’t pass an inspection in the first place if your pipes can wiggle at an anchor point. Not sure of what the reasons are (did physics in high school, no chemistry classes), but very rarely is it from friction, they just corrode rather than abrade. Might be one of those “it’s great in practice, but how is it in theory” type of situations where an unexpected result occurs. But again, my experience says that a few will abrade, but the vast majority just corrode up and start leaking eventually. My fuel gas code calls for dielectric unions at any contact of dissimilar metal, but it’s not really applicable to strapping water pipe unless you buy “rubber booted” anchors (not sure of the correct term, I just tell the parts house copper or rubber clamps, depending). And again, this is just my anecdotal experience from 11 or 12ish years in the industry. I’m by no means a technical expert, just an “I see what I see” type of thing. And there may be other mitigating factors I haven’t noticed or accounted for, but I like to feel I assess and diagnose most situations with some semblance of thoroughness. But in my opinion I’m a perpetual student, and no expert in any field, no matter how much “experience” I have. So again, it’s all speculation and personal anecdotal experience from me, and I would assume I should be taken with many grains of salt.

    I've been very interested by this subject for a long time and came across another aspect that I think is also important, that is the conductivity of the metal's oxyde which it will develop eventually. And I remember reading that silver oxyde is almost as good a conductor as silver itself where gold oxyde (even if little of it might appear) is not only a bad conductor, it would be a SEMIconductor, you know, as in chips ans so on... Imagine your signal thru that... Anyway, great shared knowledge Dave, success to you all...

    I have had so many pedal board failures from galvanic corrosion it's crazy. It's a huge problem here in Nova Scotia espesially in the one venue I used to spend at least 100 nights per year and I maintain their rigs in the building. That building is basicially touching the ocean and a few times per year floods during a storm surge and the doors are allways open and the salt air permiates everything. I have traveled with various grades of fine ScotchBrite sheets for many years to quickly clean 1/4" patch cables and jacks on the fly. A great product that I found keeps the corrosion from happening in those extreme conditions is DeOxit Shield S5, it doesnt have the cleaning properties of regular DeOxit D5 but has the continued corrsion protection over time. It was $30 Canadian for a can but the saved downtime was well worth it.

We actually had to stop a show and disassemble the panel and clean all of the breaker contacts with files, scotch brite and contact cleaner to restore proper power. It is amazing how a tiny amount of corrosion will send the resistance skyrocketing. I used to have to Deoxit in ear packs while they were in use quite often as well. The band members would give me a signal and I would blast on stage, pull the 1/8" out of the pack, spray in the 1/8" scrub the plug quick and jam it back in while they were still playing.

    Hi Dave and thanks for your always sensible discussions. As a repairs tech I have encountered this contacts issue countless times and reliable long term remedy ime is 'working' such contacts in conjunction with contact cleaner/lubricant that leaves film of oil that isolates the contacts from air exposure and renewed corrosion. Behringer connectors suffer tin plated contact oxidation issue and is their reliability downfall and cause of bad reputation for otherwise generally great products. Once such contacts/connectors are 'treated' they perform long term as they should ime, ditto for plenty of other makes/models. Out gassing from materials like chipboard and mdf also contribute markedly to contact corrosion issue. Interestingly glycol based fog juice protects connectors, disco/club amps pretty much never fail/act up due to contact issues. PS. I am loving the way you are using the chapter indexes like I suggested to you 👍👍👍.

    With boats they put zinc plates on the bottom to allow the electrolysis to eat them instead of the metal parts of the boat, ever so often you replace what's left of them. The zinc is a soft sacrificial metal, not so easy to simulate in the above water world I suppose. Super interesting, I honestly never thought this sort of stuff happened in the open air short of how big antennas tend to weld themselves due to dissimilar metal fasteners. I guess now that I think about it that would explain why in typical household AC wiring it's all copper on copper or copper on brass connections. There is aluminum too, but again it stays isolated to itself and often has an oxygen inhibitor being used at the connections. Funny how there are actually many examples of it in plain sight (so to speak) but no one ever comes out and explains WHY quite as directly as you did. This really has me rethinking the deliberate intent behind such things as how a typical household electrical panel is constructed and why, let alone the audio stuff. Gets my mushy brain thinking about stuff in different ways. Sweet video, thank You sir may I have another, LOL. hope all is well Dave. :)

    Unrelated to audio, but another major manufacturer that should have known better... Ford. The fuel pump driver module on the 2004+ F-150's has an aluminum housing and sits on a steel frame cross-member above the rear axle, exposed to the great salt bath that happens on our roads every winter. They all eventually fail, often without warning and leaving the truck dead. The revised part includes rubber bushings to keep the aluminum housing about 1/2" off the steel cross-member.

Different topic : old computers sometimes respond well to spending an hour in an oven like 160 to 180°C worked once for me. => that seem to re-settle the soldering points, or possibly cleans some joints.

    I used to fight all the time with Molex connectors on power supply connections to computer equipment on industrial machines. The only sure way I found to fix the connection issues is to cut off the Molex plug and solder the wires directly on the pins. What do you think about products from Caig Laboratories like Deoxit? Channel Master used to make a spray for the silver contacts in the old mechanical tuners in television sets to protect the silver from oxidizing.

    Yeh this is an ongoing issue, something that should be well know but isn't.
    One of my early desks ( back in the 80's) had gold plated sockets for the mother board/loom and plain tinned fingers on the channel boards ...... by tinned I mean lead/tin solder ....... realy bad for dissimlar metals/galvanic corrosion ... i had to go thru that desk and clean and re-tin the edge connectors on every channel a couple of times ...... I ended up using contact cleaner/lubricant in an attempt to keep the air out and minimize the corrosion.
    seen many other situations similar ....... I have seen many bits of audio gear where there are edge connectors go straight onto PCB tracks have caused problems ....... It has been common with some equipment to abandon the sockets and direct solder as a replacement of the sockets.
    Even when I was young I had two pet hates with guitar players .... cheap gold plated jack plugs and curly guitar cords ........ virtually none of the guitar amps, pedals or DI's have gold plated sockets .... so cheap gold guitar plugs where a guaranteed problem, the gold plate did not last long..

  • @SoundSpeeds
    @SoundSpeeds 3 роки тому +3

    So, if I'm understanding correctly... you should solder gold or nickel connectors onto your cables to match the gear they are plugged into. The copper in the cable going to the connector won't create galvanic corrosion itself. Or at least, that can't be controlled.

    • @victorunbea8451
      @victorunbea8451 3 роки тому +3

      It's more complicated than that but you can sum it up like this:
      In galvanic corrosion the more noble (positive potential) element will always attract the least noble one. This means that if you solder gold/nickel to copper then the tin (or tin-lead) in the solder will be the one to corrode leading to weakened connections that can break. Lookup a galvanic potential chart. Generally speaking, metals that are neighbors in the chart don't react with one another.
      However, consider the flow of electricity in the wire. The galvanic potential is no more than 2-3 volts. If you feed 5V to a connector hooked up to the negative wire then it can be made of iron for all it cares, it will corrode even gold or platinum. This is called cathodic protection.

    • @Videditor1067

      @@Videditor1067 I'm saying that the metal with the lowest galvanic potential is the one to corrode when no electricity is passed through it.
      Out of gold, copper and tin, it's tin that's the least noble.
      However, copper and tin also passivate (form a dense oxide layer that acts like a protective coating) so it's only a problem in very humid or marine environments. The key thing to remember with GC is that it's a problem only when moisture is involved

    • @DaveRat
      @DaveRat  3 роки тому

      I have not. I personally am not a big fan of high Q enclosures. Whilst they do reproduce dynamics well, larger horns tend to follow the concept of make a loud box and then process to try to make it flat and smooth sounding. Where as non horn loaded or very short horns tend to naturally sound flatter and smoother and processing is used to make it louder.
      Struggle to get loud boxes to sound good vs struggle to get good sounding boxes to be loud
      Though with EDM or other non live music, the added transients of a horn loaded rig can bring extra life to the sound, with live bands where we typically have naturally too many dynamics, and we are using compression and limiters to tame things down, having a very dynamic loudspeaker tends to make things more challenging.

      It's kind of a mixed bag. Dialectic grease winner connection is clamped with a screw clamp, is all good. But for a connection that can be removed it can tend to build up dust and dirt and then if it is plugged and unplugged at any point that dust and dirt can wedge itself into the contacts and make things worse. But if it's never unplugged and sealed from Dustin dirt it could provide a protection barrier from moisture and corrosion.

    The pandemic may be showing the shortcomings of metal/metal connector contact in the pro audio world. A mixer rental house I know of is going through all their desks right now, many of them nearly brand new, because they've been crashing on boot after sitting for a year unused. Makes me wonder if those desks have mixed metal connector junctions. My own Avid desk started suffering this issue as well. Hard to figure out the exact failure point as it's intermittent and only happens when it's booted cold. After it warms up, it never crashes. Going through and reseating all cables will make it stable for a year or 2. Then it's back. Fun times!

    • @DaveRat

      How do the consoles know? Does turning them on and off stabilize them? Does being moved around make them more reliable? What about studios where the console doesn't move.
      What is it that would cause a console to know the difference between being off for a day or a year or less likely to work after off for a year vs turned on everyday?
      Is there really a diference or is it just a perceived illusion when normally we find all the same faults that occur over a year, during the year and after a year of sitting we actually do d less faults overall but find them in a short time, giving the illusion that sitting dead creates more issues than working constantly?

      Many of these compounds for preventing corrosion are highly subject to attracting contaminants such as dust where the connection is repeatedly made and taken apart in a touring environment. To prevent the surfaces becoming sludge pots of grime, found the best solution is to simply keep them clean, and take the time to clean them regularly. Many spray contact cleaners include a lube, which reacts with the environment over time and turns to a wax, thus interfering with a good contact. Ask anyone who has used this stuff in volume controls, faders, etc and this cure caused major problems later. Do not soak your console faders in WD-40 or other lubricating cleaner as the residue attracts dirt and dries to a wax over time. Edit. Many of the lubricating oils will react with moisture and become acidic and thus conductive and an electrolyte in the presence of dis similar metals making galvanic corrosion. Ask any tech that has tried to clean up old gear about the green scum in connectors.

I've got an old tube of Dow Corning electrical grease that always does the trick. There are also some contact enhancers that claim to work on a molecular level but not sure if its just expensive snake oil.

    i WAS WONDERING if I should spend much more money on gold plated connectors ..... and I viewed it as sacrifice for better tone. But I gather that my pedals don't have gold plated input jacks so it seems it would'nt be worth it at all! WOW! Thank you sooo much. So if I understood you correctly nickel is the way to go, ...right?

      Since the only two real choices to buy moderns connectors are nickel and gold, and gold is more yellow. You pretty much are faced with matching color as the best and easiect way.
      There are some old brass connectors out there as well as silver and copper, but those both have corrosion issues.
      It does not matter too much whether you use nickel or gold but paying extra for gold has no real advantage except if the connectors on the unit are already gold and you intend on leaving the connectors plugged in for very long periods of time.

    or there's connective polymer what's the same conductivity as copper and you can coat your connectors in that
    you only need to mix silver 5% to stop it tarnishing

      I did some looking around, but finding products and such with lower conductivity than copper for specialized applications.

      @@DaveRat yes, best I suppose the manufacturers who make it should have the data sheet! I think it's quite hard wearing it seems to dry hard, I'm assuming it must be something to do with carbon bonds
      I've been having a read up on it and there's lots of different types of conductive polymers used in OLED displays solar panels etc of different variations of conductivity.
      You can buy a little bottle of conductive polymer from chord Electronics they suggest painting the terminals with three coats, maybe you could do an experiment get a metre long piece of non-conductive material and paint three coats and see what the resistances is
      What I can see with organic polymers the longer they left the better conductive is to oxidation where metals are the opposite

      EXACTLY what I was thinking. I had to re-pipe a whole bathroom once because a joint corroded and popped. That’s when I learned that you Don’t Mix Metals. As the guy at Home Depot barked at me. I still have ALL Copper everything in my plumbing tool kit. (And ABS rather than Cast Iron, but that’s another story.)

    Lets talk about galvanic corrosion on sea-going boats, especially ones with an aluminium hull...
    Copper is verboten! Any work involving copper must be carried out in virtually clean room protocol. Any scrap of copper left behind touching the hull will start to eat it away... not a good look on a boat.
    Ohh, the circuit board connectors with square pins... I call them PCB headers.

      My understanding is that connectors that are referred to as chrome are actually nickel chromium alloys and are interchangeable and compatible with nickel. And many connectors that are referred to as nickel are also nickel chromium alloys.

In fact, not worried about the ego side of things, purely concerned with freely sharing helpful info.
