I have a Fisher Integrated Amplifier model CA 880. My aunt gave it to me probably 20 years ago, and she got it new back in the early 80s.
Anyway, for at least the last 5 years , the volume knob would crackle like crazy when it was turned up or down. It was so bad that I had to adjust and readjust the knob over and over again just to get the sound to come out of both speakers. So I watched your vid, hit the hardware store for some contact cleaner, and cracked that sucker open. I followed your directions and now there is NO CRACKLE AT ALL and no "dead spots" on the volume dial.
Thanks a million for the excellent instructions!
Thank you for posting this. I finally got my Marantz 2252B and was able to clean controls by following your instruction.
I love your channel. I came across it because I recently picked up a vintage Marantz tuner amp and started doing some research on it. I come over all warm and fuzzy when I watch your videos and I feel like I could curl up on your floor whilst you work on old stereo equipment. It's weird I know but there is something very comforting watching you work. Thank you.
CRC QD should be used very sparingly. Too much will compromise the carbon tracks inside the potentiometer.
Dexoit Gold is for gold plated surfaces ONLY, such as computer edge card connectors. It contains up to 70% naphtha which is a very strong solvent, and will also attack plastics. You do NOT want to use this on potentiometers.
Deoxit F5 is designed specifically for faders, and generally accepted for use on potentiometers. It is safe for plastics.
Deoxit D5 is for metal-on-metal contacts such as switches, relays, and connectors.
Yours is the best explanation for the proper use of these products that I have seen. There is a LOT of misinformation out there on what cleaner/treatments to use where. I hope many people see your explanation. Thank you.
Exactly!... Gold is for gold contacts not for pots! Following this kind of advice you destroy your equipment!
I was just thinking the same thing...
I purchased some Deoxit D5 Gold just the other day, because thier information on the brochure said it was safe on plastics and clearly can be used on precious metals, such as for example gold, silver and rhodium. When you say potentiometers do you mean pots ? Like volume, bass, mid and treble controls ? It's made as an electronic cleaner, so why would it be made unsafe for pots ?
@@odysseus521 I think it is, like a volume "pot" is short for the potentiometer.
For cleaning I use the already mentioned combo of CRC ELECTRONIC CLEANER/ CRC 2-26 lube which are easy to find. I use deoxit f5 if there is an actual "oxidation" issue. That is the ingredient that makes it different. Brick and mortar locations that carry CAIG Deoxit products right on the shelf that may be near you include, Guitar Center, Micro Center(computer store), select electrical trade supply houses, and select appliance repair houses.
CRC QD Electronic cleaner is not easy to find.
Try living in England, you can buy drugs of any description on any street, illegal firearms BUT not CRC QD Electronic Cleaner. 😡
I’ve cleaned large mixing consoles/desks for decades. Use CRC QD to clean, CRC 2-26 to lubricate. That’s all you need and stands the test of time. The real secret is the person doing the job. You can damage just about anything by not knowing what you are doing even with the right chemicals. And don’t tell anyone, but somehow 40 years ago they cleaned components with isopropyl alcohol and lubricated with wd40! The horror!
I remember 40 years ago seeing people do that. It worked......for a little while but always ended up becoming an even bigger probelm eventually.
You're absolutely right about the QD Electronic Cleaner.
You can get it at walmart for about 5 dollars. I've been using it for years and it works great
Isn't 90 proof still good to clean with?
Crackling volume or other pots can also be an indicator of bad capacitors with high DC leakage. The DC passes thru the pot and as you move it, it crackles. Of course if you have sudden loudness changes as you rotate a pot, it's most likely dirty or has a bad spot.
How would you know the difference? Is it dangerous if it's leaking DC? I don't know anything, I just want to fix it.
Dude amazing that it came back to life perfectly. Thanks for the vid and tutorial
back in the day, my Dad used carbon tetrachloride, he had a glass syringe with a needle and put the carbon tet into the pots (potentiometers) dials or sliders.
Thank you so much I have a big rca console stereo I use with terrible scratchy volume, bass, treble etc. Cant wait to give it new life!!
Glad I could help!
Same here I just picked up a sylvania console yesterday and can't wait to dig into the pots with these products.
For your amazement WD40 stands for "Water displacement 40" it has been use for over 50 years in the boating industry to dry and promote electronic contact in wet ignitions systems of boats and of cars. It was also use in the boat store next to my house when I was a teenager for contacts and switches. Making them work instantly. It was manufactured for that. People now a days use it to lubricate when this IS NOT A LUBRICANT like penetrating oil but will leave a small oily lubrication since the main component is FISH OIL... I don't use it for potentiometers... when I get a bad case of a dirty POT I just disassembled it, cleaning by hand with a Qtip or whatever needed and re-assemble it back! And that turn out to be a super clean pot...
There is no fish oil in WD40, they actually straight up called that out on their site lol.
Can we use WD40 to clean volume controller of amplifier ?
Oh my gosh. lol. Good Job! nice to see someone get excited about pots! lol.
I've decided to give it a try. Thank you!
I have seen some warnings about using D5 on carbon pots, since it attacks the trace apparently. So following up with DeOxit Gold or Fader lube (F5 in the green can) is recommended. Mr. Carlson's Lab (super expert) even recommends using Specialist Gel Lube WD-40 (not normal WD40!), formerly known as "Spray-n-Stay". It prevents oxidation and water intrusion and provides smooth operation and good contact for a long time. Your instincts about this are good, and thanks for the tip on a lower cost solution! Saw your warning about WD-40. Specialist Gel is different stuff and it's not for cleaning, it's for preserving the clean contacts.
I haven't watched Mr. C for a longtime, I will go and try to find his video on this subject as I'm always willing to learn. I have been cleaning pots and sliders like this for many a years, before the CRC I used to use Blue shower (old formula) then fader lube. Just made sense, to me. Thanks for watching. Cheers
@@breakerbroke23 Thanks for your reply! The Mr. Carlson cleaning video is on Patreon, so it may require a subscription to his channel. It is called
"Mr. Carlson's VR and Potentiometer Cleaning Process, Also: PCB Breakout Board Release!" on Jun 15, 2020 at 9:49 PM
A friend of mine that has been doing electronic repairs for years, uses LPS-1 as a final lubricant. DeoxIT Fader 5 in the green can and then the LPS-1.
Radio Shack has brick and mortar store near me. Stores are rare, but they exist.
Thanks for given me courage to spray the volume potentiometer, now my loved Rotel RA-935BX sounds flawless again. If CRC wont last that long, I buy Deoxit
Deoxit markets its F5/Fader product as for use with faders and potentiometers. However, if you read the company's product guide for audio gear applications, they recommend *only* F5 for faders and *only* D5 for potentiometers. At least I'm not the only one confused.
works great on guitar volume and tone knobs too
It's amazing at how many Stereo receivers from the 70's and 80's that I've found at thrift stores that people donated because they thought they were junk because of the oxidization on the contacts . I've found at least a dozen higher end audio products over the past year or two that only needed a simply cleaning such as this that I paid like $8 -$15 for 😉. So keep donating them dummies 👍 .
Copy that 100%. Cheers
Totally been scoring too!!! $4000 for $249…. Just a cleaning.
Thanks for the vid, just used the CRC on my car stereo's volume knob and now it works like a champ, saved me the cost of a stereo replacement!
Glad it helped, if the scratchy returns then give a squirt of DeOx.
Oh my! I still have a can of Radio Shack Archer TV tuner cleaner, and it seems work well on all apllications for me.
I have an old Onkyo pre HDMI era and a couple Yamaha receivers that all have pops and volume control issues. Just ordered the prewash and will attempt to spray it in there.
Good video. Glad to know Radio Shack is still around, i thought they were gone for good.
Just cleaned my old Cambridge Audio A1 MK3 - oooh it's like butter, nary a crackle! Lovely :). Thanks again for the video.
Great to hear!
Great, instructive video. Will do this on my Pioneer SA-8500, as the right channel on the volume button has a lot of static when turned. Strangely it dissapears once amp is warmed up.
Good stuff 👍. I've had good luck using Deoxit F5 on variable pots / switches, especially the sliding volume in the older Turner hand mics.
yea, I use Gold on those pesky Turner mics :)
Thanks for the video, dealing with a Harmon Kardon from the 80's, so much power but it is CRUSTY!
Well done.
I just got a Pioneer SX-450 that's very scratchy. I tried doing this with D5 and it didn't work. I'm not sure I got in the pit correctly. I didn't take off the bottom cover though. I'm gonna give this another shot now. Thanks for the video.
Good man! I love my old Cambridge Audio A1 MK3 but it's getting little crackling with the volume and it's so annoying. I'm not technical but this looks pretty straight forward. Thanks for the help!
great video I have the 2238 but having never done the cleaning it would have been nice to see how to undo the 'knob nuts' and the actual 'peeling back' of the circuit boards covering the knobs.
Noted.
The WD-40 contact cleaner is just as good, and you get more of it in the can so more cost effective if using it a lot. I always follow it with a blast of compressed air. If the carbon pads inside the pot themselves are worn away then there's no saving them time to replace them.
Is the WD-40 contact cleaner any good...?
CRC QD Electronic Cleaner is unavailable in England.
Deoxit gold is just an extremely mild form of deoxit. The "gold" indicates that it's intended for use in applications where precious metals are present as they can be harmed by something as strong as normal deoxit. Classic deoxit is 20‰ cleaning agent by volume. Deoxit Gold contains a mere .5‰ (one half of one percent) cleaning agent by volume.
I understand, however I have been using this combo for years with great results.
As they say..... works for me.
Cheers
Sokniko01..so, in ur opinion..you dont need the gold?
@@lazymug That is correct. Deoxit Gold is just a super diluted form of Deoxit made for use on precious metals such as gold that might be negatively impacted by the use of the full strength Deoxit.
Is Deoxit Gold safe to use on the Marantz pots ? They have silver contacts within them I believe
Good info thanks bro
No problem 👍
Does the older marantz recievers have carbon in thier pots ? I thought they were silver contacts ?
The Red Deoxit is not intended for Pots, its only meant for Switch contacts eg. Brass plate etc and so will kill the carbon tracks inside pots over time & sometimes in fairly short order and isn't great on fibre board PCB's in older equipment....!!!!! The Green F5 Fader Deoxit is intended to be safe for carbon or other resistive tracks and won't kill your pots or faders.....And the Gold one is specifically for Cleaning Gold Plated Contacts....All seem to be really good for all of their intended uses....
I have an old audiovox in a 69 camaro. My aunt bought me the radio on my 15th birthday for that car. I still have both, but my aunt passed. It's a cheap radio, but has sentimental value. This would probably fix my volume issue, it was extremely jumpy but it has quit all together now.
I would give it a try. Remember, CRC First then the DeOx.
Deoxit Red is not meant for carbon potentiometers. It will degrade and eat away at the carbon over time. Use the Green Deoxit. The red will work great at first but over time the pots resistance will start to fluctuate because of the carbon break down.
Thanks, I will look into that.
Very helpful. I have a couple of 45 year old units that have never been cleaned and need this kind of tune-up.
Glad it helped
Great video man!
Appreciate it!
You can also use Gumout carburetor cleaner and brake cleaner the WD-40
The CRC CAN is for automotive use only! You use that for Terminals connector like your headlight connector. That's not for electronic use.
You are wrong my friend, but hey... Thanks for watching.
I use it on all electrical
I use it for cooking, never had a problem.
Sadly my amplifier pots don't look anything like that on the back, it's a square with some tiny holes and not this circle with the entrance where you can spray the contact cleaner...
Great vid
Thank you very much, kudos.
Very nice video !
Thank you so much.
Great info thanks
CRC QD Electronic Cleaner is unavailable in Britain.
I just picked up a Teac A-7010 reel to reel tape player and the power button seems to be gummed up. I will follow your advice and see if that solves the problem. Crossing my fingers, hopefully that works! Thanks for the video!
Soak the switch with the CRC, (get as much as you can inside )
Let it soak for a minute or so then try to move the mechanism on off on off. I had a technics receiver come in that the power switch would not move at all, I thought it was a bad or stuck switch, so I first sprayed in a bunch of CRC let sit and did it again. The switch freed up and still works like a charm.
Don’t forget to use the DeOx to lube it up.
@@breakerbroke23 incredible!!! That worked like magic. Thanks you so much for your feedback!!!
I hate ordering g crap online. Now a day you can't walk into a store and buy UT anymore. Order this and order that. Wait a few days while the product sits there collecting dust.
Thx for the info
All these contact sprays will eventually dissolve the grease that keeps the gear inside the volume pot lubricated.
If you are to use a contact spray to dissolve gunk build up, make sure to re-grease it afterwards, otherwise the gear inside the pot is made of plastic and it will dry up, start cracking and eventually break and then you won't be able to turn it at all.
Been doing this for decades.... Never seen this happen. Ever.
I've got 2 onkyo m504 amps. I picked up in the 90s. Never had them open. How do clean the built up dust from inside? QD electronics cleaner?
Yes this helps! But I have to clean the pots on a 64 channel mixing board. I'm thinking I could buy another one cheaper than cleaning. But I don't throw anything away. Even if it cost me more to fix it. I should had been smarter when I stored it before I tried to use it 10 years later. I will always own up to my mistakes. That's the only way our viewers will learn. Learn from others mistakes. Not your own. It will save you a ton of money.
Me too Bro: If, i am guilty of something? I will be the 1st one to admit it. I could never steal anything? Because i'd be the one to Ray my own self out. Lol. Just the way i was raised. I was raised by my Grandparents & i guess that I'm just an Old Soul? But, i am Proud of it. I Love Honesty. God Bless you Bro! .
thanks
Years ago there was a hyrocarbon spray called FREEON... Oh how i miss it.
I think that was r11,it was in an orange jug,20 lbs,r12 was white r22 was green,r11 was strictly a cleaner for compressor burn outs,it was great and great for radio work also,I use to get it for abt25 bucks a jug back in late 70 early 80s😊
Nice. Just picked up a Sony CD player from 1980s. Headphone volume control definitely symptoms like yours. Min volume not silent, mucho static in right ear headphone. I’m going to purchase the service manual just for kicks but your fix is great. Anything no similar for CD Player laser track/rail clean and lubing?
Back in the day we used a drop of singer sewing machine oil then I used a Q-Tip to dab off any extra oil.... a tech back then told me to not put any oil or lube on transports or mechanisms. IDK this technique worked for me but I never seen any gear come back in so I was not able to see the after effects. Cheers
Can u do a Carver 742? I cant get to my switchs. Thanks
Could this work on a loose potentiometer?
I have a Harman pellet stove do you think I can clean the control board? Is there a good way to clean the control board to help it lest longer? Do you think it would be ok to use a can of DeoxIT D5 to clean the dials once a year to help the control board last longer? If you think this would be ok should I give each dial a small spray then turn the dial then let dry?
I would blow the dust out every year and go from there, I don't see where a shot of DeOx would hurt when doing that regular maintenance. I like having a can around anyway.
@@breakerbroke23 thank you very much for getting back to me hope your channel is doing good
Hey I just purchased an old Radio Shack SW100 am/fm/sw radio and it has a fine tuning knob in the center of the larger tuning knob. Both knobs rotate freely and smoothly but the fine tuner feels like it doesn’t always grab so to speak and will only erratically move the needle. I assume its geared and only actually supposed to be spinning the larger outer knob when you turn it but just slowly? Should I attempt something like this? I’m not sure how easy it is to get into, could I just pull the knobs off and try to squirt this in from the shaft end? Great video btw.
Hello, I don't think just taking the knobs off and trying to get DeOx down the shaft would work, I think it need to be assessed from behind. I have never been into one of those rigs (cool as heck rig BTW ) so I don't know how that knob functions. There maybe be a tension spring on the string dial or the pulley on the tuner cap... Wish I could be of more help. Good luck and Cheers
EDIT.... I wounder if the tuning string has slacked a bit and is slipping.
Could you put a little dielectric grease in there to keep it "fixed"?
I wouldn't.
Grease can sometimes collect and trap dirt which can lead to poor contact in potentiometers
You want to always use something that can break up any dirt and debris but also evaporates really fast.
I have a old Onkyo receiver no static in the vlume control although i have had 80's stereos that have done that. What's happening to my unit is the right speaker will cut out and if i rapidly turn the volume up and down it cuts back in. Will this method work that you are showing us?
yes
I wonder if you could use the gold on the cap-stand inside an 8 track player?
You could but I doubt it would last long. We used an oil that was (IMO) like 30w oil. (One micro drop)
we buy that Crc elec cleaner by the case I can permanently smell it🤣🤣🤣
Would 'contact cleaner' fix - Static noise, when turning the volume knob?
It should
Is there an alternative to CRC QD Electronic Cleaner, as this product is unavailable in England...?
IDK, not familiar with the euro market. Just look up Electronic contact cleaner or Tuner Wash.
I'm guessing you work on CB radios also👍Im a cb junkie i figured from your channel name?
I work with CBs and Car Audio. Started in CBs at the age of 11 and got into Car Audio at 16 (1979). Owned my Car Stereo Business for many years then bought an RV Park in 2002, sold my Park 7 Months ago and am now going back to my passion of Car Audio. These kids are bulding some insane stuff nowadays. Its fun "learning " again.
@@breakerbroke23 Thats awesome Ive got so many cb radios I cant count them 🤣 been collecting for along time current one in my truck is a Cherokee Cm-10 the one you can mod the chip but prob never do it.👍Its cool you get to do what you love.
What does it mean when you have to repeatedly keep using contact cleaner? I have a receiver that worked perfectly after doing this, but the problems with the mail volume knob (crackling and just plain not working) keep coming back a couple of weeks after cleaning! I suppose it means that I've got a worse issue.
I would start looking for a new control. I have had a pot haunt me. Eventually I just replace it. If its a vintage receiver, maybe start combing ebay for one.
NU-TROL is another option!
I bought the D5, the gold, d100, and fader for a 4 can variety. I plan to use the crc/d5/gold combo you suggest, but where would the d100 or Fader come into play?
IIRC fader is cleaner but more of a lubrication. I used it on slide controls like L&R balance on Marantz receivers or slide volume controls on CB Radio power mics. IMO al the De Ox products work for general cleaning and can be used in combinations that will work for you or your application.
There are a lot of OCD You Tubers that will argue this way or that, however at the end of the day experiment and use what works for you. You cant go wrong...
If you don't like the results then just clean the pot with CRC and start over:)
D100 is pure deoxit d5 is 5%
I used Deoxit D5 on my guitar pot, -now it has zero resistance when turning .. it turns by even just slightly bumping it with my finger.... How can I get it like it was?? Is it permanently damaged?
Replace the pot. It was more that likely bad quality anyway. IMO, however it is hard to tell without seeing with my own eyes. Cheers
I use cleaner that I can get in stores here (Deoxit is amazon only) and have found that the cleaner fixes my problem (scratchy static on the volume knob) but a few hours later once its dried the sounds come back. Will D5 fix this and make it last forever, or do I need just the gold? Or...something else?
Follow up with some D5, that should take care of it. But before you add the D5, flush the pot with your cleaner first.
@@breakerbroke23 ...I ended up just going with WD40 >
We have two Rat Shacks here in Tennessee...
This can use on ddj sx2 pioneer DJ? My cross fader is bleeding
Yes this may work well for you maintenance wise, not sure of the "bleeding" issue, that could be a circuit design thing in conjunction with dirty fader control? I would be interested in your results. Cheers
hi i own a kenwood amp, volum is just like yours, but a channel kicks in and out to, is it because its very dirty, kind regards mike
Volume, spk A&B, Mode sw, ballance control. All of these can give you problems. I do all mechanicals.
Is that jack black detoxing this unit!?
I keep hearing about this Jack Black guy.. So, Thanks?
Cheers and thanks for watching.
can you use WD40? will it work? Thanks
IMO... Don't use WD40, stick to the Deox.
the wd40 contact cleaner is actually quite good too
I will give it a try.
Mag kano each
Deoxit has a blue can/bottle called shield I think. It’s for shielding the contact surfaces. It’s probably all very similar though $$$$$
I will have to check that out, Thanks.
No se ingles
At least try and catch the dripping liquids - they are often sticky and nasty- the last thing you want dripping onto the components. The amount of times i've picked up gear cleaned like this by amateur audio nuts as 'working' and they are full of gunk is ridiculous. Your method is always a temporary fix - and the best solution is to take apart the pots and clean properly. For a 'quick fix' that last the longest- I recommend Isopropyl works best from my experience and 100% evaporates.
Wow. 3 cans.
2 ads just to watch this vid c'mon man!
That's gOogle for you.
But thanks for watching anyway.
Cheers.
Can i use wd40 instead?
They make a WD40 Electrical Contact Cleaner or Specialist Contact Cleaner those are safe to use. Don't use the regular WD40.
I remember I had a problem with my speakers years ago, they still worked; However, they stopped working after I disconnected everything, then reconnected them. I'm actually reluctant to try cleaning my speaker now, because of that-And it's getting fuckin bad.
I check the volume control AND speaker select switches as they are seldom used and they get dirty/corroded from lack of use. I hope you "fucking" get your tunes back. Cheers
@@breakerbroke23 Yeah, I'll have to FUCKING break down and attempt it eventually,
Actually, I should ask- does black circuit board discoloration mean it's fucked? Whatever caused it...
I think I threw that speaker set out, so I can't show you.
Discoloring is most always a sign of heat.
@@breakerbroke23 Which means...
Somethings fucked up!..... IDK..... send a pic and I will take a look. That info is in the about section.
*DO* *NOT* *USE* Deoxit D5 (Red can) in a pot. Over time it will ruin the pot.
*DO* *NOT* *SPRAY* anything into your gear while it is plugged in or turned on.
Pots work by using a carbon slide surface as a variable resistor. As the slide contact moves along this carbon surface, it increases and decreases the resistance. A volume pot is a variable resistor.
Deoxit D5 will destroy that carbon slide surface over time.
*USE* *Deoxit* *F5* and don't spray it where you have it dripping out of the component.
Especialy if you're using it to clean a variable capacitor type fader or knob. Spraying too much into it can short it causing it to release the stored electrical power inside it at the wrong time.
You only need a quick burt of it. You immediately turn the pot to work the cleaner into it. Then blow it out with come air.
brake cleaner doesn't work?
Wally world 😄
Can i use wd 40 contact cleaner?
Although I have not yet used this product I understand it works good.
Don't use wd-40
@@fredvelasquez4011 wd40 now do a specific contact cleaner (as well as regular wd40)
I've sprayed WD40 many times in faulty electronics, and the fault is no more. But not on a $10k device.
Sorry, also used in my car. Its literally magic.
g5 not for pots
D5 works very good for pots and gold can be used as a followup treatment. Back in the day I used D100 as a followup but found in mobile electronics ( Car Stereo, CB Radio ) it would attract dirt particles. So the system I use now I find to be most useful. But hey, to each his own.... Cheers.
@@breakerbroke23 wrong
Don’t use the red with pots!!! Use the green, and gold! Red will eat the carbon tracks of the pots! You also need to take the pot out, take it apart clean all the contacts and then use fader grease. You are doing this all wrong! You just washed all the grease out!
It's called deoxit not deox. Lol. Can't take anything else seriously after that.
The camera work on some of these channels is absolutely terrible. You are supposed to avoid inducing motion sickness.
you said you never used wd 40 then how do you know its not good?
I have used WD40 for automotive work for decades and I am very familiar with its properties for that type of use.... Electronics? no way.
This is a what NOT to do video!
I’ll forgive this guy for he don’t know what he do.
You need “fader lube cleaner” for these .
His way will ensure you losing your equipment.
What if you did exactly what he said, and got it with fader lube as a last step?
$24 a can. Too high for me. Potentiometers love oil.
A can is not that expensive if you think of how many uses you will get out of it and that can will last for years. IMO
Cheers
