I gave this zero chance to correct my problem. I've got a 40+ year old Technics system with an SU-V77 amplifier, SH-8027 equalizer, ST-S77 tuner, RS -B17W cassette deck. I bought two Axiom speakers off e-Bay a few days ago. I've owned the Technics equipment since new but it's had little use. When I put it back together with the Axiom speakers I couldn't get the amplifier volume slide bar past the no. 2 on a 0-10 slide scale without it breaking down. Even from 0-2 it was very scratchy and lost balance between the speakers in most places. Well I watched this video and got some Dust-Off and CRC Electronic cleaner from WalMart since they didn't have the Deoxit. I am in a state of shock. The difference is unbelievable. I can't stand in front of the speakers in the no. 5 position. I squirted here and there just like you demonstrated. I had intended to find another used amp. I don't have to now. Thank you.
CRC Electronic good quick first clean but doesn't do job well wish more place sell Deoxit actually works
Be careful with that CRC stuff. It’s much cheaper, which is great, yet it’s fried a couple of my amps. It worked on several, just never had this issue with Deoxit. If anything, just make sure it’s throughly dry. Jess-sayin.
My favorite dust blower for electronics is a foot pump for air mattresses. It has a hose with several nozels, and it never runs out! You can find them for about $20 not on sale, it has no risk of accidentally freezing if you hold it at the wrong angle, so there's no risk of condensation or thermal shock to components.
Why did you not show you spraying the other controls, balance etc. Those are much harder to get to and I would like to see how you managed that.
what do you do with circuit boards that are so dirty that even after using air to clean them off, they’re filthy with grime from Nicotine? I have a unit I am trying to clean and there’s a nasty layer of Nicotine on the inside, believe it or not. Great video, very helpful and amazing to see how much you accomplished with your approach.
I thought D5 should never be used on carbon pots, and F5 should be the one to use....
These old Tecnics amps and receivers are great pieces of equipment to start of if you are into vintage stereo or if you want a good phono preamp for your turntable. They go reasonably cheap but sound and look the part. Very reliable and quite easy to service, they are kinda like the Honda Civics of audio!
I’ve recently fully restored a Sansui QR-4500 Receiver check it out on my channel there are a couple videos about it like to know what you think
I just subscribed and will check it out. Cheers!
Frank
A single IC stereo amp chip. Those are not great.
As a commercial radio tech, I have used the whole line of DeOxit products for over 25 years, they are a lifesaver for both the customer and I. Their ProGold cleaner is also great on electronic equipment such as old computers that have gold plated card contacts. It’s not that the gold corrodes but there can be a buildup of elements that can condense on the surface of the contacts and even migrate into the joint between the boards and their sockets. It does an excellent job at deep cleaning these connectors eliminating many issues.
Cool, I'm going to make my kid clean the pots, NO, NOT THOSE POTS, on second thought finish them up first...
I bought a vintage 1976 Sansui tuner and amplifier, TU7900 and AU7900 for dirt cheap. Looking to get it all cleaned up and possibly recapped as my first audio project. I’m thinking I’ll add a DAC and some nice bookshelf or tower speakers. I love the green display. Any tips or advice appreciated!!
I purchased an Onkyo TX-41 (not what you'd call a collector piece) made in the early 80s for $9.99 at a thrift shop. I have a problem with the monitor buttons. they don't pop out, they kinda come out slowly and sometimes I have to push a button a few times before it activates (left to right) Tape 2 - Tape 1/Aux - phono - tuner- am/fm buttons. Tape 1/Aux out is what I keep it on for mixing down songs. Here goes nothing! thanks for the video. I'll use it when I get to fixing my Onkyo!
Darn, I threw away a Sony receiver that I used for years. I could have fixed this exact problem. THANKS !
Just picked up a cigarette dirty SA-1010 125wpc for $10...going thru the whole process now. Super gross and someone taped the cord 15 years ago...hoping a heat gun will take the goo off without removing paint.
I like to run a vacuum with the hose rigged to hover maybe 8-10” above the workspace when blowing dust from circuit boards. It does a pretty good job grabbing that airborne dust.
Would D5 work on scratchy PUSH BUTTONS like the loudness / power on-off and others? or would F5 be better?
Simple easy to understand video. Thanks. Could this work using contact cleaner on a technics ch950 sound processor. Getting hum feedback when I press each source on amp phono tuner. (Not the amp as it works with a ch 550 sp.) tape etc. Thank you in advance
Picket up some awesome vintage maggie setup gear from the reciever speakers 8track and 2 record players. All for 45 dollars. Time to clean them up and play them.
Just discovered this vid. Wasn't aware you did this side of the hobby. I have repaired most of my equipment I have purchased and it is also another fun side of the hobby.
would this solve the issue of hearing distortion, etc when using any input on the right channel? I have marantz 2252B and when using Radio, both left/right sound fine, but only when using any input; aux, tape in, etc the right channel goes in and out. Could this just mean a dirty pot for there input selector?
There is Deoxit D5 and Deoxit N D5.
Is it the same?
How about other connectors? Can it be used as other brand contact cleaners?
Go ahead and laugh, but a lawn leaf blower will blast away any and all encrusted dust and crud inside your cabinet - audio equipment, computer equipment, doesn't matter. Your neighbors may not approve when you do it in your driveway, but who cares?
Good idea. I don't have any compressed air but I do have a leaf blower and some WD40 electronic cleaning spray. I'll start on my dusty Yamaha receiver tomorrow. I keep it in a dusty area and It's starting to sound like crap.
Reviewing this video as I am about to work on my receiver, I have the same issue with the volume control. Noticed the cool Stroh’s Beer mirror in the background. 😢
While the pots weren’t easy to get to, the DeOxit worked like a charm. Thanks for posting. Also, not sure why I put the tear emoji in after the Stroh’s mirror comment. Reminiscing I guess.
I just scored a ROTEL RA-1412. I’m here to see how to clean it up.
Wow! Nice find and good fix Frank! I just bought some Deoxit D5 and F5 and will be doing some maintenance work on an old Marantz 1030 integrated amp a lady gave me. She also "got rid" of 2 Dynaco A-25 speakers and a Dual 1214 that needs work. The old adage, "one man`s junk is another man`s treasure" is true! Thanks for posting Frank!
I have a Pioneer SX-1500TD Receiver... Do you think it will work?
Thank you so much for this video. My dad is lending me a similar technic's receiver for my vinyl setup and I know it already has these issues from the last time I tried it out. I thought I was going to have to spend hundreds getting it repaired at a shop, I can't wait to try this out!
And you talk albums that were from 1982.
1.Thriller-
Michael Jackson
2.The Jimi Hendrix Concerts.
What is the risk of shock touching the capacitors is the only risk right if it is unplugged?
Great video!!!! This can definitely help me and save me money in the future!! Thank you very much
Hi Javonte! Please like our Facebook page (facebook.com/CAIGLaboratories/) for DeoxIT updates and giveaways (we will have a DeoxIT giveaway soon)!
I really like the valuable info but could you please stop shouting in the mic, it's a real turn off for me anyway.
Thanks for the comment. I'm glad you find the info valuable. The volume has been an evolution, including fire and the occasional explosion, haha. For me it's fun... but hey, I'm also a KISS fan so that may explain a thing or two.
Sorry to lose you... but I do dig your name...!

Frank
You used compressed air to clean the inside of that amp, inside your shop?! You must love dust everywhere! I worked in video production for nearly 30 years, with all manner of tape decks, electronic gear, computers, shelving... The enemy was always dust, and the solution was a portable vacuum, with a variety of brush and small attachments to reach in small spaces. For cleaning out the insides of electronic gear using compressed air, you do that outside! That aside, thanks for the vinyl and audio gear rescues!
Haha, yes ... inside. There wasn't much dust in there, but point taken. I definitely wouldn't do this in my listening room
Thanks for the comment!
Frank
Channel 33 RPM listening room? I won't do it indoors at all. This is why God made garages, sidewalks, porches, and stoops.
They sell dust masks at dollarama. Good tips. Not bad for 5 bone.
I once use vacuum to clean my amp until one day the vacuum causes static that fkin ruined my amp forever. If you live in a place with high humidity dont ever use vacuum to clean your pcb board
Can i use contact cleaner soray for my kenwood ka 801 amp for cleaning dust and moisture ?
My 1967 Console stereo needs cleaning and I was wondering if it’s safe for me to clean it?
How do u clean push-in selectors? Especially if they are sealed?
How do you clean the push button switches? Mine are dirty and they are sealed.
what do you think of that amplifier. audio quality wise. I have the same one but wanted to know what you think
I think it sounds great and it built well. It is my garage system nowadays.
Frank
Deoxit make miracles !!! i bought this a year ago (also at a musical instruments store) and i brought so many things (amplifiers , cassette deck , etc..) back in life !
It really does, doesn't it? I'm forever grateful I discovered this stuff some time ago.
Have a great week!
Frank
The Jimi Hendrix Concerts
album cover was in
bad shape.
TECH nix. There's no Q in there.
Techneeks there is still no Q in it
Hi Frank! After looking at a lot of solutions, I hope this might do the trick on an old Amp I just got? The left channels (front and back) barely worked and ultimately stopped working completely. I think it’s worth a shot?
Hahaha, you know what? I think that amp hasn’t been turned on in years. I tested with headphones, and then used the test tone mode while turning the volume knob up and down and it cleared every channel 😂😂
Hi guys! Thank you @Channel33RPM for the video! and thank you guys for all the comments! Please like our Facebook page (facebook.com/CAIGLaboratories/) for DeoxIT updates and giveaways.
Anytime!
Frank
Hey Frank,
Great job on the vintage gear fix, enjoyed seeing another garage sale save and always look forward to watching videos like this one from you. Take care and have a great evening l'll talk to you soon.
~. Jeff
Thanks Jeff! You're among the most loyal viewers of this channel, and I appreciate the support. I hope you had a great weekend.
Frank
What is it about the old receivers that make them sound better?
This is great, but your audience doesn't know if you sprayed outside the pot, inside the cracks of the pot, or into the little holes of the pot. In fact you really didn't show anyone what a pot is! I know what a pot is, because I love old amps. Your young newbie audience is at a loss for words. They're going to spray de-oxit on the amp like Lysol on a toilet, like antiperspirant on an underarm. I think you should re-do this video with close ups and an explanation about what a pot is and why it's called a pot. Still, I'm a fan bro. Just some healthy advice. Still gave a thumbs up man!
Good tips. This is an older vid, and of course I am always learning how to improve my video production. Might be worth revisiting this topic in the future.
Cheers
Frank
your mooseheads getting warm. crack that beer
good video, quick to the point and informative. just what I was looking for! down to the type of Deoxit D5 I didn't know the specific type or just how to do it but now I'll try to revive this old 1979 Realistic STA-2100 I just scored for 10$ at goodwill not working. 3$for 2 fuses it works great but dusty so I'll clean it up inside and bring it back to life, I also scored some ADS L620 vintage loudspeakers in mint condition at the same time for 12$ they sound and look amazing together.
Still Sealed, which the album wasn't opened.
The Thriller album is
in good condition.
Hell yeah man! That's much easier than I thought. You have a nice thing here. Quality content and easy explanations! I will subscribe.
Awesome. Glad you found the video useful.
Frank
I imagined the song "I will survive" when he said "I will subscribe" lol.
VICTORY!
I LOVE, LOVE, LOVE when you find something for cheap and you can bring it back to life. Stuff like this is such and easy fix, too. Well picked. I would have grabbed it, too, for $5.
I'm a big fan of the Technics (I say Tech-NEEKS) line - it's what we grew up with. Our first family stereo (our only family stereo, truth be told) consisted of a Technics SA-404 Receiver, a Technics M8 Cassette Deck, and a Pioneer PL-400 Turntable. I picked it out with my Dad and I've been hooked on the stuff (Audio Gear in general, but I really love Technics).
As for finds, you know me (always on the lookout and sometimes successful) - most recent pick was a Pioneer VSX-501 Receiver. It has a phono input and is a rudimentary surround sound unit, but in stereo mode, it has a respectable 100 watts per channel and a pretty decent tuner section. It was $15.79 at Goodwill and needed - guess - a DeOxIt treatment on the volume pot. Works great now. Didn't come with the remote, but it works fine without. Garage sales down in Arizona don't really start up in earnest until mid-September (it's just too hot down here). They run through mid-to-late October. Then we do them all again in the spring.
Other that that pick, I scored a bunch of LPs and a couple of Canon cameras (AE-1 Program and an F-1) but while it's another interest of mine, it's not for Channel 33 RPM. I really have to do a video. I'm trying to coordinate with my daughter to help me.
The SU-V16 is a pretty tidy little unit. Any plans for this score?
Anyway, great video -
Cheers.
Hi Paul. I'm a Tech-NEEKS guy as well, though I have heard others pronounce it the other way. Glad to hear you had some decent pick ups lately. Dirty pots are so often the cause of problems, and as you mentioned, so easy to fix.
Looking forward to one of your vids.
Cheers,
Frank
God Bless you my son... I'll let you know if it works...
Where can I buy Deoxit spray and canned air in the states?
Deoxit is awesome! My Technics SLD202 turntable was playing extremely slow and with a quick spray of this stuff, it plays like a champ!
Thanks for the great info.
Hey frank, you should get that theme song pressed on vinyl! I would buy one!
That would be pretty cool! I'd have to make the song more than 10 seconds though, haha. I really should get around to writing the rest of the jingle!
Frank
Wonderful! You made my life easy. I will purchase Deoxit contact cleaner. I was previously told I need to change potentiometer of my old Marantz 2265B. I will post the result after spraying the pots and other knobs. Muchos swerte!
Deoxit works! No more crackling in my pots.
Awesome vid, now I know to do this, after buying an older component, thanks!
Thanks Aaron. Glad you dug the vid! Hope to hear from you again.
Frank
Great video Frank. Always looking forward to your next episodes. -Bob
Thanks Bob! I appreciate the comment.
Cheers,
Frank
It's sad to think of all the things being thrown out that could have been saved with a little work.
No kidding! It's a simple solution but many folks don't know about it.
Frank
The tragedy of a throwaway society.
I've got several units that need that fix , awesome. can you post the link for the store you bought the spray ?
I bought it at a musical instrument store here in Canada called Long and McQuade. It's pretty easy to buy in the U.S as well, even though Amazon: www.amazon.com/CAIG-D5S-6-Contact-Cleaner-Rejuvenator/dp/B0064BHJTE/ref=sr_1_6?s=musical-instruments&ie=UTF8&qid=1472422664&sr=1-6&keywords=deoxit.
Here is a link to the manufacturer: store.caig.com/s.nl/sc.2/category.188/.f
Great video Brother. Thanks for sharing. I have done this to a couple of stereo receiver's. Always works!!😀👍🇨🇦🌎🎉🎉🎉🎉👏👏👏👏🎉🎉🎉🎉💯🎉🎉💯💯💯💯
Thanks so much, this video was just what I needed!!!
Glad you dug it!
Its Alllllaiiijjvvveeee
I've used isopropyl and find it cleans better and lasts longer than Dioxit- which after time the scratchy POTS comes back.
The proper way to do this is to open up the pots and clean it.
another movie star wanna bee
Thank you for this video Frank. It has solved the problem, and saved me time and money. I just purchased a technics SL23 turntable. These look like they would go great with my turntable. Now I know what to look for. Thank you.
Congrats on the new turntable! Good luck!
Hi sir. Do you have a video on how to clean and restore the knobs itself? Thank you
Ive got pioneer sa 606, pl 255, and ct f950. Thank you
Thanks good show. Yesterday I got freebies to include Technics SU-7100, an Onkyo tuner, a Techniques cassette deck and two nice Allison Four speakers.
Can you do a fix for push button mode selectors? I can't behind mine because of a tight circuit board covers them.
Frank you are the man! What a simple fix, but gotta know what you're doing to get it done!
Thanks Ty! I appreciate you taking the time to tune in.
Frank
+Channel 33 RPM every sunday! you know it!
2 thumbs up on this
So it is OK to spray into these pods, but can you spray the push buttons too. I have a Hitachi ft 340 tuner which the am/fm button is intermittent, would sprayiny into this help. Thank you
does that heart mean a "yes it is OK to spray Push buttons" ??
Yes, it's ok
Hope you did that lovely tuner as well
Gret video man...I picked up a Rotel 1203 amp for $10.oo...Super excited and stoked but the thing is not turning on...Haven't checked inside yet but I believe Deoxit is gonna fix the problem 😂🤣🤣
Great video! I have to get on the Deoxit bandwagon. May I ask how long that Deoxit treatment might last before it gets scratchy again?
Got sansui au4900 2 weeks ago and also I got a static hiss from the speakers when only amp & speakers connected without source. The hiss is totally small. I only hear when I put my ear really close to the speakers. This problems bothers me a bit. Will this help?
@Channel33rpm Thanks for the video! Will be trying this.
I am surprised, you can still find decent audio components-cheap-at Garage Sales. I had thought...people had smartened up by now. Even when you do find classic audio gear at these places, chances are...it's beyond de-oxit.
After years of turning out junk and gaining a bad rep, Panasonic magically became Technics. That amp looks inside and out, really "Panasonicky' to me. LOL.
Should I use Deoxit on my late 1960's vacuum tube pre amp been store for 15 years
Hmmmm... not sure about that one. I don't want to give incorrect advice.
@@Channel33RPM Great video, however, lose the intro (IMHO).
Hey My Man, Thanks for the great video! Actually I think it is because of you that I purchased my first can of Deoxit5- and I am so thankful that I did! It has come through for me everytime and it is worth every penny. I also know the Long&Maquaid Stores well! (Umm..maybe not their spelling!lol)they are awesome. I believe that there was one in Oshawa On? Anyways where abouts in general are you located in in Canada? I'm in the Kawartha Lakes Ontario area. I just picked up this old Signature DR-30 Stereo Receiver for only $25 and although this is a really cool looking unit(it even has those front silver handles that you can pick it up with) I really do not know anything about this receiver let alone who makes them!🤔 If you or anyone else knows about these...I Wonder if maybe you could send some light on it for me? So Thanks again for all of your advice, keep up the great work and God Bless.👍😉🇨🇦
Frank. I gotta question for you. My left channel is always going out on me. Not for long, and if I turn the knobs it often comes back, but it's annoying. What could be the cause of this? I'm going to use the Deoxit on the pots to try to help. But I'm not sure it's the cause.
Hey frank I need to contact you, I want to send you something.
Hi Don. Good to hear from you again. Feel free to drop me a note at Channel33RPM@gmail.com.
Thanks for tuning in!
Frank
I shop at long & Mcquade all the time. I live in ajax and have tons of amp/receivers vintage 70's im an electronic tech amd have been for 21+yrs. We should share notes on equip
Can I use this for my Technics SC-DV290 tuch button to fast and clean the touched contact button?
That is one of the coolest videos you've ever done Frank. This video shows how being resourceful and creative with less than $20 can get someone into audio gear at a fireside price by rejuvenating old audio gear that sounds great when refurbished.
Thanks James
Does that lubricate as well as clean? The big problem I have had over the years with contact restore sprays is that they remove the lubrication from the POT. One of the Deoxit cans says it lubricates, but how does it feel afterwords? Do they still have the dampened feel of a good quality POT?
Thanks for showing off the Yamaha turntable
from the 1970s.
Came for knowledge, stayed for knowledge and Oilers 🤝
what i can i clean a 2270 with that's extremely dusty and the dust is caked on air compressor isn't doing much
Funny I just got my D5 from L+M on Bloor st here in Toronto last night, looking forward to trying it on my old Pioneer with similar issues , thanks for the video
I recently picked up a tape cassette deck at a local thrift store.... I normally wouldn't bother with a used tape deck but this one was in mint condition and it was only 20 years old! It worked perfectly for my 1st 20 cassette recordings... but then all of a sudden it was not recording the left channel. I tested the rca jacks and they are in working order. Any tips would be helpful... thanks
Hi any tips on restoring the shine and glory or the alluminum metal fronts of these vintage treasures mines kinda yellowish.
I getting ready to order some.deoxit payday ,I have some radio shack tuner cleaner and lube ,I never used it yet ,have you ever tried it,I have a midget tube radio it mint condition except the volume knobs cut in our pretty bad ,while I waiting for deoxit ,I was wondering do you think it safe for cleaning the volume knobs with radio shack tuner and lube .anyone help
Worked thank you, I used a electronic spray cleaner from auto parts store.
I had that exact same amp driving a pair of auratones in my recording setup 20 years ago. It was extremely quiet and did the job very well.
I wasn't sure about that amp when I picked it up, but I am still using it, and it sounds great. It is part of my garage stereo set up. Thanks for the comment.
Frank
Sometimes there's an easy solution to this kind of problem, Frank!
Luckily my record collector friend knows how to fix these kind of things if problems are more deeper than this.
Easy as learning the A, B and that third letter whatever it was,
Jarkko / MyVinylBar
Hi Jarkko! My problem is that I typically assume the most difficult solution is the correct one.... It drives my wife nuts, haha.
C is for Cookie.
Cheers,

You can pull the knob off and access the pots from behind the knob
I see that only the right channel is getting power. I just got a old receiver and tuner where the right channel is getting much more power then the right. When I push on the he knob power goes to both channels inconsistently. I hope this works for me.
Just use windex to clean volume pots i did works like a dream excess simply evaporates nice hey!
