I currently have in my line rack two Rane Crossovers. One of them gave me cold solder symptoms where at low volume one channel kept shutting down. As l increased the input level the channel came back on. After becomming fustrated with the symptom baleiving that it could have been faulty jacks l removed both the top and bottom lids. Also removed the control knobs and face plate leaving only the chasis frame and circuit board along with all of the dials etc. I then took the garden hose and sprayed the entire inside flushing all of the dials thourally. I then took the leaf blower, blew it out. After that l sat it in the hot sun for a few hours. After that l blew it out with a hair dryer on high heat, reassembled all lids and knobs and reinstalled it in my rack. It sounded like a brand new unit. Literally cleaner and much crisper! As crazy as it sound's, it work's. Work's perfectly!
Nice yard. Tiny shop with wide yard, I love it. Make sure your air compressor provides dry air. I prefer to use vacuum cleaner to clean up electronics devices. My country is very humid so I don't worry about static charge. Nice video. Cheers from Indonesia
what an awesome amp! Sweet toroid transformer inside. Cant believe you got 3 for one hundred bucks! The broken one might just be a blown capacitor or mosfet. Look closely for any bulging or burnt out components, could just be an easy solder job.
Hi. I have an audio amplifier. The problem with it it's that the heat sink gets too hot at higher volume. In the amp it is a factory fan, a 12V one 80 mm. This fan is plugged in a port on the circuit board. I want to put one more fan for better colling, but the amp circuit bord has only a fan plug(a two pin connector). Where can I plug it? Thanks man !
***** Thanks for answer. Could I send you some pictures with the circuti board so you can give me better advice where exactly plug(solder) the fan, thanks a lot !
+rickcperry Hello Rick, take a simple computer fan either a 2" or 4" and run it off any 12V DC power supply or a wall wart. If you have this with adjustable voltage then you can reduce the air flow, fan noise by dialing in 9V or 6V to suit. Place this fan outside the chassis of the amplifier. no need to solder it. Very low cost easy offline solution. Manga.
good that it works for you but sometimes it can be a bad idea if dirt gets lodged even further into some components, especially radio dials etc these can be weak & sensitive to this treatment. I would probably not do this on anything high end & valuable.
Good video. As a touring guitar tech myself, I know amps can get real dusty on the inside. To keep dust out of the chassis and the 1/4" jacks, I use 1/4" jack plugs. I just posted a video showing them and how they work. Have a great day! Sammy Bones #dustyamps #dirtyguitars
I agree, on amps I blast them like this but on a PC where there are jumpers I turn it way down. Good point though, the lower pressure would have done the same job. Thanks for the comment
hey thanks for the vid! im also not a big fan of the canned air, its weak and also expensive. i got a guitar amp, computer and an audio receiver to clean up ..you said stay away from those guys ..stay away from who guys?
+rickcperry You should use a SCUBA tank if you need DRY air at high pressure (3000psi). Used duving tanks are free and they often are used as a loss leader-a shop may sell a tank and 30 fills for $100. So they're cheap.
Why did you put the lid back on without testing it? I always use a DBT (Dim Bulb Tester), thats a 100 watt light bulb wired in series to test the amp with instead of paying $$$ for a variac. At switch on the bulb should glow bright from the inrush current them have a dim glow at most. If you have a short it will glow brightly. That dust picks up moisture and can short the amp out too.
A current limiting bulb, while useful, can only do so much. Sometimes you need to bring them up slowly, and also on an isolation transformer if scoping.
TheEDZEPPELINBAND2 You are correct about the fans, it can generate current back in the system plus air compressors spit out oil, I do not recommend it for most electronic parts.
cleaning technique is quite good but high pressure of air which u applied, does it affect circuit of resister and capacitor in amplifier during cleaning
+rickcperry I think he's asking about the physical force in pressure, not the humidity pressure. And yeah, it's a good idea to use lower air pressure as not to potentially damage components. I use my air compressor too... never had an issue.
i was told those little fans, especially in computers, are only meant to spin so fast, and its best to put a pencil through, between the blades to stop them from spinning, and then blow away, nothing beats 90 lbs of compressed air...i use it all the time...works great on my refrigerator coils too, just roll it over by the door...dust and moisture are the enemy of all electronics-
Pedro Reyes Could be lots of things. Depends on the amp. Could be output or speaker short, could be drive section short, could be power supply. Some testing and know how is required.
hopelly the van's bearrings didn't fail. can I clean an electronic cirquit board of a Kenwood ts 930 hf tranceiver with clutch and brake asbestos dust removal cleaner (those aerosols you can buy by the autopart store)? it removes residue and dryes quickly ! this tranceiver has been stored in a horrific place in the bad company of many dangerous stuff, also broken asbestos roofing on top of that storage bulding collecting dust for years. wich has sticked on the circuit board
Fellow ham here. You can clean it with alcohol from the hardware store and a paint brush. Do not use isopropyl though I repeat do not use isopropyl! Works great for cleaning boards that a capacitor fluid on them.
YOU CAN USE A VACUM CLEANNER.. ALONG WITH A PAINT BRUSH....USE A GOOD SOFT BRUSH.BRUSH THE DIRT AND VACUM IT THE SAME TIME..GOT TO BE REAL CAREFUL WITH THAT.AIR PRESSURE AS YOU CAN UPROOT SOLDER OR LOOSEN TRANSISTORS OR CAPS
Take care of the old amps. They don't make them like that anymore. Today's switchmode class D PWM amps are total crap and not buildt to last. They don't even deliver "real" watts. As an owner of several Crest audio 8001 / 9001 amps I know the difference. They are heavy, but delivers some serious punch!
I would give good money to see someone lick their finger and touch those Caps just after unplugging it... Be like Ren and Stimpy don't piss on that electric fence...
Not wool; skin. The human body sheds its skin at a tremendous rate especially in environments where it's being abraded/worked hard. So a particle mask is a good idea. Not to protect against the skin fragments which are pretty inert but against all the little creatures, microbes etc that live on discarded dead human skin flakes. PS It must be possible surely to safely drain down the very dangerous mains voltage capacitors before opening up a cabinet? I mean, supposing it's one of those or their associated componentry that needs replacing?
Canned air sucks... I never use the shit.... Been a tech for over 20 years.... Holy shit! no wonder the things blew up. That's gross neglect, plain and simple. Using the compressor is the only way to go. I would have pulled the entire channel out after seeing that mess. Most likely, more dust in bad places.... Damn, that was nasty!
Shouldn't your air line have a moisture trap in the line to reduce the water in the line? All compressed air from air compressors produce water inside the tank. Wouldn't it be wise to use a moisture trap in the line before you spray out electronic equipment ?
Depends on the environment, You may need even need to but I like to open them up and check because this is how they cool themselves down and too much crud is like a nice warm blanket
t think the fans are mounted the wrong way because u suck the dirty air in and it cant get out because of the filters. Would make more sense if it would suck the air from the front throu the filter or im wrong? most amplifier are front to back colling
I already use vacuam cleaner...nothing happens...both blover and vacuam cleaner running on Electric motors... compressed air may generate static energy but very less possibility..i already check on google....so how its happening...here you using an air compresser....
Why? I was wondering whether it was safe to do something like this and he proved it was - just have to be careful not to touch capacitors. Think I'll buy me an air compressor.

GREAT JOB VERY HELPFUL///I WAS GOING TO USE A SOFT DUSTER...LOL..AND I HAVE COMPRESSORS AND NEVER THOUGHT TO USE THEM..
Oh that abuse of fine equipment makes me wanna hurt some one. Glad you were able to rescue it.
I use small paint brush and compresor, brush lightly,and blow out amps ..I use them on behringer amps, works great.
Great video Sir really appreciate it nice work 👍🏽👍🏽🙏🏽
i've been using my air compressor for all dust cleanings for many years
Awesome!
I have a Technics Receiver since 1993 and some VCRS but the dust isnt as much as here.

I would suggest using less Psi on your air line , it’s a little high for using on this bit of kit.
I agree, on amps I blast them like this but on a PC where there are jumpers I turn it way down. Good point though, the lower pressure would have done the same job. Thanks for the comment

Because it worked before I took the lid off
A current limiting bulb, while useful, can only do so much. Sometimes you need to bring them up slowly, and also on an isolation transformer if scoping.
A current limiting bulb as you call the DBT (Dim bulb Tester) is all you need if youve had years of experience building and repairing amplifiers.
Now that's a great video! Thanks for the tutorial...
Who ever put the fans in put them in backwards, so they just blow dust right in to the amp with the filters keeping it in.
Behringer does the same thing. I turned the fans around in my amp so that the filters would do what they are supposed to do.
that amp been to war and back!
Should you be using a air filter between the compressor and the line so you don't blow moisture into the electronics?
Probably so, I keep my air tank drained and so far I've never had an issue. Not saying I won't, just have not so far. Thanks for the comment
helpaholic Yes! Even with condensate out of the tank you can still get moisture in the line.
TheEDZEPPELINBAND2 You are correct about the fans, it can generate current back in the system plus air compressors spit out oil, I do not recommend it for most electronic parts.
whats that big round coil, what it is for and what are its uses i really want to know
That's the flux capacitor
cleaning technique is quite good but high pressure of air which u applied, does it affect circuit of resister and capacitor in amplifier during cleaning
+rickcperry I think he's asking about the physical force in pressure, not the humidity pressure. And yeah, it's a good idea to use lower air pressure as not to potentially damage components. I use my air compressor too... never had an issue.
Use your LEAF BLOWER to clean an amp out. Don't waste your time with canned air. Dust is conductive so no wonder they blew.
we have vtech power amplifier we have some problems with it . can u please help me.

THANKZ FOR THE PENCIL IDEA...
nice, thanks
What is you compressure model pls?
That was an old cheap Wal Mart Compressor, Campbell Housfield I think it was. Some meth head decided he wanted it more than me so I no longer have it.
Thanks.
i was wondering what causes a burnt fuse? i have a new amp and the fuses keep burning out? i dont know what causes it. any answers
Pedro Reyes Could be lots of things. Depends on the amp. Could be output or speaker short, could be drive section short, could be power supply. Some testing and know how is required.

You have a short. As the relay is kicking in to stop any damage being done. You might have someone look at it.
Looks like a winner to me...
Will this work for a car amplifier
No
How much Watt mr?
I think it is 300
Oh ... Nice... Waiting another Vidio mr..
Now need Deoxit D100 to clean all contacs
amazing

nice but get the next channel fixed it can cause ploblems later on
Don't use the vaccum cleaner. I recommend Power wash...lol

Moisture traps for air compressors are about $15-$25.
But you would know better. You've had no problems so far :) Good video all around though. :)
Your welcome Rick :)
good
What if I have never cleaned it in its interior life really bad
Depends on the environment, You may need even need to but I like to open them up and check because this is how they cool themselves down and too much crud is like a nice warm blanket
I pay 3.00 per can here. turn it upside down and spray a component and you have cold spray.
As long as oil from the compressor doesn't get in then itll be fine
not bad
De cuantos Watts es ese amplificador pero en español
1500
@@rickcperry gracias amigo
t think the fans are mounted the wrong way because u suck the dirty air in and it cant get out because of the filters. Would make more sense if it would suck the air from the front throu the filter or im wrong? most amplifier are front to back colling
Peavey amps are the best.
MIKE CHIESA Early ones yes, newer ones, no.
What if you don’t have an air compressor? Then what?
Canned air
Discharge caps whenever you open up an amp.
I think if he had the amp set for a couple days with no power I'm sure the Caps are dead 0 voltage
i use my leaf blower...
I am LIKE
Use only vacuam cleaner not blover
Wrong, vacuums create static which WILL damage components. You may find that out one day but don't say I didn't warn you.
I already use vacuam cleaner...nothing happens...both blover and vacuam cleaner running on Electric motors... compressed air may generate static energy but very less possibility..i already check on google....so how its happening...here you using an air compresser....
