UPDATE: CLEAN AMP PORTS WITH DEOXIT CLEANER TO FIX AUDIO DROP OUT. DISCHARGE THE CAPACITORS BEFORE WORKING ON THE AMP BECAUSE THEY HOLD A CHARGE EVEN THOUGH THE AMP IS UNPLUGGED, SUBSCRIBE AND LIKE FOR MORE VIDEOS LIKE THIS.
hi, ihave valvestate 8080. when the amplifier is not used for a few days., it starts okey..., but when i re start i get a loud hum sound. without volume and no plug in guitar guitar cable. so,i need to unplugg and wait the next day.... :( i already clean the pots with contact cleaner, but nothing happened.
Great I have an old Solid State amp someone gave me & I've not yet ventured into it to see if i can fix it. I hope it's as simple as yours that's a nice rig for your son I've played those Epi LP special II 's really good like a LP Junior basically.Then the Marshall He's got the Strap. Haha my Dad showed me how to clean the pots on my Guitar spraying TV Tuner cleaner i.e. Electronic Contact Cleaner now.
what about hum or buzzing coming from the amplifier? could that be EMI?I have 3 amps that are having that problem. I did not have that problem before?Thank you.Your son rocks! wish I could play like him I am just a beginner.
The potentiometers require lubrication. You'll need to lubricate them with DeoxIT F5 after you've sprayed them out with your choice of electronics cleaner. Do not use WD-40. If the grease was flushed out you'll feel that rough turning action. You'll want to keep them internally greased to also help prevent corrosion.
Way to go teaching kids how to play and repair things. My son is almost 16 now and I have tried my best to do the same with him teaching him how to repair engines and electronics. He plays guitar also and his amp has developed a light humming sound when turned on. So thank you for this video and we are gonna look for the problem this week. !!
I recently bought a Crate GT212 120 watt beast that has what I believe is a grounding issue (after watching this extremely helpful video) and some pots to clean. The amp has tons potential and I plan to fix it! It was great to see a father-son tech team. My father used to let me climb on to the bumper of his vehicles at the age of 4 too see him working on them and do regular maintenance. Your son will appreciate this video more as he gets older. Wish you both the very best!🌎
Thanks for posting this, amazingly I had the same amp as your demonstration. I had a humming sound that went away after cleaning the volume and reseating the solder, I was thinking I would have to replace a capacitor. Your son played great by the way!
As this clip started I almost had heart failure - attacking nuts with long nose pliers At that point my old shop teacher would have thrown anything with sufficient mass at the perpetrators head But the rest was quite informative ~ Thank you
I had to look away. People that careless should be forced to wear some kind of identifying sign to warn potential employers, customers and spouses. I'm talking about the dad, not the kid.
This may never be seen because the post was years ago, but I just wanted to say thank you. I've been trying to figure out what's wrong with my amp for awhile now, thought I tried everything simple, but apparently not the ground wire connection. So thank you for saving my mental health by making this video.. lol
Your son is adorable! The kids nowaday on that age mostly spend so much time seating on the computer & playing game. I bought my son an electric guitar & until now he hasn't touch it. When he was 5 or 6 year old he used to seat beside me & strumming my guitar. Your son at that age, if he will continue playing, he will be a good guitarist. Congrats buddy! By the way thanks for sharing how to fix a guitar amp audio noise.
Thanks for the video. Just wanna ask my guitar amp is noisy when lead is plug in but if you unplug is quiet. Should I troubleshoot the power supply board or just the amp board.
I have a Dean Markley K100B. I purchased new in 1993, the signal seems like it's starting to need time to warm up before it will actually play consistently. I've sprayed dialectic spray were I can. I've played different guitars thru it so its not the guitar. Any Idea's? Does solid state need time to warm up ? It plays well after about 15 minutes of warm up. Let me know. Thanks.
Hi, first let me say that you're a great dad for including your kids on your projects. Now, I have a Line 6 Lowdown Bass amp. everything seems to work fine, except the volume is so low that you can barely hear it. I'm doing some research to open it and see what's going on, and you video just encouraged me to do it. Any advice on what to look for on this case? Thank you so much, and congrats for your channel.
Great Video! I have a question, my old amp is losing volume after a while playing. It still works but the volume goes down very noticeable. Any hints? Thanks!
Way to go buddy... love the video! Great that you include your son. Did the same with my two boys (now 35 and 29). One of my son's now can fix just about anything. He's also the FOH at my church :-) Love the video
VERY helpful, thank you so much for the help. Seven years ago huh? I bet your son is a guitar legend by now! ;) Thanks so much for posting, I'm gonna reference this while trying to repair my own amp!!
Hi. I have a beautiful looking tweed SS amp, 35 Watts and 10" speaker. I've had it from new. I always thought it sounded warm but over time I've had to increasingly cut the bass and mid to almost off and boost the high to max. Even then it sounds very muddy. I only use clean channel but issue is apparent on drive channel also. Is there a particular component I should be looking at to address this? I am an electronics engineer. The amp in question is demoed by a popular RUclips guitarist and sounds much brighter so I'm pretty sure mine is "faulty". Cheers
Thx for the video, I have an 80’s Peavey Musician MK iii 400 Series and it won’t power on, the fuse keeps blowing, I may have plugged into my cab with a different ohm rating. Any ideas? Thx
i'm glad dads like you exist. cause I've rarely seen a young person even interested in rock music, much less playing guitars. Its all about the DJ's and electronic music and autotune. A lot of kids underestimate how hard it is to actually make music because its so easy on a computer. Most music these days are made with the eyes and looking at the positions of notes, rather than what it sounds like
As someone who does both it's kinda funny to hear someone say this. I find it much easier to pick up a guitar to play some notes and figure out melodies. But when I want to produce something I gotta pick a voice, or waveform, set the right dB, think about compression, and what other effects I'm gonna use, and do all the percussion, etc., Ad nauseum. So in the great words of Jesse Jackson "We know that music is music, all of our people got a soul, our experience determines the texture, the taste and the sound of our souls" It's all relative I guess.
Very good tips. I fixed my Kustom bass combo easily. Speaker wiring (factory connections) were loose. I soldered all connections of wires and crackling noise is gone now. 👍🏼
Nice job on this video T.T. , I have a old Crate with audio drop out . I'm a service tech and I'm pretty inclined electrically I just never got around to doing it but I will first thing tomorrow morning. Thanks to your video pro-tips . Thx brother
I didn't hear you talk about the caps but worth mentioning to your son. A quick check to see if the caps had residual voltage on them is always worth doing.
My friend is having an issue with his Fender Rumble 100v3. He says the amp turns on, makes a crackling sound and then shuts off. Do you know if its possibly the power section of the amp? I'm not sure if it's the power supply.
Hypnotize! Brilliant. I have a Laney HCM60R that I got second hand, the "crunch factor" (basically overdrive mode) doesn't work, its super quiet and crackles in and out. Bad solder maybe? Ill try have a look, thanks for this video.
My guitar amp has two independent channels. One channel hums, with a rotating sound, and the other plays just fine. It is old. I picked it up for $300 bucks at an antique store. Will this procedure cure that problem? It turns on fine, but one circuit, powered by the same chord does not receive my signal. AJM
Hey! Great video. Quick question. Just got a Line 6 Spider III today and no matter how far I turn the Master volume or Channel volume up the volume is barely there. Any suggestions? I could really use the help. Thank you!
What about a ringing sound that is tied in with how much gain you apply. I’ve got a Yamaha thr30ii that creates a phone like ringing noise when I turn up the gain. Ty
Great video and very informative thank you very much! how about did you learn about this? I'm interested in music technology and I'd like to learn about it but I don't no where to start. apart from youtube videos
I have two solid state amps. A Randall RX120 head that has audio dropouts and a Crate Flexwave head that doesn't even turn on anymore. This video might just be a lifesaver!
Thanks for this vid. You put more into a short vid than any of the others. I have an Ampeg that was dropping sound. After watching the vid, I hammered it with my fist on top. Working again. lol. Such a rock n roll fix. Guess I might have a connection issue to look at though. Your son rocks; mine just getting started. subbed.
I have a line 6 Flextone 2 that worked perfectly but one day I plugged in my guitar and the volume is a whisper. I can’t get schematics from line 6 so that’s no help. I’m a combat disabled vet and I just do t have money for a new/used or repair costs any ideas? I checked the common issues; burnt fuse: no, obvious shorts: no, loose disconnected wires/connections: no! Thanks I hope I can figure this out
While i was playing PEAVEY VYPYR 30, All the lights flickered and one of the light wasn't. After shutting it off, the tone changed. the red channel i.e high gain seems to have less distortion. Any idea what seems to be the problem ?
I just bought a kustom quad 100 dfx from a pawn shop and when i turn on the volume cuts in and out at first but after like 3 min it plays but then cut back out again any idea what it would be and how much it should cost to fix
Hello Mr Tampatec! Thanks for your nice video. I was facing some problem with my own amp, which is a similar model. (Valvestate VS 65R) Two capacitors were changed, along with a 12ax7 tube and I was pretty sure the problem was solved. (Nothing wrong with the tube, except it is old. So I replaced it with a Russian electro harmonix, cause I was searching for a better sound for my amp. By the way if you have any tube suggestion to make, please do…) I finally assembled my VS 65, but now there is an audible buzz while it is on... It is a bassy sound like note, not a hiss. It is not that loud, but the amp is not so silent any more. If I unplug the jack from the amp's input, it is quite silent, even if I put the volume knob at high levels. I hope I'm not bothering you, so I'm asking: Is this sound possibly coming from the new pair of capacitors that I've changed? The specs of the old ones were 50V 2200μF and 85 o C, while the new ones are of bigger diameter and a different heat tolerance, which is now 105 o C. They also have the OX and 4(2) marks on them, which I don't know what it's about. I also noticed, that the old pair of caps was steadily fixed on the PCB with some thermo-glue, which I didn’t put while I was replacing them. Does it have any particular role in this case? I would appreciate if you could enlighten me a bit. Kind regards John
This is a common symptom of 60 Hz (or 50 Hz) hum. The connection to ground could have been inadvertently affected. Note that there are only a handful of manufacturers of tubes, and they all provide very similar quality tubes. The resale companies simply provide QC.
Thanks, I'll check this stuff. I'm tired of banging my amp on the top. At gigs folks just think I have anger issues. Also, it makes me mad your kid is already better than I am. He just kills it with that Gypsy jam thing he does!
I bought a used roland street cube from guitar center. It arrived with no power cord so no idea if it would work if i had a power cord but i tried couple different sets of new batteries and amp does not power up. I only paid $89 for the amp and usually they are more $ so if i can somehow troubleshoot why it doesnt power up and repair it would be awsome. I have 45 days to return it otherwise. Any ideas what to check or try?
I have a SUPRO 1650RT and everything works EXCEPT no gain and the RECTIFIER TUBE is not lit up at all, stone cold. Checked it with 2 different new rectifier tubes and tube is still a No Go - could the rectifier section have its own fuse?? any thoughts. PLEASE HELP - Very frustrated because everything else works.Thanks.
hello Tampatec, I have the exact same amp with the exact same resistor problem I was wondering if it would be alright if I replaced the resistors with the same 68ohms resistance but with 5w ceramic version instead of 3w?
So I have Marshall V8040 apart. Same burn marks at resistors as you. Test on them says both reading 69 ohms but I havent snipped wire like you. Is the read on both 69 because one is loose off pc board?
I have a Vox Beatle amp and when I turn it on there is just a loud hum. I took the guts out and noticed one of the ceramic resistors in the power section is hot to the touch. Could this mean the power transistors are bad? I did a visual scan and found no burned parts. I think the power section is bad because there is no interplay with the preamp at all just a loud hum. What do you think and where should I look? Thank you, Charles
You don't clean pots by spraying the shaft, you need to get to the actual pot by removing the head from the cab and spray into the pot so that the carbon trace gets cleaned.
I know, that was ridiculous and will do nothing to help clean the connection/signal path. Once he had the amp out he could have shown how to properly spray the cleaner into the pots.
I thought the same as the video stated. I’m looking for someone to help me getting off that loud noise that some amps do when you push the power button
I have the exact same amp. I gave it to my niece and she's been having drop out issues with it. I will follow your steps to see if that resolves the issues - thanks!
I posted a moth ago asking about my volume only going up to a whisper. I checked for cracks,loose wires and nothing! So what do you think it is?? I also do all the work with my 11 year old he showed me your channel.
I have a bugera v22 ,I have had for a couple months now ,and when playing bassy stuff the bass gets woofy and flubby ,I changed the tubes and put in a good celestion. any ideas ??
Adding to previous I own a Peavey pa which buzzes to let me know power is going on but just isn't working..ie doesn't light up etc any ideas on this please.. I run an open mic where I help people get stage experience and charity gigs ..and it's my spare pa used for these gigs ..ty
i have an audio interface tascam us-366. the volume knob is scratchy and i spray contact cleaner on it. but after that, the sound is too slow even at maximum level. why is this happen?
Way to go !! Get your son involved in what you're doing. He'll always remember that for the rest of his life ! Great dad ! I also took note of your trouble shooting experience. Thanks !
Very nice video, man! I have one of these, and had one of these issues. All fixed! Do you ever use the "Preamp out" and "Power amp in" for pedal loop? I'm trying to use it, but there's a pop noise everytime I hit the switch from the pedals (like an amplification of the switch). Besides that, it works great for modulation pedals, especially with the Valve channel. Do you have any tips of how can I fix the pop noise? Tks
Hi there! help me fix my guitar amp.The sound pop up and the led display on the effects turned off/on whenever i strum hard on my guitar. But it works properly in normal condition. Hope yiu can help me. Thanks
i got a marshall ms-2 its a small battery amp. and for some reason the amp will not start up. i seen that the battery was leaking that acid and i cleaned it up.
Appreciate the helpful video's. I'm hoping for a little help. I have a randall rg100 G3 plus. It is a valve/ss. The distortion channel works fine. But the clean channel not so much. It will light up when I switch channels but none of the knobs, other than master volume will work. I don't know why?
I have the same amp and will try this but one thing I need is the on off switch which is busted ..but one knob causes a static noise which I hope the spray will fix Ty..
What about a bad diode? What would that cause? My amp has power, buzz through speakers but no audio when trying to play.. This was after soldering a capacitor back on to board that had fallen off due to bad solder joint..
I have a vox vt30, but now there is a problem. if I play for 30 minutes, the sound suddenly decreases and hoarse. what's the problem?? Please help me. Thank you
Great video!!! I just bought a cheap 20W amp and it doesn’t sound right at all. Going to opening it up this evening and use your video as a rough reference
idk if my issue is damaged pickups or damaged amp. but on certain pickups the sound from the amp becomes very very muffled as if a pillow is placed on the speaker. what's the issue and how can I fix it?

What's the best way to discharge the capacitors?
what about hum or buzzing coming from the amplifier? could that be EMI?I have 3 amps that are having that problem. I did not have that problem before?Thank you.Your son rocks! wish I could play like him I am just a beginner.
The potentiometers require lubrication. You'll need to lubricate them with DeoxIT F5 after you've sprayed them out with your choice of electronics cleaner. Do not use WD-40. If the grease was flushed out you'll feel that rough turning action. You'll want to keep them internally greased to also help prevent corrosion.
Father/Son moment...priceless! Oh, it was an amp vid? This boy will never forget this moment.

He plays guitar also and his amp has developed a light humming sound when turned on. So thank you for this video and we are gonna look for the problem this week. !!
The humming could also be gunk on the strings, a grounding issue, electrical or radio interference, or another mystery cause

I noticed that too.... but I thought what the heck... he was fixing his own amplifier...
AND - he cuts the lead on R63 to test the resistor "out of circuit" but then solders the leads back together J-hooking them? WOW!

replaced it with a Russian electro harmonix, cause I was searching for a better
sound for my amp. By the way if you have any tube suggestion to make, please do…)
I finally assembled my VS 65, but now there is an audible buzz while it is on... It is a
bassy sound like note, not a hiss. It is not that loud, but the amp is not so
silent any more. If I unplug the jack from the amp's input, it is quite silent,
even if I put the volume knob at high levels. I hope I'm not bothering you, so
I'm asking: Is this sound possibly coming from the new pair of capacitors that
I've changed?
The specs of the old ones were 50V 2200μF and 85 o C, while the new ones are of bigger
diameter and a different heat tolerance, which is now 105 o C. They also have
the OX and 4(2) marks on them, which I don't know what it's about.
I also noticed, that the old pair of caps was steadily fixed on the PCB with some thermo-glue, which I didn’t put while I was replacing them. Does it have any particular role
in this case? I would appreciate if you could enlighten me a bit.
Kind regards
John
This is a common symptom of 60 Hz (or 50 Hz) hum. The connection to ground could have been inadvertently affected.
Note that there are only a handful of manufacturers of tubes, and they all provide very similar quality tubes. The resale companies simply provide QC.
Thanks, I'll check this stuff. I'm tired of banging my amp on the top. At gigs folks just think I have anger issues. Also, it makes me mad your kid is already better than I am. He just kills it with that Gypsy jam thing he does!
Will the jack inter change from first act to fender squir
I bought a used roland street cube from guitar center. It arrived with no power cord so no idea if it would work if i had a power cord but i tried couple different sets of new batteries and amp does not power up. I only paid $89 for the amp and usually they are more $ so if i can somehow troubleshoot why it doesnt power up and repair it would be awsome. I have 45 days to return it otherwise. Any ideas what to check or try?
I have a SUPRO 1650RT and everything works EXCEPT no gain and the RECTIFIER TUBE is not lit up at all, stone cold. Checked it with 2 different new rectifier tubes and tube is still a No Go - could the rectifier section have its own fuse?? any thoughts. PLEASE HELP - Very frustrated because everything else works.Thanks.
hello Tampatec, I have the exact same amp with the exact same resistor problem I was wondering if it would be alright if I replaced the resistors with the same 68ohms resistance but with 5w ceramic version instead of 3w?
So I have Marshall V8040 apart. Same burn marks at resistors as you. Test on them says both reading 69 ohms but I havent snipped wire like you. Is the read on both 69 because one is loose off pc board?
Nice job, a good video very helpful for kids and even adults to learn basic troubleshooting and electronics soldering.
I have a Vox Beatle amp and when I turn it on there is just a loud hum. I took the guts out and noticed one of the ceramic resistors in the power section is hot to the touch. Could this mean the power transistors are bad? I did a visual scan and found no burned parts. I think the power section is bad because there is no interplay with the preamp at all just a loud hum. What do you think and where should I look? Thank you, Charles
Song choice by your kid was awesome! A+ on dadding!
Or B+, better, if you're a tube dad.
You don't clean pots by spraying the shaft, you need to get to the actual pot by removing the head from the cab and spray into the pot so that the carbon trace gets cleaned.
I know, that was ridiculous and will do nothing to help clean the connection/signal path. Once he had the amp out he could have shown how to properly spray the cleaner into the pots.
I thought the same as the video stated. I’m looking for someone to help me getting off that loud noise that some amps do when you push the power button
As someone who has dabbled in electrical engineering for my career this pained me IMMENSELY
Good young kid, good poppa! Thanks for the vid as I am having buzz issues
I have the exact same amp. I gave it to my niece and she's been having drop out issues with it. I will follow your steps to see if that resolves the issues - thanks!
I posted a moth ago asking about my volume only going up to a whisper. I checked for cracks,loose wires and nothing! So what do you think it is?? I also do all the work with my 11 year old he showed me your channel.
just found this. I got a Marshall 15W cracking sound so hopefully your video helps. Thanks
So cute how the little was saying “be carful” he really appreciates this Amp
I have a bugera v22 ,I have had for a couple months now ,and when playing bassy stuff the bass gets woofy and flubby ,I changed the tubes and put in a good celestion. any ideas ??
Nice way of demonstrating how to repair a guitar amplifier with your young assistant learning on it.

Adding to previous I own a Peavey pa which buzzes to let me know power is going on but just isn't working..ie doesn't light up etc any ideas on this please.. I run an open mic where I help people get stage experience and charity gigs ..and it's my spare pa used for these gigs ..ty
i have an audio interface tascam us-366. the volume knob is scratchy and i spray contact cleaner on it. but after that, the sound is too slow even at maximum level. why is this happen?
I have a fender power chorus. The volume surges after about 20 minutes of playing. Any ideas what causes this? Can't seem to find an answer. Thanks!
Way to go !! Get your son involved in what you're doing. He'll always remember that for the rest of his life ! Great dad !
I also took note of your trouble shooting experience. Thanks !
Very nice video, man! I have one of these, and had one of these issues. All fixed!
Do you ever use the "Preamp out" and "Power amp in" for pedal loop? I'm trying to use it, but there's a pop noise everytime I hit the switch from the pedals (like an amplification of the switch). Besides that, it works great for modulation pedals, especially with the Valve channel. Do you have any tips of how can I fix the pop noise? Tks
thanks for sharing your knowledge...
Hi there! help me fix my guitar amp.The sound pop up and the led display on the effects turned off/on whenever i strum hard on my guitar. But it works properly in normal condition. Hope yiu can help me. Thanks
i got a marshall ms-2 its a small battery amp. and for some reason the amp will not start up. i seen that the battery was leaking that acid and i cleaned it up.
Appreciate the helpful video's. I'm hoping for a little help. I have a randall rg100 G3 plus. It is a valve/ss. The distortion channel works fine. But the clean channel not so much. It will light up when I switch channels but none of the knobs, other than master volume will work. I don't know why?
I have the same amp and will try this but one thing I need is the on off switch which is busted ..but one knob causes a static noise which I hope the spray will fix Ty..
What about a bad diode? What would that cause? My amp has power, buzz through speakers but no audio when trying to play..
This was after soldering a capacitor back on to board that had fallen off due to bad solder joint..
Thumbs for the talent, the fix and most importantly the father and son bond. Subscribing to your channel right now.
Thank you so much, I just took the head out of my amp and cleaned it up and cleaned all the POTs with contact cleaner and it sounds much better!
Did you discharge anything?
@@daydrmrofficial1966 everything was unplugged and i let it all sit for a while so the capacitors would discharge themselves
Hey Tampatec. On that Marshall 8040 I fixed loose connections installed new resistors. And now spring reverb doesnt work. Everything looks ok.
I have a vox vt30, but now there is a problem. if I play for 30 minutes, the sound suddenly decreases and hoarse. what's the problem?? Please help me. Thank you
i really like your kids's playing. best wishes. good video

Which IC inbuilt in this amplifier
Great video!!! I just bought a cheap 20W amp and it doesn’t sound right at all. Going to opening it up this evening and use your video as a rough reference
Little System of a Down at the end there, nice!
idk if my issue is damaged pickups or damaged amp. but on certain pickups the sound from the amp becomes very very muffled as if a pillow is placed on the speaker. what's the issue and how can I fix it?
usually it's the cable connection or amp. might have blown speaker sounds like so check speaker.
