Nice trick i usually go and feel smell or touch too see whats hot and if its really hot i change it and usually it is my short . I been installing and repairing amps since the 90s i learned a lot but class d is a different beast and you are the best at explaining how it runs and works all together thanks for such a great channel.

Excellent work. I was going to start a channel doing this for old school amps but maybe I won’t now...you’re a lot better at explaining than I think I could be.

GR8T ride along & data dump. Direct, lots of info and fast paced. Nice combination. THANK YOU..

Brilliant! I would have never thought about that trick with the thermal imaging camera.

Great video as always Sam! Keep up the good work.

I'm going to try this method to fix my JBL PRX718XLF POWERED SUBWOOFER.....The amplifier works fine and the led lights shows there's signal there but no sound...it just cuts in and out if you remember your live video back a few months ago...thanks brother and keep up the good work!

how do you fit all this knowledge inside that noggin I'll never understand. Wish I had 1 day to learn from you. You are totally helpful! Thanks!

I'd like to fix car auto amps ... I build cb amp by hand now .. great work bro ..for sure your smart .

Muito bom, seu trabalho Abraços Brasil

Never trusted those but i end up feeling better because of you teach lol still would rather stay away just like rockville they lack in certain areas now a days it just seems to be better to buy powerful and run at half throttle🙈🙉🙊 with social media these companies and tech people should be able to see these videos and consult people like you it just makes more sense to make them more Unstoppable! #tarampsdead #alpine #kenwood #sherwood #kicker #pioneer #audiopipe #lanzar #amplifierrepair #ampdead #taramps

Absolutely brilliant work!

Very useful info as always :)

great tip using power supply to heat up shorted component. I learned it from old Louis Rossman.

Awesome debugging skills. Can you please let me know how is the modulation done. What kind of device is used as modulator, a normal opamp with high GBP 15Mhz or some transconductance type opamp? Is it not the self oscillating circuit as even without the Fets being switched, you see drive signals? I'm mostly interested to know the devices close to the red preset inbetween the huge copper jumper and bulk capacitors

thank you for sharing your vdeo..very details and easy to understand..i need this..thanks.

Excellent work,thank...

My taramp just done the same thing this past weekend!

Hey Sam, I got two stetsom ex 10.5k's I'm tinkering with. One powers on and puts out signal except bass, soon as a bass note hits it goes protect. The other one is a little sketchy.. I'm at a loss with these Brazilians...lol

Will this help with other makes of amps?

Damn u make me feel like I could fix these things

great job

I've eagerly watched every video of yours I can get my hands on. Ive also search to try find a few books regarding class D operation and amplifier workings. Are there any books you can recommend for me to read? I need to know how the whole thing works and understand that that is a huge undertaking....lol Further regarding oscilloscopes are there any relatively inexpensive ones that you would recommend?

Hey can you tell me the voltage of the zeener diode next to the outputs and the wattage.

Im a newbie and trying to figure out how to do amplifier repair. Im completely lost at what you were explaining. Lool Do you really need an oscilloscope to double check the parameters on the components or can I just check using a multimeter in circuit? What do you use to turn the amp on at home?

sir good day and thanks for the video , i have trouble for on taramps hd3000 to square wave signal generated input of mosfet driver, at the amplifier section i suspect that the comparator chip with dual output (c16 at the schematic) is damage due to emitting lot of heat , may main problem is i don't know if what is the part number. Sir do you know the part number of this chip or any replacement? thanks

I having a problem wit my Hd3000 taramp. It burnt the 2 resistors on the speaker output terminals each on negative and positive sides. It say 10r 3watt on board writing where they were. I changed them to 10 ohm 3 watt resistors but it's playing lower I find I used to get more power. It's like when it's turn up I get the kinda power I used to have at half column wen I test it wit jus my phone and a speaker I test it wit when I just came. Can you help I need to know the type resistors as to color code and what else can be the problem besides

do the timpano amplifiers have this same problem i had a timpano 800.4 that started clipping on low volume

Hi i'm new here and really love what you do...I've got a soundstream XBP-10 that turns on and i'm getting no sound out of it,my sub blew along with my amp I've replace my sub and got the amp repaired but no one wants to repair my Bass machine just by looking at it but i want to have a go at it myself any kind of help will be greatly appreciated

Awesome 😎

Thank you, this video really helpful.. Sub 👍🏻

What is the value of the diode that you've change and the wattage

I have a smart3k and something touched my output terminals well one of them for sure. And now it is making a light rumbling sound when the power comes on. It works ok but it sounds like a ground issue but I know it’s not that because I hooked up another amp to see if it was gana make the same rumbling sound and it was just fine. I think something happened to the output because at first it was making a loud popping sound in all of my 4 subs like really loud. And when I turn it up with a lot of bass it starts acting weird and pops my subs and the amp goes into protect and resets itself but it does come back on. But that light rumbling sound is still there. Could the output to the subs be messed up?

Very good

what do you think i fried in my amp earlier whenever i forgot i hadn’t unhooked the power and stuck a screwdriver in the positive terminal on my TS 400x4 and it bumped against the outer frame for a very brief moment and i got a little bity ark and now it won’t power on i’ve checked and i have 12.6 v at the amp and the fuse inside looks good but i’m gonna check it in the morning and hopefully it blew but i don’t believe it did

Can you fix my audiopipe aqx 3000.1d amp... I bought like ten mosfets and one fda24n40f

Thank for your video very very helpful.....quick question is possible I can mail u an amp so u can fix it an ill pay you ....if is possible please let me know....I like to fix things but I don't have the full equipment an experience...honestly I think I found a new teacher....thanks an I will wait for ur reply....thanks

hi Sam, great video, got a couple of taramps MD8K with the same problems, turning on but no sound come out, how much you would charge me to repair it?

Hey hope all is well with you i was wondering if you probably know why my hd5000 taramp amplifier passing or leaking voltages on the out circut or should i say terminals?

Hi I have a taramps md8000.1 that turns on normally but When you try to play music At really low volume You can barely hear the speaker It starts clipping and protection And it sounds really distorted This is on really low volume

Is there any way I could get you to repair a Rockford Fosgate Punch P400x4 for me?

Could you help me figure out how to repair the cooling fans on my bass 8k ?

I'm getting a similar issue but I found the cause of it was a loose terminal block on the negative speaker side. Is there anyway to tighten that?

Have you repaired any soun digital amps?

I have a ? for you Sam.(barevids) Have you ever worked on an amp that the turn on lead would have a current draw without being triggered? I couldn't find and inbox to send this ? to you personally so I but it here.. Thanks for any help..

hello sir can you help me i have car amplifier mono block brand BUMPER USA.turning on but no sound or no audio out?

What is the difference between the taramps HD 3000.1 and the MD 3000.1. I found them for the exact price so I need it for a single 12 sub what would be better. I appreciate if you can tell me.thanks

I need help with a taramps dsp 3000.1 same problem

If my taramps is cycling power, clip, and protect is it blown? I heard I can reset it by taking out of car and jumping power and ground? Is that correct?

Do you, or anyone else know if its possible to change the type of low and high pass crossovers? I have a Taramps smart 3, brand new. I waited a while before I installed it and as soon as I tried it I noticed I had a high pitch squeal coming from one of the fans as soon as the amp starts. It'll stop after a few min but nevertheless it's there.... and hella annoying 🙄! I can't return it because I exceeded the return period because I had to wait to install due to all the COVID19 BS. Then after tuning it I noticed that this amp does not like low bass notes... it is very annoying. It would be great if it weren't for that, ohh and worst of all some voice creeps through the filters somehow and that makes me want to smash it with a sledge hammer and stomp it like I was doing a Riverdance/B-walk/C-walk! Anyone that could help? Besides the obvious 🙄 of buying a different amp. I have other amps but one is 900wrms and other is supposedly 1kw. I am pushing 2 subs that can take up to 2kw each.

My taramps hd3000 turns on the subs make 5 popping sounds then the amp goes into protect.

Hey bro what is your opinion on the taramps are they good

Emf has a video of why brazillian fullbridge amps dont put out as much power in the lowerhz as his half bridged amps. Shady stuff. I hope you watch it and let us know what you think.

would u be interested in working on 2 of mine old school amp? do u have a email? the earthquake 50 cheater amp 1 Channel not working and same with the zapco amp cant Bridge in the channel as the left channel is not working..

What is the out rca jack for on the smart3?

I always see you probing but where are you connecting the ground?

Can you please tell me the number of output fets

Need help have a taramps 5k in protecive mood

What is the correct value for IC comparator TL702c or TL712c?

Mine not getting no power at all what could be the problem I gotta Md8000

Can you troubleshoot an amplifier with just a multi-meter?

what is model of this amp

U is boss

Could you possibly look over a company called nemesis car audio..

Hey my taramp stop workin wat can it be

What cuase this user error or manufacturer

They quit working after I replaced them an 1 fan got caught on the power wire for the fan itself

Is it just me or does these amp guts look different from other amps?

Can you fix all my broken stuff please?

Can I send u my amp to fix lol it’s my gates they are burnt lol

i didn't get the last word you said.

Funny, you just say to remove the gate resistors ha ha like we know how to do that ha ha
