hi my name is call Bryant, I enjoyed seeing you work on the amp and making repairs being very thorough I like the fact that you check all the different systems and make sure they're all working properly and doing their job which makes you a excellent technician, be caused in my past I've had friend I thinking they took shortcuts and it always turn out something would be wrong with it and I would have to bring it back.

I love the amplifier repair vids! I just started doing repairs about 10 months ago and these videos are helping me soooo much. I had the transistor replacement side of things down ok but I needed some knowledge dropped on me about the driver boards and how the control things. This is helping me out tremendously! I also buy a good used amplifier to match the one im gonna fix. Then when im done i sell both. Please keep making these videos! Thank you so much again! The hifonics brutus 2400 and 2500's that have the same board as the soundqubed 2200's is the main ones im learning on because there so cheap when blown and sell fairly well when fixed. There also plentiful and that board is in all kinds of amps!

Love these videos bro, please keep them coming, love learning these techniques!

Great videos. I'd repaired some classes d amps about a year ago by replacing components. These videos help me understand troubleshooting and what to look for. Keep it up.

I love these videos, man I learn a ton from them. keep em coming brotha!

I love your amp repairs, Keep them coming!

Man this was before your thermal camera, I use a cheap digital thumb readout that I bought for my nitro R/C trucks. Inexpensive and effective.

Some of the best repair videos on the interweb.

Thank you for the info about batch , I made that mistake and didn't realize that was a issue

Keep the amps repair vids coming

Top job mate. I get a lot out of your videos!

Great to see that you continue to be a top shelf legit Amp tech. What sucks is you're in the UK and I'm in the US. I know this is old, but get some real pro grade PCB tweezers and tools. ;D

When is your next video coming man? Looking forward to seeing what you're working on next!! Keep up the good work.

Very good videos learning a lot considering I used to do amplifier repairs, brilliant

Great repair video thanks man i learned some new stuff like never to pick up something right away after you now heated it lol seriously very informative keep up the good work

really enjoy watching the repair videos. this is knowledge I've looked for for years! keep up the good work! could you possibly show the difference in the guts of say a class a/b amp and a class D amp??

i love the video you put love in to your work i have 3 amps with protection light on

I do enjoy watching your repair vids. Please keep this content in your videos. I wish I could send you my two power Akoustic LT 980 amps to be in your videos.

Thanks again for all the videos Sam. I can't wait to get a scope so that I can sit and do some repairs (or at least attempt) while watching your videos. Maybe one day we can do a live feed of us working on amps together. LOL

I'd be totally down for that!

Watching on a Galaxy tab s4 with quad speakers and each time your phone had a notification I looked to the right as it sounded like there was a phone sat next to me!

indeed a great execution. i didn't realize how interesting this would be. is it possible to hop up an amp?

the cool thing about your videos is this can all go with also just Power inverters, that take like 12 to 48 volts depending on set up and convert it to 120 to 240 volts. and a lot of the components are the same, Its also the same with matching the mosfets because if they are not match they will blow pretty darn fast.

Greetings from Russia. thanks for your videos. please continue , very interesting

Just started to watch your video's which are cool. Little bit of advice if not already provided. Rather than cooking the board when fitting the zener or cap etc it would be much easier to use a soldering iron with a small 1mm tip, hold the component in place then solder each end in place with no burnt fingers or lost components. The hot air gun is the ideal tool for removing or replacing ic's etc but not necessarily for single components.

don't pick up the 400 deg board. good tip! lol I enjoy your work thank you.

Great Job man.

excellent vid sam! xx

Is there a website for your repair shop an do you sale refurbished amplifiers an subwoofers?

good worke man keep them coming

Bro,your vids are super informative, thanks for all the info,keep em comments. You could start charging for these videos bro 😂

Good content, subscribed. Very useful for Invertors, which is basically a class D also. I would comment a bit on your soldering technique, but ... as long as it works for you - it's fine. One question, what are the two thick wires going from supply to amp section for?

@barevids

Audio output. It takes it from inductor output to speaker terminal on the case

Yes, we like the videos. Instant subscribe.

Nice repair video. When you say high side and low side drive, do you mean positive for high side and negative for low side drive?

Nice dude,,I think you do a fantastic job at amp repair ... Is any of the sonido mask amps you have repaired for sell?

Like the Video well explaine. But where do you order your FETS?

Awesome, keep up the vids.

*puts hats and sunglasses on mosfets*... yeah, they are getting cooler

Your teaching an old man new tricks. Back in the 80's I repaired a few class AB amps (Rockford's, PPI to name a few). These class D amps are a whole different animal, to me very complex. Have you ever worked on a MTX Thunder 7801? And if so what is your opinion of this amp?

Yeah I like these. It's odd they still use those 4 channel mos driver protection boards. Wouldn't it be more hardy to do a single H/L mosfet driver with the same protections and just run all 8/10 power supply mosfets from that? A single purpose built driver would have no trouble driving 10 power fets through their gate resistors at that khz range.

what kind of capacitor is the orannge looking one on the side u working on

What do you call the circle thing with wires wrapped around it? And can that make no sound come from amp?

i have an sound stream 1700 d tower series i recently got but i still do not know if i can fix it how would i go about talking to you aka get a quote or maybe. figure out how much shipping might cost across the pond for you to fix plus parts and labor

hey was the max voltage that scope can measure?

great content 👍

man i noticed you have allot of speakers my question is would you ever get rid of any by any chance? i cant afford any decent speakers and would love some good ones for cheap tired of cheap duals and sony

Muy bien!

Love it

Bro I have a t2500bdcp my transformer is buzzing input filters are fat and 2 blown mosfet what would be blown in ur opinion I know fosgate has good isolation

Do you ever repaired a class D amplifier with scratched off IC marks? This would be interesting!

@barevids

6 жыл бұрын

yes, all the time! Most boards are so generic, if youve worked on enough of them you know which ICs they are anyway. However, for an amp that is not generic and brand specific, like a soundigital which came into the workshop recently, there are no other amps with this same board and so if the ICs are scratched off, its almost impossible to repair as there will be many similar IC models that appear to "work" in theory in circuit, but only one model will actually behave as intended. And without knowing what that is, you have no chance. Sadly Soundigital only release this information to certified SD repair centers.

Hi. Sam I live in Barbados have a Genius 8000w amp stop working going into protection can I post it to you

are those driver boards switchable between amps ?

@barevids

Yes as long as the driver boards are identical. Many amps will use the same or similar boards and opt for a standardised driver board.

Residual current from static or inductance from another nearby part of the board can build up on the gate leg if there is not a pull down resistor. Electrons grouping on a conductive surface and stored as electrical potential energy are generally referred to as "current" - eg. "for an electrical circuit to operate *current* needs to flow"

Yo.... Do that kind of video & after repair.... Plz do a subwoofer demo...

Flex is what blew my amp took only 2 months to do it.

Another one down a whole bunch more to go! Lol

I'm an electrical engineer, and I was really excited because I stumbled upon your 1&2 video of that long amplifier repair. I was really looking forward to watching your videos while working, but NOT if you're going to be dropping the F word here and there. I'm got small children and I don't want them to hear it either, besides the fact it's very unprofessional. you lost me as a subscriber. Sorry.
