I have a Rockford Fosgate p4004 and channels 1 & 2 work fine but if you put any load on 3 & 4 the amp goes into protect. Can you hopefully give any incite on what's going on with it?
Hi, I have 2000w Kac-ps917D Kenwood amp as soon as I increase the volume it goes into protection mode, after troubleshooting found out that there is continuity between +ve and -ve power terminal checked the caps and fets everything is fine, any idea what should I look for?
Do you have a shop or work from home? I have a Denon DCA 3400 class A amp probably older than you that decided not to switch on after a break. Checked the fuses then my knowledge run out. How does one get in touch or is this a hobby?
Hello and good day , so I been watching your channel for a long time now and I will say it's amazing what u do . That being said I was gonna ask u if u would happen to repair my helix amplifier A4 . I have 1 channel only other 3 channels are not functioning. No sound.
I’ve been following you for years now and feel as though you’re the best at repairing amps. I want to send you an amp to fix it. It’s an Audiopipe apmn 2000.1, it more or less a Skat Rp 2000. I’m not really sure what happened to it, it blew a 250a fuse and then it just stayed on with power and protect lights on and they stay on. I’m 100% ok with the shipping and cost to repair, would you make a video on it too? Please let me know how I can get this to you. Thanks so much Sam. PS in in the USA too. Thanks again
Hey Sam, a channel called Stereo Mojo is experimenting with amplifier clip lights compared to the DD1. He's got an oscope showing the signal. Maybe you could explain what he's seeing? I'll add a link below, but youtube might delete it. The video is called "More clipping and distortion testing".
Hey Sam! Love your vids! I saw you modified a Taramps Smart 3 to remove the subsonic filter. Do you have a video on this process? The fact that Taramps drops the low frequencies in the preamp section kills me... We need to know how to get around this. 😁 🙏
Sam, can you test an idea that I had recently about a perfect place to play bass with out lose too many decibels across the room? Like you made in the Boom Or Bust that is very small compared to the real world. Imagine two isosceles triangles united by the bases of both, if the subwoofers is placed at exact the center of that unified bases of both triangles, everywhere in the room now have almost equal decibels level, because as further from the center the sound wave travel trough the legs of the triangles, less space it has to lose SPL as it is approaching the most acute angles of the triangles. Just have to be careful about where to place the doors and windows. I imagined the windows being very close to the roof so the walls would reverberate better the bass without the glass causing comb filtering, and the four symmetrically placed doors would be very close to the middle which is where the DJ Controller and the speakers are. The speakers have to be in 360° so everybody can hear in front of them. I had this idea watching DnB Allstars 360°.
The bass frequencies bounce around and you get certain frequencies that get reinforced and some get canceled. This causes peaks and dips in the frequency response.
@@JasonWW2000 Thank you for the reply! But this happens in a rectangular room too and a lot worse in a square one, so a double triangular room will be better than a rectangular for sound waves.
@Barevids- I really loved your Boom or Bust video's. Are you getting a different size, or higher X Max capable driver to test, in the Boom or Bust series? Would really 💖to see this series again, they were so fun to watch!
@@barevidsThats so 😢 I think if more people knew about that series, it would take off. I used to love your car audio, bass testing, and showing box/impedance rise, and how port tuning effects where the most rise happens. I think since you have done more amp fix/repair video's, those type of viewer's were not interested in the Boom or Bust video's, as much as if all your Bass head viewers from the past, would have known about them= would have been a big hit!? To be honest i have only seen bits and pcs. of your video's about amp repair's. I just so happened to see what you were up to when i stumbled upon the Boom or Bust series, i thought that was your best video series EVER! I truly believe that if more Bass Heads seen that series, it would explode in views. Thank you for taking your time to comment💖
U are litterly a amp fixer guru... 🙏❤️💪 job wel done .. much respect..
Fault finding is a specialism itself within the electronics industry. Nice find!
I also need the schematic
We're could I get some of these diagrams??? If so 🙏.
I also need the schematic
👍🏽 another great video!
Wild that it took all of that diagnosis just for a poor solder joint!
Nice video man
You are actually becoming an inspiration for me… and I don’t get inspired by others that easy.
Awsome as usual wish u lived in the states such great work
What would cause only (1) 250v1500uf capacitor to swell ?? Also the amplifier is fully functional it’s been been hibernating sense I found this issue.

That was a good find wow keep up the good work Sir 👍🏽🙏🏽
LOL funny enough im using a tl494 for a psu for my uni rocket intruments
Hey it's been a couple of weeks since you dropped a video, just wanted to check up on you?
dang all of that drama because of one bad soldering job i hop its an isolated case
I have a memphis audio amp that seems to clip in and out and im not too sure why. Could it be a resistor or something inside?
Where can I get held with my amplifier, would be really appreciated
I need to find someone to teach me how to diagnose these issues.
Boom or bust ep 16 tesla valve box?

Blown power supply fets probably due to blown output fets.
We demand an amp testing Spotify playlist! 😂
Hi bro , what's is q1a mosfet in Chinese 3000 amplifier? 075n15n ??
Or maybe it's 01A ?and what's mosfer part number

Hi sam i have a taramps MD 8000.1 1ohm amp that will not turn on can you help me with it please i wanted to know if you could look at it
If you're in the UK yes
Well impressed

You said amplifiers can go into low voltage protect. Can have a video on this subject so I can save it in my archives? Thanks

done thanks
FIRST! Mind blowing as always Sam!
Do you uave a music playlist if you do please share 😩
Is it ok if i read voltage on top of the cap where there is cross ❌
hi Sam, do u have schematic for MC1 and SI Drive connection?
No i don't really use schematics mate
@@barevids any idea what is the MC1 details as mine all skratched and i couldnt find in internet the proper part numbers
@@basshead100 I don't know what you mean. Send me a picture to barevids facebook page
Oh the issues we find!
Price to fix tarramps MD8000 ? Stuck in full output
