This is excellent information, particularly the insights into troubleshooting the audio driver's expected performance and setup. However, I'm uncertain about the section at 3:31 where it's suggested that part of the circuit uses IC5, which is a 1678 Op Amp, to generate the ~25V suppling the 7812. I might have missed something, but I'm not clear on how this circuit would be boosting the voltage. To be fair, I also couldn't identify from your camera angles where this voltage generation might be occurring. I don't see any inductors capable of such boosting, aside from the larger, more obvious ones. Fantastic video overall! The feeling of okay....well it's working with the uneasiness of not exactly knowing why. Creates those potential fix returns.

Interestingly enough, 30% of amplifier failures is due to a piece of cable strand creating a short somewhere.

Sometimes applying heat to a transistor or cap can make it work again. Hope it continues to behave itself.

What is the difference between a professional and a hobbyist? The hobbyist loves the phantom fix. lol

The phantom fix is like Schrödinger's Cat: something is fixed until the issue come back.

So, as for an ultrasonic cleaner: Stainless steel chaffing pan and a bunch of piezo elements, all connected to an amplifier capable of high frequencies above 35khz, driven by a frequency generator that can put out 20-25 volts continuously. Fill with deionized water, drop your board in and turn it on. Actually, a phase change humidifier will do the same thing as this, but it's too small.

Sam,, you are a great instructor! Thanks for the videos, you have thought me alot. Keep up the good work 👍

It's amazing how some amps survive in some people's cars with all of the dust and dirt I see on them. And it's even crazier because the circuit board is upside down when the amp is mounted normally, and you see all of the gunk that gets on the boards. 🤯🤯 It makes me cringe just seeing all of the mess that gets captured by the heat sink compound. The ones with the dead bugs and spiders makes me laugh though 😆😆. I be like, WTH!? Get out of here.

Sam have u had a look at the big boss series from taramps? Curious what u think of them. U did a great comparo of a bass 5 vs smart5 or maybe they were 3s. Anyway they the big boss series is upgraded internally??

I have a Taramps DSP 3000 that does nor turn on ( no loghts tuen on either and no sound) . Did some checks and noticed mosfets from the powersupply shorting when checking with my mutimeter. On the board it says IRF1404 but the mosfets that are installed are csd18502kcs. Don't know if they have been changed already or not ( second hand amp) . Should i buy the IRF1404 csd18502kcs. Can't find both locally

Have a quick question about the fans in a taramp Amp witch way blows in and witch way blows out

👍👍

Yep, I hate that. Always makes me wonder what the hell was the original problem? What did I do? What did I do different when it suddenly worked?

What do you think about this version versus md or hd version? Only the crossover is diferent?

Hell I had a Rockford Fosgate Prime series Marine amp power up, but produce no power, come to find out the main power torroid had a leg that was not all soldered at the factory to the main board, but yet some how passed QA. I soldered the leg back to the board, and a booming it went till I sold it!~

The suspense is killing me !!!!!!😄

I keep missing em lol, better luck next stream

this wasnt a stream buddy, lol just made a video

Have you thought about turning all of your video text into a book? Like an amplifier repair book of sorts? Kinda like a text book for specific amplifiers repair. I'm sure it would be a ton of work but ai could help so much

Nah like you say it will be so much work and no one wants a book these days.

Conductive carbon dust should not be underestimated. I have seen 8 computers from a diesel repair garage killed by it, all with weird intermittent faults, washing machine controllers where carbon from the wearing brushes has caused a flash-over due to high voltages on the board, and even a vacuum cleaner speed controller killed by it (henry dual speed type). If you are honest with the owner about the 'repair', they will likely understand if it fails again. Best keep it away from diesel (exhaust) fumes in the future.

Ok i got the bass 8k i am running it on 4ohm with 1 csb 100ah battery in my car and got a set starsound 5212 compition subs tell me is the set up with one battery ok or do i nees to put a nother battery in

Is there a crack or a piece of substance on the circuit board?

Hey Sam have u laid ur eyes on the taramps big boss 3k 5k 8k ? Big big power amps.

@@barevids they are simply nuts mate they are rated . 5 to 2 ohm at 3k and at . 5 they do like 8500 RMS. They also have led lights everywhere on them that u can control the 3k big boss goes for around 300 here in the US .

Anyway you could help me diagnose my Helix P2? 😅

I hate it when I chase my tail on a board just to say what the heck at the end.

You could run it for six months and it would still fail within a week for the customer.
