Perfect video!!!i learned a lot from your videos and tutorial.thank you Man!!!

[@ellensburgamplifier]

Thank you and always happy to help others where I can.

Great video Todd like always keep up the good work sir very educational I really appreciate your videos 🙏👍

[@ellensburgamplifier]

Thank you my friend for the support!

[@strictlyamps820]

Another great video Todd

[@ellensburgamplifier]

Thank you Cliff. I get so many emails with people fixing their own amps with just DMM's I figured I would show that reading may look normal and OK until a scope is hooked up.

Todd, i have a Taramps MD12000 i’ll be shipping out to you this week!

[@ellensburgamplifier]

Most excellent! Is this a warranty repair or a private repair?

[@luissantamaria3941]

Hello. Where can I get a replacement capacitor? 648 k 250 t594. The blue ones.

[@jhititup]

I have 3 of the 8k amp with offset voltage problems. the 1ohm 8k passing 60v dc out the speaker line and the other 2 passing about 26v all 3 amp is playing. I am trying to hard to find a service manual to fix these amp.

[@ellensburgamplifier]

DC offset issues are an output drive issue or there is a resistor or two out of spec in the DC offset circuit. Sometimes a quick brief nondestructive output short will damage the offset circuit. I am under an NDA with Taramps so I am unable to provide schematics.

[@STACKHOUSE25ify]

hello, would you have the electrical schematic from the module?

[@ellensburgamplifier]

I do have schematics for Taramps but I am unable to distribute this information. If you contact them they are the best at helping people out.

[@Patrickmiller-k9j]

Hi I need help my brand new amp went into protection mode then turned off and will not turn. Its a Tharamps MD8000.1 1ohm am.

[@ellensburgamplifier]

Sounds like the common IC9 failure. This IC is responsible for turning the amplifier "on". If it is new and recently purchased you may be covered for warranty repair. www.ellensburgamplifier.com/request-a-quote if you are interested in a warranty repair.

[@denistoukalenkov]

Hello, what supply voltage you are using? dc offset varies depending on input voltage, 12v and 14v shows different dc offset so in which voltage is correct to set zero? Thanks!

[@ellensburgamplifier]

I set the DC offset at my 12v bench and recheck at the load bench that runs at 13.6v. If this is your amplifier then I would set it at the voltage you run your system at.

[@blckds3085]

Hi. My names Dani and I have a taramp smart 3k that's going in to protect when I turn the gain up. After turning it back down and turning the amp off and on the amp comes back. Could I these get this issue fixed.

[@ellensburgamplifier]

I do have 2 questions. How many times is the LED on the top blinking when it goes into protection? What is your connected load (the final resistance at the speaker terminal)? I would be more than happy to repair the amplifier if there is an output issue.

[@blckds3085]

What zeeners are they? Having a hard time figuring out what value they are Been trying to learn a little bit of this and my MDAK got fried when my wife was in the truck I have a few blown mosfets and zeners but having a hard time knowing what they are I have someone with a Blue line I think and some with a black line.

[@ellensburgamplifier]

They are 15 volt zener diodes. The ones with the black stripe are 4148 signal diodes. I would caution when you buy zener diodes they may also come with a black stripe.

[@jeremysparks4570]

Ty very much. Are they using secret parts? Been trying to decode the 4115 p050 dh40?mosfets can't really find anything on those particular ones.

110 $ each SI8244 drive IC? Please clarify? nice video though..

[@ellensburgamplifier]

They were high priced during the pandemic when you could not find them. They are now back down to a somewhat normal price.

[@FrankStPeter]

And just making this point to the Young Bucks that are just getting introduced to the audio game what it used to be and what it is now, I paid $800 for 800 watt amp and got 20 years out of it

[@ellensburgamplifier]

Oh ya, nothing like amps from the late 80's. I remember drooling over the power 1000 but could never buy one with my $4 an hour job.

[@brick2077]

What causes the buzzing sound from the amp? I hear it at very low volume. Could it be a filter capacitor ?

[@ellensburgamplifier]

If it is from the amplifier itself then it is a noisy winding. If the sound is at the speaker then it most likely is input noise through the pre amp.

[@brick2077]

@@ellensburgamplifier I hear through my subs and when I roll the bass knob up about 2/3 the way it makes the subs sound like it's getting lots of power and then not enough over and over but when I roll it up full turn it just gets tons of power with no problem. What causes it to do this?

[@ellensburgamplifier]

@@brick2077 Sounds like a bad potentiometer in the control knob.

[@brick2077]

@@ellensburgamplifier well I also thought the same but I put in an older amp using the same bass knob (slam panda 🐼) and it does not do it. Btw it's taramps md8000.1 1 ohm wired at .5 ohms charging at 16 volts at the alt. 350 amps and lots of lto lithium. Rca volts are 1.65

[@ellensburgamplifier]

@@brick2077 Be careful with 16 volts. IC9, the remote turn on IC can get damaged with high voltage. I do have a few videos on the 8k. It may be an amp issue but again I would have to diagnose it to have any answers.

[@ThatsMrMark]

A lot of time the reason the power supply fails with no signs of any other damage is simply due to the lack of available electrical current and or battery reserve. This in turn places a tremendous strain on the amplifiers power supply section/s resulting in ps failure as I stated above. Premature clipping also is a pretty major factor when it comes to the lack of electrical. This is one of the main reasons why the first question that I ask every single customer is, what does his or her electrical consist of entirely, from the front to the back and everything in between.

[@ellensburgamplifier]

Good to see you here Mark! I hope all is well and I do thank you for providing this information.

[@ellensburgamplifier]

Agreed and reverse polarity is also one I commonly see. Another good one is seeing 4 gauge wire left in a 0 gauge terminal.

[@FrankStPeter]

I agree with you on the sheer numbers my friend, I agree with you that they are one of the better for the money that you pay,,, but when we say reliability in the audio world we really mean to say ABUSE,, and you cannot abuse these amps,,, it doesn't matter if it's a sound digital Ground Zero Tera amp sfb's all the Brazilian copies,,, unreliable,,, my hcca just blew up after 20 years of abuse,, I bet a shiny quarter that says in 20 years from now you will not find a taramp that got used every day still functioning

[@ellensburgamplifier]

100% correct! The automotive audio world is most people will see what a system will do. The SQ end of the audio world is something that is becoming part of the past. For instance, I have an Audiofrog 150.4 here claimed to be a top-notch SQ amp but I do not see anyone paying the price for it. they would instead put the money into a Pitbull 20k.

[@osoriotutoriales]

IC Driver ,mouser is cheap price

[@commonsenseisdeadin2024]

Biggest issue I believe is that the amps are too cheap (Money not quality) and these people are not supplying it with sufficient electrical.

[@ellensburgamplifier]

Hi good to see you again! I see this issue mostly on the 8k and 12k amps. A little more solder on the traces prevents this issue from happening again. At least this is what I am seeing. People may underestimate the potential power of these amps due to their size. Parallel up a bunch of IRFB4127 or IRFB4115 transistors (depending on the ohm version) and you have a ton of potential pulse current handling.

[@electronicengineer]

Hello Todd! After having watched you working on quite a few of these Taramps mobile audio amplifiers now, I must proclaim; the copper cladding weight used by this company for their printed circuit boards is insufficient. I have seen you struggling with repeated circuit board failures on the Taramps amplifiers which, from strictly a printed circuit board design perspective, is extremely excessive. I am coming at you from thirty plus (30+) years of hands on, mobile audio amplifier repair and modification/alteration experience and I cannot say, under any circumstances, that the Taramps PCB failures that I am witnessing via your KZbin videos can be deemed acceptable in any way. This is to say, in my opinion only, that these Taramps PCBs are utter and complete, under-designed, junk. Fred

[@ellensburgamplifier]

Yes, I do agree that the traces are too thin for the amount of current that can pass through these boards. It is always in the output section and I am sure with enough claims they will change the thickness of these boards. After I do my make-over on these I never see them come back with this issue. Thank you for the channel support!
