Thank you so much for fixing my old-school phoenix gold titanium 600.too! I can’t wait to throw it in the car! I’ve carried that amp around with me for over 10 years now I’m glad I finally had someone able to fix it.
That's the same thing happening to me now Todd alot of Amplifier coming in Sunday is mostly my repair day great video like always Sir keep up the good work nuff respect 👍 🙏 🙏
Good work bro. Irfb 4115 is great. I have a suggestion for you. Always tell the basic information about any amplifier that comes to repair. For example, rail voltage, output power, which ic used to drive supply and audio section, Mosfets in supply and audio section. It will be a great help for all bcz we will know about different topologies and parts. Thanks again for amazing videos sir. God bless you
I do apologize for the delays as the end of school for the kids and them getting the "bug" has made this month very difficult. I promise I have not forgotten about my subscribers!
The charge is dependent on the damage and what needs to be replaced. I don't charge by the hour but rather by the job. If you are interested in estimated prices you can contact me at www.ellensburgamplifier.com/request-a-quote and I will be more than happy to go over the details.
Hey thank you for the great video! I'm repairing an 8k now and have replaced the mosfets and a couple zeners on one of the drive sides but when measuring the transistors between the output and powersupply section I'm seeing the gate and source are shorted to eachother (on the U1620G and U1620RG). Is that right? Appreciate any help!
Those are rectifiers. I would look up the datasheet to understand how that component is made. There is a common cathode and a common anode rectifier. (there are also doublers but not the case here)
@@ellensburgamplifier thanks a lot for the quick reply! I tried repairing this twice now and had the mosfets pop both times but I never checked the zeners so I've replaced them too as well as 1 or 2 3.3ohm resistors but am honestly a bit nervous to try powering it up. Do you have any other tips or recommendations of things to check? The board I'm working on basically had an identical failure as the one in this video.
could you tell me what the specs are for the 2 resistors on the bottom side of the board that go from the left RCA input to RCA ground and then the right RCA input to RCA ground?
My buddy at taramps sent me the schematic for the md8000.1 and the bass 8k but looking at the schematic I couldn't tell if that was on the back or not because it didn't really specify but thanks for your help
i have a bass 8k an when I power it up the fans come on full speed and stay that way aren't they supposed to spin up and then drop down to low idle or should they be off until the temperature goes up enough for them to come on?
There are very few MCUs that will drop the duty cycle to 50%. I am not sure, but I think they have been playing around with dropping the duty cycle to 50% on some boards to see how well it prolongs the life of the fans. The best answer is they run 100% unless it is a Smart line of amplifiers.
So, just curuous (and asking the community): What's it cost to get an amp repaired and what is it that drives you to pay for a repair instead of a replacement? It could be that I'm not into these big, bad boi amps so if an amp dies, I could just replace it (also, I haven't had any amps die on me that were worth repairing).
I will use a Taramps 30k for an example. You can buy a new 30k for 3500. Now let's say the power supply board had a complete meltdown where nothing could be saved. I can replace that power supply board for a little under 1k (amplifier splits in half). Now if the output failed then I just replace the transistors, Zener diodes, and the drive IC for under $500. From there you can see that you will save more than 50% by having it repaired compared to buying a new one. For smaller amps, anything under 60% of the retail cost I would consider to be repaired before buying a new one.
Hello I have 2 subwofer one sound stream at 600 watts wired at 2 ohms also a Kenwood at 4 ohm 400 watts rms an want to wire them to a 2ohm stable amp but I don't want to limit the current to the 400 watt sub so it doesn't over load while the 600watts sub is it at max how do I do that do u use a resistor? Thankss
@@lolo-gv3nl What amplifier are you wanting to run? 2 ohms is not a large load to an amplifier and I would know more if I knew what amplifier you are wanting to run as some do not make the power that is listed.
@@lolo-gv3nl If you are able to wire the soundstream to 4 ohms then you can parallel the two subs (4 ohms parallel is 2 ohms) and you will be A OK to run them with that amplifier. I think you will run right into clipping before you have to worry about wattage. I could be wrong as I do not know what the rail voltage of that amplifier is.
Defacing a Smd transistor can you imagine they just want us to keep buying amplifier and not repair them and some of the amplifiers are so expensive and sometimes it's a little smd that is the problem and because of Defacing them we can't do a simple repair that's so unfair to us I hate when they do that acting like we are there enemies and we are the one buying from them
Trust and believe me when I tell you about the soundigital thing, they're not even going to respond to you. I went through this with soundigital years ago, and for this exact reason simply the way they handled the situation or lack thereof, I don't work on soundigital amplifiers at all. I won't even touch them. Shane, or maybe Sam could give you a little bit more insight as to what goes in those particular spots.
Thank you Mark. I got their email response today. It was quite interesting. I can say if they ever ask me to work for them I would have to politely turn them down. Always good to see you here! I had a Taramps board in a while back that had your initials on the caps and thought that was pretty cool.
@@ellensburgamplifier yes sir man🙂 There's a couple things that I do so I'll know that I worked on that amplifier, how many times and what I did to it.🙂🙂🙂

Thank you I hope you can enjoy it for years to come. Also thank you for the channel support!
Car amps are the BEST for a stimulating driving
can u help me the service manual of the amps I am getting 60v dc out of the speaker line no output transistor damaged.
I am bound by an NDA but you should check the feedback circuit where the potentiometer is.

What's the main supply voltage of this amp....and what is the output MOSFET number...thanks in advance
Hello sir. Im waiting for your videos, where are you nowdays? Why are you not uploading videos?

They are 100 ohm resistors in that location.

What glue do you use to beef up the hold and stability of the inductors ??
Gorilla Glue Clear Grip is hands down the best in my opinion as it is tough and solid yet can still be removed.
