Hifonics Brutus 3000 Watt Surprise Mess Inside

[@jbell0507]

Thank you Todd my salt 8 sounds better than when I first got it

[@ellensburgamplifier]

Excellent! Keep it cool and not overloaded and it will run for a long time.

Thank you sir

[@colinwagner2744]

Dang, that looks like a nightmare. Hopefully, if u do the repair, I wanna see a video of the repair

[@ellensburgamplifier]

I will keep that in mind and maybe go live with this one.

Hi Todd Thank you for replying to my previous comment. I am slowly watching the videos of your channel Now I have a problem that I am asking for your help. I have a class D amplifier called LeoDio Lc1000.1 I completely understood the switching power part However, in the amplifier section, two optocouplers called 6n137 are used along with 4 transistors, which then reach the gate MOSFETs. There is also a 555 IC next to the input op-amps, which has no frequency in pin 3. But one of the op-amps has a frequency of 129 kHz in base 1 In the control card, there is an IC called "mz9t040" which is written in the first line with the number "3l9" that I don't know what it is at all, and it has no data sheet. In the control card, there are two ICs with the number "74hc02" which are NOR gates I don't know how this circuit works. Please, if possible, give an explanation or make a video for this amplifier. thank you

Unfortunately, I am not familiar with that topology. In most amps that use the HC02s have a comparator with a Tl072 that creates the square wave. They may be using the 555 for the same purpose?

[@nimaesmaeil9318]

@@ellensburgamplifier Hello Thank you for your answer No, there is no frequency available for 555. Is it possible that it was used to create negative nutrition?

[@ellensburgamplifier]

@@nimaesmaeil9318 I do not know that amplifier circuit but if you ask Perry over at DIYaudio.com I am sure he can assist you on this one.

Hi Todd 👨‍🔧🥂

[@ellensburgamplifier]

Hi there! I hope all is well and I than you for dropping in :)

[@artart6357]

Do you repair amplifiers? I have the same amplifier that needs repair

[@ellensburgamplifier]

Sure do almost 7 days a week the irons are on. www.ellensburgamplifier.com/request-a-quote

[@cartycartyamplifiersalesrepair]

That's a really beautiful board too be damage like that 🤦‍♂️

[@ellensburgamplifier]

Agreed, I am still debating doing a live stream repair of this. It is repairable, I just would not be able to charge the customer for this as it is NETR.

[@cartycartyamplifiersalesrepair]

Hey tell the guy for that Amplifier to put it up on Ebay I would need that Amplifier to buy

[@ellensburgamplifier]

@@cartycartyamplifiersalesrepair I think he does sell his amplifiers on Ebay. I will see what he wants to do with it.

[@SavedByGRACE360]

Not a good idea to put amps under seats. Spills = disaster

[@ellensburgamplifier]

Agreed! I had an amp come in that was covered in the carpet spray you can get at car washes that people spray under the seats. Liquids and amps do not mix.
