You're one of only a couple people who do an AMAZING job at explaining what youre doing while youre doing it! Keep on doing these amplifier repair videos!!! Youre helping so many people out!
você entende inglês, sabe o que ele estava comentando sobre o amplificador brasileiro, bom ele dizia que e uma construção terrível, um transformador desse tamanho, com mosfet muito pequeno, são fortes porem esquentam muito uma carcaça de alumínio pobre e os controladores micro chip do lado do transformador foi muito frustante ele disse, ou seja falta de organização em termos de durabilidade as coisas brasileiras são feitas para lasca o brasileiro sempre foi.
@@Lexengenheiroelétricista máximo respeito Mestre. É o que venho dizendo esses anos todos a alguns amigos do som automotivo. Nunca entendi porque transistores tão pequenos pra suportar tanta CORRENTE, no amplificador que tem 4 fet na saída, o correto seria 8 😉. Carcaça fina DEMAIS, cooler em locais não estratégicos.
Thank you soooo much for doing this video. That helped me so much on a hd 8000 repair. The 8000's board was almost identical. I replaced all the blown fets and nadda. I just replaced the drivers and bingo. Thank you for the videos. Very helpful.
Two top tips; you can re-moisten solder paste with isopropyl alcohol, messy job though, wear gloves :) Also you can buy SMD discrete component "sampler packs" where you get a strip of about 20 of each value in a neat little organiser, damn handy for rework jobs.
nice amp, its a pain in the ass removing all the dead mosfets...it bothers me how you don't clean the board. you should always clean the old solder. i have repaired amps for years. trust me wipe down the board prior to reinstalling new components and use a power supply with a current limit just in case you accidentally short circuit any leads. thanks for sharing...damn you remind me of myself in my basement late nights...lol thanks!
Ten thousand Watts at 12 Volts is 800+ Amps. Yeah, right! Bloody class D is only fit for use in a car, I wouldn't let it anywhere near a decent HiFi system. Good work and thanks for the vid.
i plan to start designing my own power supplies and class d amps in due time when i get a scope, function generator, and a bench power supply one issue with making these things is the high frequency switching tends to jump gaps in mutually coupled lines which can lead to tons of noise, other than that the architecture is really simple, even more simple than class AB There's a diysmps forum that has a ton of useful information too, including a SMPS flyback transformer calculator program that is free
Technologic have you thought about building a power inverter? they share components with amps. I been wanting to attempt it. everyone says I'm crazy. just buy one. I also want to build a DC motor speed controller. for a EV project. about 600 amps at 72 vdc is a lot of power to play with. but I have no experience and self taught. I use you tube and Google to help learn . I'm a little old to go back to school.
youtube is great for both of you whatever your planned budget...plan the money and the TIME!! 6 months to build something is expensive on time!! out rubber gloves on and water safety and capacitor safety... i have been electris shocked and its not cool!! and can be deadly!!
I was wondering if you could help me identify a problem with my amp. I have an hd 10k like in the video (2ohm) and it decided to just go into protect. No sparks or smoke. Wasnt even overheated. And yes, I removed speaker wires and rca's too. Still in protect. I popped the back off to see if I could find something burnt or broke, and theres nothing. Im not a circuit board repair man but I cant afford to send it to be repaired or to replace it.
@@barevids As silly of a question as this is, but do you have any videos demonstrating this? Like I said, I'm not a motherboard repair guy so I have little knowledge on what is what and where.
@@barevids So, Ive torn into it a bit. After some testing I have concluded that the mosfets are fine. But, on the power supply side of the board, the drain and source spots on the board for the first 2 sets of IRF1404 fets (3 fets per set, 3 sets per left and right) on both left and right, are making contact.

Hey, My taramps DSP3000 blew the output. I replaced the mosfets and the amps works, but if apply 14volts or more, it goes into protect. Before it blew it had no issues, and would handle 14.4 as the amp says max 16volts. Do you think this can be caused by the ICs? Also how did you find the schematic? I couldn't find one. Thank you for your time.
Do you know what is the number for the drivers of the power supply for a bass 8k. I have an amp and they burned to a crisp, so I can't read the chip. Thanks if you can help.

Hey bud can you tell me something I have a taramps 8001 I am getting power clip and protec on all at once fan are on full voltage on the rails no sound what do you think?
Can you repair my Taramps MD 12000.1. It rubbed against a medal bracket in my car and started popping then caught on fire and I really mean on fire(but internally). I unhooked the amp and saw where it caught fire and saw smoke residue. I tried hooking it back up and heard popping again but it wasn’t rubbing against anything this time but the amp displayed on and protect light.
Have you ever repaired a Rockford Fosgate Power BD1500.1? I had one repaired and for some reason it's not putting out power at Powers up and not in protect and wondering if you could tell me what to check? I don't see any burns on the board and no fets look Burnt. The last repair the man had to fix the gains and output fets and he's a professional at Freeman car stereo a Rockford Fosgate repair specialist. I sold the amp when working and dude hooked up a wire tester to the output and said it's Dead? Could he burnt it up hooking up a DC light tester to the output? I'm sure Jason Gibbs at Freeman car stereo did a great job on it but I just don't have the money to send it back to be looked at again. You have a video to recommend to watch to troubleshoot the problem?
Hey barevids, do you think on making tutorial videos on how to calculate a box, how to tune it ect,... , and explaining in detail (with those dual coil subs also). I saw a site in my country started selling DDs and i'm planing to be a RL 612.
I have a question if you could help or anyone else. I have a old sundown sax 100.4 and seem to have ran into a small problem. Only two channels seem to be producing sound while the other two are not. Specifically the bottom two are working while the top row is not. Any idea what it might be?
Hope you casn help me. I have a Taramps bass 12k That blew at some point. All the Mosfets has been replaced. But when I power on the amp, it runs the startup procedure and then it gives out 32Vdc in the speaker terminals. What can be the cause of that? Really hope you will take the time to help. Best regards Michael
The power transformer is not a very good design. The wire strands are too thick to support proper current flow due to high frequency skin effect. Also the cross sectional area of the primary winding is way too little, you need much more paralleled wire strands. I agree that Taramps does not put enough output and power supply MOSFETs, or use even better MOSFETs with lower Rds, probably a cost issue.
My taramps smart 5 bass stopped working on me and won't turn back on. I wasn't playing it for long and i had it on low volume when it happened. I have the amp turned up less than half way, never clipped or protection light never came on. I have it on two digital designs 710's. I have good electric. Mechman 400, two xs power titan 8's, dual runs of power and ground. Amp grounded to battery. frame, chassis, engine, and alternator ground. My fuses under hood are not blown and I checked with volt meter at the amp, i have power at the amp and remote wire has power. Any ideas what could be wrong? I haven't heard of anyone having problems with the smart 5 bass yet.
Sam I sent you message about needing help with a amp. I have a taramps hd 15k. It blew a rail cap. just 1. and I replaced it. the amplifier never went into protect. anyways after replacing it and powering it up out of the board with a limited dc power supply, I notice the output fets start to heat up in uniform. this is with out any load, just limited power up. the waves look fine. its only pulling around 5 amps at 14.4v at power up. Is this normal for these fets? is it because im using a limited power supply and its such a large amp? did the 10k do that. it has the same output section as it. what do you think?
I'm looking at getting an md 8000.1 2ohm. The price you pay for that kind of output at 2 ohms seems super unbelievable. You mentioned the full range technology just "isn't there yet". What do you mean? Bad quality? Unreliable?
Hey bro just need a little advice I have the same model but one half of my output transistor blow in the output section replace it with driver IC. amp power on ok but when I turn up the volume there's a loud hum and amp go in protect have you ever experienced this problem.
I have a question about a Lanzar opti 2k, ic by the driver board was bad KIA 393p ic, I replaced it and still in protect?? Any suggestions on what else to check? Input and output FETS are all in spec, two resistors were bad on output driver card, buddy of mine had it in his car forever, power wire at battery corroded, and he thinks dead shorted and blew fuse. But amp still played for another month but kept getting louder fan and like a whine/screeching noise. Took amp out, I looked at it and now in protect mode. Thank you sir any help is greatly appreciated
Sounds like more issues in output drive circuit. Determine why it is in protect, as you power it up look for rail voltages in the wrong places on output mosfet pads and go from there.
I figured it out buddy, thank you sir for your help!! It was loose pins into actual drive card from board upto driver card pins were broken. Now gotta find parts
i have an amp im working on that looks far worse than yours, how do you go about cleaning a board like this? sink sprayer and then followup with isopropyl?
The TC35 had a double connection of solder creating a short. You can barely see it at 3:04. It create a nano resistance in diode 448A towards the IC which causes a surge in cap R598. It wont blow it out, but reverses the vacuum connectivity, if you will, and the solder reacts as a negative magnet of sorts making the thermistors and IC's give a drive wave of negative 5 plus 4 (obviously not adding up to 1). Next time, short the PC68 Cap and leg 2 and 6 of the 1I96 Stationary board and it will bypass the reaction board. You will get less Bass but the treble will be amazing. Also, This board was made in a factory in Nyflanigan during a drought where fish were abundant, but deceased. So, Fish oil caps from this region are highly suspect to fail. You will smell an odor if the caps pop. It may smell like your urine. Which means you need to drink more water.
@@barevids hey boss I appreciate your repair vids great stuff I was wondering where I can purchase the current sensing ic ir25750 looks like it’s obsolete or is there a replacement part I can use , I would appreciate it thanks
What’s the possible problem if ur amp goes thru the cycle and goes directly to protection when I turns it on with no speaker loads or rca connected. HD10000 taramp.
Repaired it before 🤦🏼♂️ yep it’s Brazilian always messes up spends more time in the shop then in the car. Think I will just pay a few hundred more and get a bullet proof over built Korean amp. I got a JL HD1200 in one car and DC audio 2k’s and 175.4 in my daily and they have been going for years never even shit off once or anything.
Hi I have two gzca 5k amplifiers at 1 ohm giving 5600 at 14 volts and at 2 ohms giving 2800 my subwoofers are gzhw15 spl dual 1 ohm but I actually tested them are dual 1.4 ohms so final resistance or 0.7 for every two subwoofers or 2.8 ohms these amplifiers are manufactured In Brazil is there a problem running them on 0.7 ohms and what should I do so that no damage happens to the amplifiers and if not who has a method to run the subs on 1 ohms thank you all
BAREVIDS where do you get all the parts??, I'm having a hard time to look for mosfets replacements.. I can't fix my amp taramps hd3k because I can't find them online? Any suggestions.?? Thanks
@@mohammadkhan8462 1 week.. hahahaha I just want to fix it so I can sell it for like 120 bucks.. I have orion h2 15.2 and that subwoofer is way too much for this amp..anyways taramps refund me at the end and my cousin like the taramps and we get another one... I have the skar EVL-15.2 in a 3.9 cu ft and it sounds great.. so keep that in mind hd amp is like around 1400-1200rms.. I crank it all the way up with the skar sub plus the epicenter and no issues it all...
Have you experienced or know failures of Rockford's punch 60ix amp, back in the day? I have had one amp that kept fried many times without aparrent reason :/ Sorry for my horrible engish.
BASSstarlet your English is great. except for where you said (kept fried) we usually say kept frying. or fried many times. you English seems as good or better than mine. except for a word in a couple sentences. what is your native language?
Dude save yourself a waste of money and just save a little longer and get a Korean 5k you can think me later. The reason these Brazilians do so much power is there designed to run everything to the max that’s why you can’t abuse them without blowing them. The Koreans are not the are built extra tough and run not nearly as hard as the Brazilians. Think of them like cars the Brazilian is a cheap turbo 4 cylinder that’s running right near the red line all the time so push it any more or abuse it in any way it will blow and the Korean is like a big block that makes the same power but does it at 1/4 the redline so obviously it can last way longer as it’s not even being pushed hard. That’s why you can wire them lower and they will do more power and survive where a taramps would go poof. And it’s not that all Korean amps are good and all Brazilian amps are bad it’s more how and who builds them. Take for instance sound digital they have some realizable amps that can do massive numbers but you will pay more for them. And take the CT sound team 7k those things where going out left and right a year or so ago when they came out. Just do your research and don’t try and get 5k Watts for a couple hundred bucks and you will do fine. Hell technology has came so far even some of these cheap amps are decent now even if they don’t make huge power they still hold up ok.
awesome vids mate! been following the channel for quite a while and this just came in handy as i blew my 5.1 Pioneer AV reciever and i'm trying to repair it myself. Offtopic on this; I have a Soundstream T4 12" sub that I need to build a box for and would like your input :) Here's the woofer specs; Fs 36.5Hz, Vas 1.034 cu.ft., Qms 3.584, Qes 0.414, Qts 0.371, Xmax 0.63in. It would go in a trunk of mazda 626 (4door) ran by Renegade REN 1800 - 2ch class AB amp, I've heard it can push about 800 Wrms to 2ohms stable. I'm open to any design idea and as of watching your independance rise vid I'm undecided as to the box design! Thanks mate!
Taramps 8000Hd after I replace all the output transistor amplifier come on but when turn up volume it keeps a loud humming noise and going to protection can anyone help on this problem thank you
I'd add a heavy-gauge pigtail to the annoying output transformer leads to make the gate driver IC easier to service in the future. With an overrated Brazilian amp, it'll need to be serviced again unless the owner backs off on the low impedance.
Thanks for the fascinating insite into boom,boom amp repair Just a suggestion! Why don't you buy some alcohol and clean the board I will save you time and money,just think you never see a car sprayer with a dirty spray gun It will get you more work and a excellent reputation
FlatFrog69 RR in time. it would be an extra cost for the customer and most just want it to work and don't care what it looks like inside! I always clean any conductive soot etc.
Ay mate! Pick up some SMD capacitors on ebay, for a few dollars you can have a mixed set of around 1200 pieces ranging from pF to uF. Think i paid 5 dollars for my set. It looks like a size 0603 to me but not sure
hey im just getting into the car audio world and i actually got a few amps from some friends. all of them has some problems and are in need of repairs and i was hope to learn how to repair them myself with your help if that is ok with you.
Can somebody please help me identify this mofet is for me taramps HD 8000 I had it repaired it has three others those read 650 where the 836 is on this one
Gain KNOBs can be replaced, usually they are just variable resistors. Take some measures on it while spinning the knob carefully, and look for torn connections. If there are any dead points, you should change it. Be sure that the amp is not powered while you're doing any work on it.
If you hape problem with gain its either potentiometer or preamplifier, if you dont know how to replace either of those i would suggest to get someone to look it up, fixing it without basic knowledge can lead to more damage but if you are willing to learn than give it a shot.
For the size and price of these Tarramps they seem like such a good deal, but I e seen these amps catch fire too many times. I just don’t trust them. I stick to the Korean amps. The Orion line seems to be pretty on top rite now
Ive never seen them catch fire. Ive heard of their mosfets blowing but never catching fire. But if you were to compare a brand by how often their fets blow, most brands would fit into that category

Hey bro just need a little advice I have the same model but one half of my output transistor blow in the output section replace it with driver IC. amp power on ok but when I turn up the volume there's a loud hum and amp go in protect have you ever experienced this problem.
I have a question about a Lanzar opti 2k, ic by the driver board was bad KIA 393p ic, I replaced it and still in protect?? Any suggestions on what else to check? Input and output FETS are all in spec, two resistors were bad on output driver card, buddy of mine had it in his car forever, power wire at battery corroded, and he thinks dead shorted and blew fuse. But amp still played for another month but kept getting louder fan and like a whine/screeching noise. Took amp out, I looked at it and now in protect mode. Thank you sir any help is greatly appreciated
Sounds like more issues in output drive circuit. Determine why it is in protect, as you power it up look for rail voltages in the wrong places on output mosfet pads and go from there.
I figured it out buddy, thank you sir for your help!! It was loose pins into actual drive card from board upto driver card pins were broken. Now gotta find parts
Do you clean the pcbs with Alcohol after repair
i have an amp im working on that looks far worse than yours, how do you go about cleaning a board like this? sink sprayer and then followup with isopropyl?
Hi I have a taramp 50kw the need to change the output mosfet bot the numbers are grind any idea please help
The TC35 had a double connection of solder creating a short. You can barely see it at 3:04. It create a nano resistance in diode 448A towards the IC which causes a surge in cap R598. It wont blow it out, but reverses the vacuum connectivity, if you will, and the solder reacts as a negative magnet of sorts making the thermistors and IC's give a drive wave of negative 5 plus 4 (obviously not adding up to 1). Next time, short the PC68 Cap and leg 2 and 6 of the 1I96 Stationary board and it will bypass the reaction board. You will get less Bass but the treble will be amazing. Also, This board was made in a factory in Nyflanigan during a drought where fish were abundant, but deceased. So, Fish oil caps from this region are highly suspect to fail. You will smell an odor if the caps pop. It may smell like your urine. Which means you need to drink more water.
epic troll is epic sir!
Lmao thanks for the help
@@barevids hey boss I appreciate your repair vids great stuff I was wondering where I can purchase the current sensing ic ir25750 looks like it’s obsolete or is there a replacement part I can use , I would appreciate it thanks
Nice brother them amps are scary would never want one
sleeper10s its pnly got 200v caps ha ha
That's nuts
What’s the possible problem if ur amp goes thru the cycle and goes directly to protection when I turns it on with no speaker loads or rca connected. HD10000 taramp.
Repaired it before 🤦🏼♂️ yep it’s Brazilian always messes up spends more time in the shop then in the car. Think I will just pay a few hundred more and get a bullet proof over built Korean amp. I got a JL HD1200 in one car and DC audio 2k’s and 175.4 in my daily and they have been going for years never even shit off once or anything.
thats because youre not loud

Where from the UK are you from? Been watching your videos for years since before the basso profundo rebass, hope your well bro.
Hi
I have two gzca 5k amplifiers at 1 ohm giving 5600 at 14 volts and at 2 ohms giving 2800 my subwoofers are gzhw15 spl dual 1 ohm but I actually tested them are dual 1.4 ohms so final resistance or 0.7 for every two subwoofers or 2.8 ohms these amplifiers are manufactured In Brazil is there a problem running them on 0.7 ohms and what should I do so that no damage happens to the amplifiers and if not who has a method to run the subs on 1 ohms thank you all
Help pls. i am looking for ic Pic16f1829i/ss with the 10k taramp program on it. this ic give the tc4427 it drives ( Square weaves ).
BAREVIDS where do you get all the parts??, I'm having a hard time to look for mosfets replacements.. I can't fix my amp taramps hd3k because I can't find them online? Any suggestions.?? Thanks
How long did it last
@@mohammadkhan8462 1 week.. hahahaha I just want to fix it so I can sell it for like 120 bucks.. I have orion h2 15.2 and that subwoofer is way too much for this amp..anyways taramps refund me at the end and my cousin like the taramps and we get another one... I have the skar EVL-15.2 in a 3.9 cu ft and it sounds great.. so keep that in mind hd amp is like around 1400-1200rms.. I crank it all the way up with the skar sub plus the epicenter and no issues it all...

@@lunam7249 thanks 👍.. hopefully I'm able to keep working on it.. thanks again
How can I get your info to repair one of my amplifiers
User error killed that 10k
Have you experienced or know failures of Rockford's punch 60ix amp, back in the day?
I have had one amp that kept fried many times without aparrent reason :/
Sorry for my horrible engish.
BASSstarlet your English is great. except for where you said (kept fried) we usually say kept frying. or fried many times. you English seems as good or better than mine. except for a word in a couple sentences. what is your native language?
Yeah it's "apparent"...my native is Greek.
Thanks for the reply.
You had to watch stray power strands falling into the back of these amps The rails were open on the corners
You got some skills
what is you opinion on taramps ? im thinking of buying the 5k
They pretty much suck ass, you get what you pay for.
Dude save yourself a waste of money and just save a little longer and get a Korean 5k you can think me later. The reason these Brazilians do so much power is there designed to run everything to the max that’s why you can’t abuse them without blowing them. The Koreans are not the are built extra tough and run not nearly as hard as the Brazilians. Think of them like cars the Brazilian is a cheap turbo 4 cylinder that’s running right near the red line all the time so push it any more or abuse it in any way it will blow and the Korean is like a big block that makes the same power but does it at 1/4 the redline so obviously it can last way longer as it’s not even being pushed hard. That’s why you can wire them lower and they will do more power and survive where a taramps would go poof. And it’s not that all Korean amps are good and all Brazilian amps are bad it’s more how and who builds them. Take for instance sound digital they have some realizable amps that can do massive numbers but you will pay more for them. And take the CT sound team 7k those things where going out left and right a year or so ago when they came out. Just do your research and don’t try and get 5k Watts for a couple hundred bucks and you will do fine. Hell technology has came so far even some of these cheap amps are decent now even if they don’t make huge power they still hold up ok.
awesome vids mate! been following the channel for quite a while and this just came in handy as i blew my 5.1 Pioneer AV reciever and i'm trying to repair it myself. Offtopic on this; I have a Soundstream T4 12" sub that I need to build a box for and would like your input :)
Here's the woofer specs;
Fs 36.5Hz, Vas 1.034 cu.ft., Qms 3.584, Qes 0.414, Qts 0.371, Xmax 0.63in.
It would go in a trunk of mazda 626 (4door) ran by Renegade REN 1800 - 2ch class AB amp, I've heard it can push about 800 Wrms to 2ohms stable. I'm open to any design idea and as of watching your independance rise vid I'm undecided as to the box design! Thanks mate!
Hi have Korean manufacturer started doing amplifier that deliver at least 4k at 12v 13v yet? Your videos are very inspiring keep up the good work.
Pretty sure there are many Korean boards doing 4k and much more. Check.out Crescendo amps, pretty sure they are Korean.
Nice videos man
Great

Hi, I just want to ask, why you don't user small tip on micro soldering iron? working with theese small fckers would be easier :-)
I do usually, it snapped! haha waiting one new tip.
how do you adjust the offset on this amp?
How do I send u a picture I want to show you a amplifier
Taramps 8000Hd after I replace all the output transistor amplifier come on but when turn up volume it keeps a loud humming noise and going to protection can anyone help on this problem thank you
I'd add a heavy-gauge pigtail to the annoying output transformer leads to make the gate driver IC easier to service in the future. With an overrated Brazilian amp, it'll need to be serviced again unless the owner backs off on the low impedance.
Thanks for the fascinating insite into boom,boom amp repair
Just a suggestion!
Why don't you buy some alcohol and clean the board
I will save you time and money,just think you never see a car sprayer with a dirty spray gun
It will get you more work and a excellent reputation
FlatFrog69 RR in time. it would be an extra cost for the customer and most just want it to work and don't care what it looks like inside! I always clean any conductive soot etc.
I agree with you but if I am doing jobs like this, I would like to maintain a good reputation and do it right. Don't you agree? Anyway great video.
Ay mate! Pick up some SMD capacitors on ebay, for a few dollars you can have a mixed set of around 1200 pieces ranging from pF to uF. Think i paid 5 dollars for my set. It looks like a size 0603 to me but not sure
You said Bander amp in this video can you get me link for the company ?
Jason Robinson it’s Banda
"banda"
I think that those SMD caps are 220nF also the ESR doesn't look too good, 4,5ohm it's very high
hey im just getting into the car audio world and i actually got a few amps from some friends. all of them has some problems and are in need of repairs and i was hope to learn how to repair them myself with your help if that is ok with you.
wow can u recommend any books on car amp repair....
I have forgotten your email address and i have a tarams with a problem! Where can i reach you ?
Saludo tienes el diagrama de ese amplificador
Can somebody please help me identify this mofet is for me taramps HD 8000 I had it repaired it has three others those read 650 where the 836 is on this one
You should be making your own amps
Do you fix amplifier If I send it to you, I'm in the US.
No I can't take work from overseas
OK, bro, thank you.
Hey no flux?
Thank you
Any tips on how to fix a gain nob?
Gain KNOBs can be replaced, usually they are just variable resistors. Take some measures on it while spinning the knob carefully, and look for torn connections. If there are any dead points, you should change it. Be sure that the amp is not powered while you're doing any work on it.
If you hape problem with gain its either potentiometer or preamplifier, if you dont know how to replace either of those i would suggest to get someone to look it up, fixing it without basic knowledge can lead to more damage but if you are willing to learn than give it a shot.
Goodday I got issue on my taramps hd10k
The issue was it's turning on but sounds like noisy and not clear
what really fixes it is your magic spit from blowing on soldered connections
146 volts AC from only a 9 volt DC power supply?? Has anyone ever attempted to run house appliances from their car amps before? o.O
yes...it works if the amp is big enough!! but it eats car batteries in about 6 minutes!!!
You've got good eyesight to read them ic's bro
For the size and price of these Tarramps they seem like such a good deal, but I e seen these amps catch fire too many times. I just don’t trust them. I stick to the Korean amps. The Orion line seems to be pretty on top rite now
Ive never seen them catch fire. Ive heard of their mosfets blowing but never catching fire. But if you were to compare a brand by how often their fets blow, most brands would fit into that category
Dada prise
vape on👍👍👍👍
I doubt a lot of people are truly clamping 10k tho but if I can get 7k or 8k out of this I’m fine
brilliant
When you going to write a book or e book on repair.
Steve B no need, Perry already wrote one which you can buy on the bcae1 website.
barevids BCAE1 havent seen that site in years. Might look at it again.
i can hear it.
Someone needs to buy you a case of brake cleaner, then you can clean these damn boards LOL
