Keep making these videos! Very very helpful!

I’d love to know where to order parts for jl hd amplifiers,I have 1200/1and 900/5,both are very expensive to send off,your videos have helped me revive several but these two are not like most amps

It would be great to see you interview the JL Audio amp designer!

I picked a used JL Audio 500/1v2 today for $150 used. I haven't hooked it up to power yet but videos like this makes me feel good about having faith it works fine. Besides, I'd rebuild it if not. 😏👍

Very informative vids sir! Wondering if you’ve repaired any of the 1995-1996 ESX quantum amps?

superb vid sam! i lol'd properly with the hamster noise from the 14001! xx

Would you happen too have vacuum tube amplifiers laying around that could use repairs?

Great video!

What is a good source for service manuals/schematics for car audio amps?

When you say mastic... What exactly is that and what type?

Alongside these excellent amplifier repair videos, would you be able to do a couple of full recone/rebuild ones when you get the time? So far the only one I've really enjoyed is ShowtimeSPL's. I'd love to see your take on it and your tips and tricks! Thanks

im all for seeing barevids recone vids , i have some you could check out also

I got a 4 channel amp but the first channel does not operate properly, theres sound but allot of destortion and not full power, any advise

good day..I'm having a problem with my car audio..when I raise the sub volume on my pre amp my compression drivers are play bass when I disconnect my sub they play great ... system was hooked up about 2 months an am now getting this problem..bass amp is on an eqt audio control an the mids are on a cross over..any ideas what can cause it

how did you find out about the shorting of pins for hte JL amp? did someone give that info or did you work through the layout? if you figured it out on your own, could you make a video of how you reverse engineered the layout?

I love new repair videos from the channel, in fact I subscribed just for those videos but it would be easier to watch if you do more videos with one short repair in each one instead of multiple repairs per video.

how do you know what the 'banks' are? how can you look or measure at the pins to know which fets are in which groups?

Great vid

where did you buy the long probe ground cable? i think i have the same probe, tektronix right?

“Mastic”? What do you use for holding down components to keep them safe from vibration damage?

So if I have an inductor that's connected to the board but it looks like it's toast it needs to be replaced(inductor) mtx1500

Running a 300/2 and a 500/1 version 2. As far as sound quality, these are amazing. I'd say that jl audio brings you right to the line of point of diminishing returns on money vs SQ. Very few amps are better, dollar for dollar, watt for watt.

Who Zaskin I also have a 500/1v2 but a 300/4 and I agree with everything you said in your comment. Also, they’re built like tanks and as long as you treat them right they’ll in return treat you right for YEARS.

Can you repair a jbl a6000gti? I have one that only does static.

Can you recommend me a video I can purchase to learn to repair amplifiers? Please

Thanks for the tips

Could you make a video on the math you did in calculating power.

Smart kid . Where do you find all the schematics for all these amps .

So, I guess the JL amplifier has a rather firmly regulated rail voltage supply? That's pretty unusual. Personally, I've never seen that before either. Rail voltage supplies in most amp.s tend to have a pretty noticeable voltage fluctuation from idle to full load. Perhaps not with this particular JL? Did you happen to measure it to see?

Have you ever worked on Linear Power amplifiers? The SQ guys say they are extremely good sq amps, hand made and they use some very different parts inside.

Cory Gilbert there's nothing special about Linear Power topology. They are built for the most part, bullet proof. Sourcing T03 transistors is the only hard part. Unless your working on a 8001

I have a jbl like that it fried the caps! But I plan on replacing them, no transistors are fried, it would only cut on and off from someone else hooking it up wrong!

How to repair jl audio 500/1 amp. I got scammed... lol learning curve through offerup always test. Anyways I smell fried electronics. Are the mosfets on the side of the amp near the power copper coils. I would like to refurbish this amp! Help please

Good day how can I get in contact with you for some advice please ...

I have a 250 and 250v2 they are beast asf

Do you get away with using the 3205 mosfets on most amps instead of going back to the exact fet #. Does it seem like a more universal fet. Hopefully you know i dont mean "all" amplifiers, and the kind of situations im talking about.

@barevids

6 жыл бұрын

yes most of the time, 3205 are a very versatile and high current fet and work in almost all amps using to-220 case PS fets, its a good idea to change the gate resistors to 47r with them though. I have recently started using 3077 fets in some of the bigger more expensive stuff as well which are even higher power and seem to be seriously durable, but quite a bit more pricey. So far all the amps ive seen using 3077s have NEVER had them blow, even when the output section bricks itself badly. Its usually a 4277 IC driving them, i'm currently trialing a few amps to see how well the db139/140 drives them.

barevids thank you for the 3077 tip. I'll try those as well. I also have been using 3205's on almost all kicker, mtx, audiopipe,..... so on an so on style amplifiers. But im definitely going to give the 3077's a try. Thank you for the videos, keep up the great work!

Did you send your amp in and get it repaired

i have that exact same jl amp! i bought it in rough shape. the previous owner mix matched subs and ended up frying the 12 volt inputs =/ it melted. well. i ended up getting that all cleaned up. but now when the bass hits the amp draws like triple the amount of power that i would expect! have a decent size alt (130 or so amp) and it still drops me to like 10 volts. o.o wondering if you happen to know why? id like to find someone to fix it but most just tell me that jl is hard to work wiith cuz they wont give you a schematic to use.

First! Nice job too!

can i send you mine to fix?

Do you ever recap these amps?

@BenjaminEsposti

I'm wondering that too. I see lots of cheap brand capacitors in some amps.

@jlugk789

6 жыл бұрын

I've T whenever I repair a amplifier that is blown I'll always replace the capacitors especially on older amplifiers. I collect all the 1998/99 Mtx Blue Thunder and Thunder with the gold label amplifiers and even if the amp was working okay I'll replace the caps anyways to be safe. Since a lot of times if you check the Esr or capacitance you will find it's out of spec even if the capacitor looks like it's okay.

I have an amplifier that goes into protect mode as soon as the RCAs are plugged in deep enough for the ground shield to make contact. Anyone have any suggestions on what it could be? The crazy thing is that even though the amp is in protect mode, it is still producing a sound output...

@barevids

You have DC on the rca line. That needs to be resolved immediately. Will be something to do with line level converter, head unit, etc

Thanks for the Reply man!!! I'm a big fan of yours...So I thought it was the line-out converter I was using, so I installed an aftermarket deck and it still went into protect with RCAs connected. So I plugged in a different amp and it works just fine! So I'm thinking there's a break between the RCA shield and the circuitry...or perhaps a short? Am I on the right track? This is just a Volfenhag ZX-8400, but I am determined to get it up and running since it seems like it should be an easy fix.

@@MiKa-fu2wi damn that's weird, yes possibly something like that... I imagine it's going into protect cus it's detecting DC on the spk outputs. If you plug the rcas in first and then turn it on, does it still protect? Or only when it's already on and you plug them in?

Hi! I want to ask for an advice. I bought a used jbl gto755.6 amplifier. It seems that everything works, havent tested it under heavy load though.However when I opened to check if everything is ok, I have found 2 resistors that have chipped coat and light discoloration. Should I change them before using the amp? Pictures: imgur.com/a/Y2w67Ng Thanks for your videos and for any advice!

Likely just pull down resistors, check their value with a meter and as long as they're within tolerance it's fine
