Years ago, when the Earth was young, around 1995. Someone tossed out a vintage Ludwig drum kit that had been BRUSH painted. I rescued it, painstakingly restores it to a beautiful natural finish and gave it as a birthday present to my best friend who was also my drummer at the time. Being a drummer...

It sat in my jam room for a couple of years, but one day my wife snuck it out of the house and took it to a guitar repair shop that fixed it for a hundred bucks and she gave it to me for Christmas.

[@oBsRVr666]

Two tips come to mind seeing you repair this: 1) If the faulty component (in this case the TDA chip amp) has already been cut off I find it much easier to just melt the solder on the remaining legs with the soldering iron and pull them out with a small pair of needle nose pliers. This way it's much easier to get the solder out once the legs are out and it's less likely to lift a pad with the desoldering pump. 2) If you don't already own one: An ESR meter is a good investment to check for bad electrolytics. Some electrolytics capacitors fail in such a way that the capacity on a normal DMM will still read fine but the internal impedance will act like a short circuit. You probably know this already. :) Nice repair. Glad you fixed it.

Excellent video! I had exactly the same amp, bought on ebay for not working/spares... (had been left at a theatre after a gig). Paid about £38, took it home..didn't work. Fiddled about a bit and found that the main volume pot was faulty and left in a position where nil output existed... Had to take the main chassis out and remove the faulty pot (which was integrated) by deslodering. Worked ok after that. Thing to remember with these amps is that they MUST be connected to speakers otherwise there is nowhere for the power output to go when switched on, result..smoke! I found that the effects on this amp good enough to eliminate the use of numerous pedals.

[@freesk8]

I found a little version of this in a dumpster about a year ago. Marshall MG 10 CD. It needed only two things: the input jack needed to be re-soldered, and the transformer inside had worked loose and needed to be bolted back down. But all the nuts and bolts were rattling around inside. So, that was probably worth about $30 that I got for free. :)

[@myjs_dot_iosupport994]

Some feedback: 1) check fuse, 2) check all the tops of the cylindrical capacitors looking for bulges, 3) smell the big transformer to detect a burnt varnish smell, 4) look for cold-solder joints, 5) check all high-powered connectors for evidence of arcing. When soldering or removing soldering-for Peet's sake-always use flux. When trying to remove solder like you did, smear flux over a braided metal sheath and apply heat to that and you bring it down to the pads (which also have flux). The braided metal will wick the molten solder off cleanly like you wouldn't believe, leaving the pads unharmed. Clean with alcohol and acid brush between desolder/solder events.

[@myjs_dot_iosupport994]

You need one of these: kzbin.info/www/bejne/fajSZKN7fZybi6c When you build your replacement board, it's important to gauge the wires so that they'll carry the same amount of power that the original board did. Look at the width of those +/- rails; I think you under-gauged those connecting wires (pretty sure).

[@kongandbasses8732]

Those Marshall MG are not heavy sought after, because they have "not enough tubes" for some korksniffing tube afficionados. To be honest, they have a place in heavy metal, not only because Chuck Schuldiner of Death played a MG series amp. Some guitar channels checked the MG's out and found them not bad at all, if a reasonable priced amp with lots of gain and a brilliant high end with some sizzle (and maybe some noise) is what you are looking for.

[@simonssparestrings8910]

sizzle is the word

[@TheGuitologist]

I didn't know Chuck used one of these. Cool.

[@JakeTerch]

Kong and Basses Chuck used the Valvestate, the MG’s predecessor.

[@resistorstudios]

MG is not what Chuck used nor is it a predecessor. Chuck used two Valvestates, the 8100 and the VS100, exclusively, and that amp series was replaced with the AVT (Advanced Valvestate Technology) after that. These amps are tube and solid state hybrids with a single tube in the preamp section and had a unique voicing. The MG is entirely different and was entirely solid state and marketed towards the entry level niche. The AVT was still around at the time and was intermediately priced at the time while the JCM were flagship models.

An MG15DFX for £100 was my first amp (2002?) which died in a week on headphones. Returned and upgraded to 30W for +£30 and still use it. The volume would suddenly decrease, even after I fixed a few solder joints. Recently I got some Servisol cleaner and cured it briefly. I got my Ibanez SA160QM back then, it always had a wonky tone pot and I broke the jack. I fixed it and finally did a setup last night. I just bought an Ibanez SR300E last week in metallic red too. It sounds pretty good clean and with all the EQ knobs I figure don't need a bass amp.

The bearings got a little screwed up from the rust, but it still works fine. Replace the bearings and it will be like a new fan. I also personally found a whole house fan on the side of the road from the 50s. Only thing it needed was a cleaning, oiling, and new power wire. Still runs fine. I could up and sell it right now for $300 easy, but I like it so I'm keeping it.

[@Whydoyoureadme]

Scott Dunn No, they dont. No need to lie to others or yourself. If you personally prefer a MG that is fine, but what you said is not true. Have you tried playing a MG, a 2203, and a boutique EL34 next to each other?

[@scottdunn2178]

@@Whydoyoureadme Chill. It was just a general statement. I play an early JCM 2000 DSL100. And what's a "boutique EL34"? Just because an amplifier is equipped with EL34's doesn't automatically mean it's a killer sounding amp.

[@Motocicleiros]

That's incredible! Being totally honest I wouldn't bother to try to bring it to life as soon I saw that "digital FX' section. I immediately thought 'oh, sure, one of those craps' and I really doubt that he would make it work again. I am amazed.

[@iakirov]

I've never heard before of boards becoming conductive. One more thing to keep in mind, thank you. Stay safe!

[@paultheroman6637]

Good sir, your tenacity, diligence, and resourcefulness are an inspiration to anyone who has the ability to see every disappointment as an opportunity. I appreciate your willingness to do battle against this throwaway consumer paradigm in which our first impulse is to discard broken things instead of trying to evaluate their value either for repair or salvage. We live in the richest country on the planet and I see valuable things discarded everywhere I go. If things ever do go south and society is reduced to something that resembles a "Mad Max" movie, It will be folks like yourself that will be highly sought for your ability to diagnose, analyze and correct/repair the technology that will be essential since no more replacements will be coming. Best wishes and prayers for your continued health, success, and prosperity.

I repaired one of those MG Marshalls many years ago. As I recall it was also a failure of the amplifier chip TDA7293. Same overheated device but mine was due to a failure of the cooling fan. These chips run hot evn at idle with an average quiescent current of 75mA (~6Watts to dissipate) so a failed fan will kill the IC even though it is supposed to be thermally protected. I repaired mine by replacing/upgrading the fan and beefing up the heat sink by using copper and almost tripling the surface area. Okay now I must criticize your use of Chinese clone semiconductors. They are NEVER to the specifications of the original manufacturers. Do yourself a favor, spend the few extra bucks and buy legitimate parts from reputable distributors (DigiKey, Mouser, etc) and genuine manufacturers (ST Micro, etc.). Awesome playing!

[@Mark-iq6hi]

JJ, Brad does what he wants because everyone is a expert at electronics on here. Let Brad do what he wants to do and don't criticize!

[@odinfolk]

And do yourself another favor and never buy a Marshall amp...they are absolutely pieces of garbage.

[@Imwright720]

We live in a society that when something breaks we just trash it. I have a dust buster, 2 actually, that the switches quit working. I just added in my own. Silly to throw away something that can be fixed. People can diagnose anymore, they are just parts changers. You followed the smoke and used your noggin and figured it out.

[@GuitarMooseMusic]

Man if I could get lucky enough to find a Marshall in my dumpster that I could get to work like that...I’d be more than happy to self quarantine myself!!

[@gerrykavanagh]

Nice job. Good diagnostic process. This is rapidly becoming one of my favourite channels.

[@johnas2004]

Nice repair, great to see you persist and trace the fault to the PCB, got to keep stuff out of landfill. Stay safe.

[@SuperJiggawhat]

The FDD on Marshall amp's stand's for "Frequency Dependent Damping." It basically add's depth and make's it sound more like a tube amp.

[@mrtwistyneck]

SuperJiggawhat my first thought was Freakin' Digital Delayyyyyyyy!!!!!! i'll see myself out

[@SuperJiggawhat]

@@mrtwistyneck I had to look it up on Google lol

[@AlexH8280]

As soon as I saw "MG" I knew immediately that was why they tossed it in the dumpster. (kidding)

[@footnotedrummer]

Yeah... you can get these used for $130. It was cool watching him get to the bottom of the issue, but it wasn't really worth his time and effort. However... there is value in the satisfaction that you fixed something.

[@ironblast5]

Cheap as they are I think they sound pretty solid especially for a startup rig

[@DreadNovella]

@@ironblast5 I agree. A half stack will keep up with anything else.

[@shavedwolf87]

I bought one of these nearly 15 years ago, within a matter of months I was onto my 3rd head due to fan issues. Years later it still runs like a champ, must have been a bad batch of these.

[@Virdae]

It is actually a pretty good amp if you just use it right. Crunch channel with the gain almost as low as possible with the volume as loud as you can bare.

[@mrsenorsalami]

I found a 1972 Fender Rhodes stage piano in its case at a council clean up, in perfect condition. And a Shenei Fuzz Wah. Crazy people

[@almostliterally593]

WTF i would orgasm and shit my pants at the same time

[@davecooper360]

I'm actually a huge fan of this particular model, the MG100hdfx. I like the reverb a lot. Also I like the effects loop mix adjust!! Comes in handy for troubleshooting .. take out the effects loop without unplugging anything. I mostly use the clean channel in crunch mode... boost with a Tubescreamer. Plug into a quality cab with good speakers and it sounds great.

[@2011littlejohn1]

Impressive demonstration of patience; as a guitar player my equipment knowledge is I plug the guitar into the thing called input and press the switch marked on.

[@johnnybrown9581]

Sue This? I’ve never heard of that guitar brand. Looks cool!

[@TheGuitologist]

It's Authentic.

[@3dlabs99]

Haha yeah ... reminds me of something.. cant quite place it... probably some kind of Fender guitar ;)

[@SuperJiggawhat]

@@3dlabs99 You're right, it definitely looks like a Kiesel...🤪

10/10 for perseverance and bringing that Amp back to life....you play good as well Mr G...peace.

[@elmanoazul]

“SUE THIS!!!” Brad your killin me!! Great stuff keep up the good work!!

[@Cmoth040]

I know what you mean about broken Marshall logos. I replaced the grill fabric on my old Lead 12 Marshall that I've had since 88' a few months ago. Prying off the logo gave me such anxiety I looked up videos on doing it properly. Thankfully, got it off in one piece with the posts intact and was able to remount it into the new fabric. Looks like a new amp. Those logos are expensive to replace.

[@matthewb8229]

Some basic electronics knowledge sure does go a long way! I bought a late 70's Yamaha B100II bass head, replaced a couple pots, and that thing has served me very well. Lots of gigs, jams, etc.

[@TheUffeess]

Sweden has been hit so hard by Corona that even the hockey has been stopped. But then you are back and it feels like there is hope for better times. Thanks!

[@Sparky6string]

Damn you're good. Also you deserve these things with as excited as you get. Here's hoping one day you find a nice old JTM 45 in the dumpster with a resistor out.

[@REDDRAGON666ful]

I’ve had this same amp for 10+ years now! Never a problem, the distortion just wasn’t enough for me lately, moved up to a Metal Zone and a MXR Fullbore Metal!!!

[@REDDRAGON666ful]

ihate names the Fullbore Metal seems to be doing a great job, my Metal Zone is still a favorite, I only use for certain songs and solos now though...!

[@michaeldeas1969]

I had a welder on my truck Yesterday and I was only about sixty miles south of you. I could have stopped by and sparked that stand back together for you.

[@TheMadninjamike]

I got one of those just sitting in a closet up the hall that was tossed out the same as yours....(I run a rehearsal warehouse, and hammerhead musicians throw stuff out all the time). You've just help move the dang thing up the list of my gear repair triage. this quarantine crisis is the perfect time to whittle away at repairing all the gear that has piled up for the last few years. What do you wanna bet its gonna need the same chip replaced after tossing the conductive PCB and rolling a DIY replacement board of my own? Thanks for taking the time and energy to do the entire repair on an amp most techs would probably throw out. NICE workbench chops too you just got my subscribe buddy
