Satisfying repair Stuart. At work we had a young engineer with keen eyesight and a steady hand. We relied on him to do all the removal and replacement of surface mount components. Some specialised equipment also required.

A short, yet satisfying repair. I appreciate your efforts to keep another modern amp-type object from the tip. It is in essence a disposable douche of an amp, however saving it is always preferable. Well done, Stuart. Cheers!

I have an MG 100 and and MG 30, great amps. They don't get a lot of love because they aren't valve amps, but I've found them to be quite capable and it is possible to get a good tone out of them if you work the EQ a bit, but where they really shine is how well they take pedals. I've replaced several of those audio chips and I don't know what the original issues are, maybe Marshall uses cheap components, but when I replace them I also use a mica washer and I've never had one go bad again.

I'm amazed we didnt hear your opinion of what a 'terrible design' the amp was 😂 It seems to be a standard part of your presentation! Glad you saved it. All of the boards are available from Marshall and they're not expensive at all. Bugger repairing all that surface mount nonsence, its quicker and cheaper to replace the front and DFX boards. The TDA2050 is a common failure on many amps, in fact i seem to remember you cutting one out of a bass amp because it only ran the tweeter some time ago 😊
Yes excelent value but of course you pay for it in lack of repairability.

@@stuartukguitarampguy5830 I bought my MG30DFX 9 years ago for £30 and it has never missed a beat. That's less than £4 per year of playing it, so I guess I can live with the lack of repairability at that price!

Hi Stuart, Thank you for this Video. I always struggle with solder wicks. First I thought that it was due to the lousy quality of the wicks, Now I think that my clumsiness is the cause ... Are you using a specific type or brand?
@adalbertus777

It helps to soak your solder wick in flux (can be rosin) and add some more of it onto the pins of the component being removed. If it's really stubborn, try adding some fresh solder on the pins.

Yes good tip from Adal below but you must also use a flux impregnated wick like Chemwick. Don't just use naked solder braid. Hopeless!

Hi Stuart, I have one of these and it has a peculiar problem. When you switch it on you can turn all the dials up and only at the very highest volume can you hear the softest sound from the signal coming from the guitar. If i then drop the amp from less than an inch from the ground or just gently rock it back and then bring it down onto the floor it'll kick in and work perfectly, everytime.(I discovered the 1st time accidently) Do you have any ideas what the issue could be?

Hi Brian That's an odd one. Best guess is loose connection or dry joint.

Surface mount components don't belong in a guitar amp of 30 watts & over in my opinion.. It' makes things very difficult unless you have all the right equipment, steady hands and 20/20 vision .. Well done for finding an old fashion component that was blown and just about replicable despite your shaking hand 😅.. We can all sleep peacefully knowing you've met your 'net zero' repair targets 🤣..

Truely awful amps, the components are the cheapest possible & run extremely close to their rated values, cheapest, flimsyest pots I've ever encountered, and a sound I can't live with. I'm sure the accountants are proud of their achievement.
