Hi everybody,
I have a problem with my MS-2. It turns on but produces no sound. I took it apart but visually all components and connections seem fine. I haven't tested them, and I'm not sure what I should test. I see that there is a link to a guide, on this page, but the link doesn't work. Did anyone experience the same problem ?
Thank you for your help !

Links are explicitely leading to an error404 page. I mean the page isn't missing, the link is built to show up this 404 page, so I think the guide's never been written :(

The tone knob on my Ms-2 is stuck, I can't move it. What do I have to do?
Sander Lijster - Contestar
Gently prise off tone knob with small flat end screw driver. Working your way round till it pops off.
Remove 10mm lock nut with socket. Should only be finger tight so should come off easily. With the amp lying on its back squirt a very small amount of penetrating oil into the shaft / switch. Gently and carefully push the shaft / switch to the side so that oil can work it’s way around. Leave for a minute or two.
Now with a flat ended screw driver (about 7”long for leverage) carefully but firmly try to turn the switch. Should come free at this point.
Mine was stuck for over 10years and it freed up easily. Wipe away any excess oil and reassemble.

I have a Marshall MS2W portable amp and it was working fine up until today. I am running it on battery. All of a sudden it started cutting out, kind of like interference and the little red light flashes from bright to dull. Could it be the battery dying? I hope to heck it aint my Ibanez Gio GRX40. Please help.

Basically my amp is just not turning on. I’ve replaced the battery and I’ve installed it properly however it’s just not turning on no light or anything.

My ms-2c is not working with a 9v or a 12v ac/dc cable. They both are working properly but when I connect to my amp they just show light in the adapter but doesn't work. The 9v cable blinks or hiccups and there's a low volume sound from the amp when it hiccups. Please help (sorry for bad English not my first language).
