hello everyone..so glad i found this forum..very informative..i have a marshall 50 watt ss..the 5210..it has been an awesome amp thru the years..i recently got the new haze 40 which i like..but for recording the 5210 is king..about a year ago the amp volume(sound i should say) kept cutting out..i thought it was the speaker not being connected good..but i tried 2 other speakers and they would not work either..finally there is not a any sound at all..my repairman had it at his shop for a year and didnt even touch it which made me angry..so i picked it up and brought it home..i think he may have replaced the input jack but it still doesnt work...i am able to plug into the effects loop and get a faint sound out of speaker but that is all..it powers up and looks clean inside..but no sound when i plug into input jack..it also had some rumbling that sounded like a storm..which seems to common with this model..but i can live with that..sorry post so long..anybody with any ideas would be great..this amp is the last really good marshall ss..it was made in england..i have a mg50fx and it doesnt even come close..thanks guys
