Fuse blows immediately but the speaker works from battery

crwdns2934249:0crwdne2934249:0:

Hello! I have a problem similar to a couple of other topics where fuse blows immediately. However, my speaker works fine from battery if it's recharged externally. Also, there is nothing is obviously burned or damaged on the board. Any suggestions how to diagnose the problem? Thank you!

Thank you, @jayeff ! I’ve found schematic of Marshall Stanmore on this link and attach the images

would you be able to suggest which element of the scheme may cause short cicuit please? I’m no expert in electronics but would assume that if something is burned/broken it should stop the flow of electric current rather than accelerate it?
