Blown fuse/ Rectifier - advice?

[espskully]

Hey guys. My Rectoverb head pooped out (just went quiet). I pulled the fuse and it has a brown ring around it (blown, yes?). I read that this could be a power tube gone bad. Is that neccessarily true, or could it just be the fuse? How do I tell if a power tube is blown?

Thanks for any advice,

-Aaron.

Just put in a new fuse first and then get back to us. Were there any other symptoms leading up to this or did it just "blow"?

No other symptoms - just blew.

YEAH ...well my amp has like 12 tubes in it ...im sure it was one of them ..not sure what it does ..but it had a cracked plastic housiong from me trying to insert it the wrong way ..i got it to ..lol...and once i turned it the right way it still worked...i have since replaced it ...but yeah ..no harm in checking ..might be a quick fix

I replaced the fuse and it blew again immediately. I checked the tubes and they are all secure.

Any suggestions?

send it to Mesa!

I wouldn't see it for years!

Anyway - I will try replacing the power tubes.

I pulled the power tubes and one of the sockets where the tube goes in has a pretty bad scorch/ burn mark on it. It may be worse than I thought!
