Mark V decided to just....die

[Mark V]

So, I was pulling some mean leads during band rehearsal, when all of a sudden I had no sound comming out the Mark V... I looked at the amp just in time to see that all the lights got turned off....
Then a HUGHE amount of white smoke emerged from the back of the amp (head version), and the whole place smelled of burnt electronics...

I have no clue what happened... The fuse blew that's for sure, but seems that whatever caused it, took out some other parts (transformer maybe?).
Luckily the amp is still two weeks in warranty, so I dropped it off at the shop and they were going to send it to the importer (not sure if they'll send it to Mesa).

Anyway, the Mark V is a cool amp and all, but it seems to have some serious issues though... Before I had the head version, I owned the Combo version, and that one would blew fuses every so often...and I could never really find a reason why (nor did the shop where I bought it).

Guess I'll be selling this one when it's fixed.

Sounds like you experienced a shorting power tube, which took out a screen resistor as current overran the tube. Its not uncommon in a severe short, and is due to power tube failure. Have the resistor replaced, along with a new fuse and power tube - and you'll be good to go. Thanks!
