I had grief with mine in my old combo. It was one of the issues with its lemontasticness.
It was linked to power outage problems, if memory serves...been a while.
My head that I got since has been 100% good as gold though.
I've had a number of amps run on tube rectification. Never had to change the rectifier on one. The longest I kept an amp was 10 years or so, with regular use

No sooner had I posted this than a 5AR4 failed in my Matchless Indy. Playing normally, then the sound faded away to zero in about 3 seconds. Didn't blow the fuse though
Took me a while to work out what was going on as I had not experienced this before. Took the back panel off the amp so I could watch the valves when it failed again, and saw the rectifier slowly turned it's lights off after about 5 minutes of use
The rectifier tube in my MV went out after about 3-4 months. It was still under warranty, of course, so they sent me a new one right away. It took the fuse with it when it went, too.
Funny thing, my band mate has a Vox AC30, and the rectifier went out on his amp shortly after mine. I got to thinking there could be something irregular in the mains--eating rectifiers.
