so yesterday i was jamming at a mates place, he has a 5150 mkII and i had my JSX. i was worried that at half power i wouldn't be heard over him so i turned the switch onto full power before switching the amp on while still in standby. i left it to warm up the tubes for about a minute before turning it off standby onto play.suddenly boom, power goes dead, and i have blown a fuse.

long story short, apparently turning the amp from half power to full gives such a surge to warm up the tubes more than half power can blow the fuse. my question is, besides prayer, what is the best way to switch from half power to full power without blowing a fuse?

Turn it to full power.
Turn the amp on and put it on standby.
Wait 30 seconds.
Play.

Or so I'd do it...

The fuse is there as a warning sign to prevent further damage when something is wrong.
In this case, I would bet that one or two of the power tubes that are not in use when at half power are failing or have failed.

+1 Van, although it could be a fluke thing, sometimes fuses blow with no apparent reason. I would replace the fuse, if it blows again you know for sure somthing is wrong.
