Fender pro blowing fuses

Just back from a Bank hol outdoor gig, half hour on half hour off all afternoon.
My Pro Reverb blew three fusses during the course of the gig, I put some power tubes in after one set and a few numbers later it blew, changed preamp tube after another set then same thing, it did get through one set and a couple of numbers in the next before I gave up with it.
I have a solid state plug in instead of the 5u4 rectifier and didn't have the tube with me although I have one here.
The amp had a total rebuild six years ago using a Hoffman board and all new filter caps.
Could use some help on what to look for to find the prob.
Thanks in advance
Stax
