Hi all,
I have Vox AC30 jimi era Combo come to me with all of its 100R 1W grid resistors and associated 1W 1k5 resistors totally fried.
Obviously these will all need replacing and I will most likely uprate at the same time but would be the likely cause of the damage?

Do you mean the 1K5's at the grids of the power tubes (Pin2) ?
That would be strange for them to all burn, I would wonder if someone even tried the wrong tubes in there.
The 100R screen resistors usually burn from bad power tubes.

Yes all 1k5 and 100R grid resistors charred and destroyed.
I've seen 100Rs before but not both.
