spudspot,
you may want to think about sending the 66 preamp back to mark at rogue and having the magnum upgrade done at the same time. i personaly run a 99magnum and couldn't be happier, but i've heard that the 66 magged out is not a subtle difference. mark is such a competent owner and all-around nice guy, i wouldn't send my rogue gear to anyone else.
not sure how much of the magnum upgrade would cover your particular damage, but the mag upgrade is about $250.
definitely echo off to others in this thread that have had it done and see what you can expect. this will likely be $$$ well spent.
just my 2 cents
sorry to hear you got burned
but don't give up on the rogue
cheers
