Another PL owner here. integrated evo400.
I just wanted a tube amp that worked without me needing to use a screwdriver and multimeter (though i have both).
I've experienced the "bad tube indicator" on the PL and been able to change that tube without anything blowing up.
PL apparently run the tubes very lightly and you should experience years of service from them.
the triode/ultralinear button on the remote makes this option a breeze.
Be careful of your back if you need to carry it anywhere. I don't think a thief could get very far with mine in hand.
