Tube amp question

I am a novice tube amp owner. I have had my Black Ice Audio Fusion F22 for not quite a year. I want to understand plate voltage and how it impacts tubes or vice versa. I want to roll the tubes to the KT150's which Black Ice has said can be used without issue. The plate voltage of the amp is 500v. In other posts, someone said that KT150's require a minimum of 600v at the plate. Since Black Ice says their amp can use them, does this rating depend on the circuit? I have some basic understanding of electronic circuits and I googled plate voltage but I'm still not clear on what it is exactly. Can someone knowledgeable with tube amps help me understand this? Thanks!

Plate voltages some mfg companies run nearer to max on the plate for they may sound a bit better ,but at the expense of tube longevity.

i have owned black ice f35 and has very good size transformers ,

ican see the F35 have big enough power supplies  but the F22  is pushing it 

for sure it will tax the power supplies much more  kt88, or maybe even  KT 120..

Did you speak with tech support at Black ice about using KT 150 s

Jarred too should know  thsts a Bigstep up from stock EL34 s
