Default How much v/a on 300b's?


I recently got some mesh tubes, great sound! and the guy I bought them from said they are good to 37w dissapation, to my calculations on my voltages I can run that would mean for 380v which it is on now around 97ma, but my transformer also has the ability to up to 430v, which would mean that my current 74ma it's biased at should still work...

I'm curious if anyone has an opinion if I should stick to the 380v/74ma or up the voltage or up the current? And why?
