Does anyone know the bias on a VTL 225 with KT90 tubes in them?

Hello, I would like to know what the bias should be on a VTL 225 monoblock amp with KT90 tubes in them. Thank you

I don't believe the values would vary between KT88's or KT90's, and they tell you how to do it if this is your first time out. Good luck.
