Dual STK4050V amplifier project
Hello, i am beginner to making amplifiers but i have father who knows electronics.
I might not write everything right but i hope you understand what i am about to make.
I need to build 2x200w amp using two STK4050V chips.

As i understand both chips need 66v , is that after caps?
Is it fine to use 45v dual output transformer 530va (i know 1,5*wrms is reccomeded)?
45vac*1,44 makes 64,8v , is that fine voltage (66v reccomanded)?
Is there point to fit 30 000uf or more caps for both channels?

I am sorry about my english, i am from estonia.
