4.4 Installing the Bridge Rectifiers
A Bridge Rectifier accepts an AC voltage and generates a DC voltage which, in this amplifier, is used
as the filament voltage. You'll see a notch on the Bridge Rectifiers (part number: KBU6J): match the
notch with the '+' (POSITIVE) stencil on the board.
Install the 2 KBU6J Bridge Rectifiers at B1 and B2.
