#14 Master Volume AB763 Fender Deluxe Reverb and others

Video describing the process of adding a master volume control to a Fender AB763 amplifier such as the Deluxe Reverb, Vibrolux, Twin Reverb etc. I explain how the AB763 circuit works from the phase invertor to the power tubes and how to implement a master volume. I then install a master volume and re-bias the amplifier afterwards.
