Sam, here is a picture of what I made for the power supply. It is from a common issue schematic. The power transformer has a split primary, two 125 V inputs and you use one for producing the 90V. As I recall (hard for me) there are two 6V secondary windings, only one used to provide a regulated 1.5V for the filaments. I hope this helps.
Jerry PS: sorry for the cruddy picture quality.
