I am building a 5f1 and have an output transformer from a 65 Princeton Reverb ReIssue that I would like to use. Is this possible? There are 3 wires on the primary side a red, brown and blue. I figure the red goes to the rectifier pin 8, and the blue goes to the 6v6 pin 3. What is the brown for? I have attached a schematic of the Princeton if that will help. Or here is a link to the PRRI schematic.
