Oldie but newbie

[Builder1950]

I'm looking at using a turret board. I'm trying to get in touch with Boot Hill Amps to purchase a 5e3 kit but am struggling. I'm also looking at the Hoffman, Ceratone and Mojotone sites but am seeing different values of components such as resistors in the different locations and am also looking at the original Fender schematics but I don't have the knowledge and am having trouble sorting it out. I'm sure some of the kit folks have made changes but I don't fully understand why. I'll get it eventually and am open to any suggestions (other that not moving forward).
