If you look at the sch with one #67 being at the top (or at the right most) and another being inside (closer to the 80 tube) - if all was connected to the top cap it would hum as this is the "unfiltered" voltage; the filtered one (by the field coil) goes to the one close to the 80 tube and this is where all those RF power and #55 resistors should've gone to.

Anyway, all is well that ends well.

Good job!
