I believe that the board is ready to drop in, that’s when I solder in the choke and the power supply for the bias.
It may be fine on this simple amp, but just because it was ok in the 40's doesn't mean it can't be improved on. I built a Fender Princeton clone to the original circuit diagram and it was fine, with negligible noise/hum. However I have also build a Trinity amp with the transformers at opposite ends of the chassis which is absolutely silent.The power and output transformers are on a different plane.
I'm not sure how much impact the choke has on the output transformer (or the PT on the choke).
Like the power input section, this basic design has been in use since the 40s.
