Fred, one suggestion. Try to make the wires to the grid caps of the tubes as short as possible when you replace them. If the leads are left too long, you will get stray capacitive coupling between stages. This can result in oscillations, instability, alignment problems or hum pickup.

Aside from that minor point, a very nice restoration, especially considering the original condition.
