I am sure it is good to have it up and making good sound. The 6C10 has cathode bypass caps on sections B and C. Section A is the cathodyne phase inverter and in stock form does not have a bypass caps. It is good practice imho for a tech to be specific as to what was done. I use a formal work order detailing parts and work. That becomes a repair/service history for the owner and any future repair person.
Enjoy.
