Decent choices, even if they are not Vintage WE tube types. I particularly like the choice of 6L6, but the WE near equivalent- 350B- would be even better.
Update on Production of Western Electric Tubes
In this month's issue of Stereophile , Julie Mullins stated in her Re-Tales column that Western Electric is working on tooling for specific parts , but intends on adding 12AX7, 12AT7, 12AU7, 6550 and 6L6 tubes to its lineup. Specific pricing was not mentioned, but she does quote WE President & Owner Charlie Whitener as stating that WE will not be able to meet Russian and Chinese tube prices due to the labor cost differential; and that it will likely be 9 months to a year before they are able to deliver quantity of tubes.
A degree of good news in my humble opinion
