Date Codes 6113 and 6313 places the production to January - March of 1961 and 1963.

Similar to a 6AS6.
Tubes are closely matched for Gm testing (see below) and internal structure - they are identical.
Black plates with top square getters.

They both test on the lower side but are still above minimum and have plenty of life left in them.

Gm Test = 2000 and 2000 micromhos
Minimum pass/good = 1540
