Confused--for a change.

Please recheck the tube types. A 6CD6 is an octal tube with a plate cap.
Is 60D6 correct?
Unused pins are frequently omitted. Sounds as tho you have two 6CD6 tubes from
different manufacturers. Count the pins and the holes. It's an octal if it 
has the keyed locating studd and the pins + holes = eight.
