Cleggy, that's absolutely correct. Pin1 to Pin1 etc.
I tend to use an octal base for adapters, as it is more robust (and stable) than the B9A.
But any of the existing bases (taken from a dud valve perhaps) would be fine.
If the adapter has longish wires and the valve under test might be oscillating, just slip some tiny ferrite beads over the wires in the adapter to stop any problems.
