First two will work fine. The third one does not say (or I did not see it) what impedances there are.
The 1st one seems to be what you want.
It says "55 mADC" which I think is the primary current rated. The tube you use uses 40mA so you should be OK.
From what John propose,, the second one is OK, a 45mA one.
The first one is 25mA one, it is underrated.

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
