To obtain a conjugate match it is first necessary to know what the source

If no reflections are allowed to reach the source, the source
impedance doesn't matter (except maybe for efficiency).

It is not given in a transmitting tube manufacturer's data sheets. Perhaps
it doesn't matter what it is - not needed?

Install a matching network that achieves a quasi-conjugate
match between the network and the load. That's what I do. :-)
