So the headphone jack on lower part of set should be high impedance. Of course to match output tube, BUT ALSO audio output transformer primary s not cut out when headphones connected.
A good set with at least 3000 ohms doesn't seem to effect speaker volume. Headset has really good volume.

This may be useful hard of hearing as I had to turn volume quite a bit since loud on phones. An extended cord for phones just thinking of it now will allow distance listening on chair if not another room.

A great added feature not seen on many sets.
