unkown output impedance measurement?

I was wrong it's only 10 watts. I know of no reason, perhaps someone
here will tell us. They made tens of thousands of these so it must have
had a need...

I can't see rhyme or reason for such a high power output at that
impedance.

No cathode follower.
Any headphones work fine at 10 ohms.

If 10 ohm headphones work fine I doubt the output is 600 ohms.

Usual reason would be to drive several small speakers or to do so over a
long run - like 100v line. Where a matching transformer is situated with
the speaker.
