Hello Ed!

The usual fix is to use a 10-watt, 70-volt line to voice

transformer. The 10-watt tap on a 70-volt line to voice

transformer will provide a decent match to a 500/600 ohm
output. In a
pinch, an ordinary filament transformer will do. Get a
transformer
with a 120-volt primary and 12.6-volt secondary and
connect the 120-
volt winding to the receiver and the 12.6-volt winding to
the speaker
and you are done! --Ed

thank you for the suggestion, I do have a spare 120V
primary transformer
lying around (I live in a 240V country, so no use for it).
I could also
wire my own transformer, but that would take some time.
I don't know what a line to voice coil transformer is, can
you explain
better this part? Thanks a lot.
Best regards

I've used filament transformers many times and they
work well. While the fidelity may not be as good as a
special purpose audio transformer I doubt you will be able
to tell the difference in this application.
The Hammarlund Super-Pro is a very fine receiver and
will repay your work in restoring it.
