Hello all,

I've been given an old Hammarlund SPR-210. It needs a good amount of
restoration but appears complete inside and outside. I've seen on the
manual that it has 600 ohm speaker output and I was wondering where to
find such a spekear with this impedance. Probably there's need for an
external audio transformer to use any low impedance (I have many
in the 16-4 ohm range) speaker?
Any hint is welcome.
Best regards
