Realistic SX-190 Ham Radios - $150 (Syracuse)

Time to clean out the house.
Starting with two Realistic SX-190 11-band Short Wave Receivers - non-working.
Physically they are in great shape but I can't get sound out of either one.
Is it me? Do I have it set up wrong? Don't know, don't care.
Only one speaker.
I have a manual, though.
Take them both for $ 150.
