Hi,
 
I'm trying to help a friend with her set up. Old turntable/amp/speakers.
 
There is no sound from the speakers connected to the amp at all. 
 
Speakers are old Technics, Impedance 8 Ohm. Amplifier is an old Realistic one. Pictures attached.
 
 
She had the RCA to speaker wire cables made at a store, so that should be good.
 
The amp has a headphone jack that works just fine.
 
The amp says when using 2 speakers, only use 4 8 or 16 Ohm speakers. These are 8.
 
No sound at all when set to Phono, FM/AM, nothing.
 
Am I missing something here? What could be wrong?

There's no way to tell unless someone can actually look at the circuit, because for all we know this might be one of those amplifiers that have a separate headphone amp section (which is why it works) that just shares the potentiometer. In which case you're going to have to find schematics on the amp and then have someone in the DIY subforum check if that's the case.
 
It's also possible that the solder on the speaker output plugs might have been damaged, so the next step will be to open it up and check.
