Vintage Retro Cassette Players Portable GENERAL Electric PARTS ONLY

Vintage General Electric Cassette Recorder Model 3-5314A - Silver, parts. This tape player was clean in the battery compartment and does sound like it's supposed to be engaging but nothing comes out I am unsure if the volume control is broken or what's going on with it it doesn't appear to have any damage but that's the one I can't get to play so I'm including it for parts
