Adding wireless speakers


We recently bought a vintage Grundig Rossini 2 stereo and I am interested in adding accessory wireless speakers to hear the records outside without running new wires. 
I presume I’ll need some sort of Bluetooth transmitter to attach to the existing speaker wires. 
that’s what my logic tells me. 
Any help would be greatly appreciated.

I think this is impractical.  This console is ancient (more than 50 years old) and I cannot find any information on-line about any external connections.  

Here's a thread about a slightly newer model and it makes me even more pessimistic about interfacing with your model. Grundig

If you have decent WiFi, consider an independent, wireless streaming speaker for outside music.
