Anybody know how much a hi fi telefunken stereo and record player set from 1960 is worth

Depends on location, condition, desirability of the model, and what the market for such an item is in your area. The value is what someone wants to pay for it. I can imagine it being worth somewhere between 5$ and 150$, but beyond that you will have to take a guess and try to sell it for what you think you can get for it in the time frame that you want to wait for a buyer.

It's a telefunken hymnus 5014 wk stereo system
