The OP stated that there is an electrolytic in the circuit in place of the coupling cap and wondered what effect it has. Yadda, yadda, yadda. Don't we see this all the time? Someone grabs whatever cap m they may have and IF it works, fine. So there it sits for 60 years. So now we can put the proper part in and listen on headphones. Easy, peasy.
