Dear Fellow Engineers, I am now 61 years old and trying to relive my boyhood dreams. I am in the process of converting a 1965 red GPO telephone into a 1966 Batphone complete with cake cover! One area yet to be achieved is the ringtone, please see link: https://www.youtube.com/watch?v=4uCr4MD7dTk for the phone ringing sound.
The current bell ringing system is I beleive runs from a 75V ac supply. I am having difficulty finding a buzzer that sounds very like the Batphone. One problem is the inability to hear the buzzer before purchase from the Internet. Do you know if such a buzzer exists?
I also have the exact ringtone on my mobile phone, so is there a component I can connect to the GPO phone that can be loaded with this ringtone and thus duplicates the Batphone ringtone? I know that it may be alot of trial and improvement but do not mind a challenge! Any assistance would be warmly welcomed.
