How to create an Old Dialtone using Analog Electronics
« on: April 20, 2019, 03:15:29 PM »
Is there any way to recreate an old sounding dialtone using modern off the shelf analog electronics ?

I know you can buy new vaccume tubes made for PreAmps, Is there any way I can combine those to create an Old City Dialtone?

This is back-engineering, The first dial-tones was made bu a hum of the mains frequency, a buzzer, and later some resonant circuit(s).  Different development by different companies, no standards.
