That's very cool, but a lot of effort; I just want one of those with a 3.5mm jack plug, so I can do video calls by speaking into a 70 year old bakelite earpiece, haha.
Does anyone know if the electronics in these old phones will allow me to just wire up a 3.5mm cable to the receiver? Or will this need some active amplification?
