Hello Dmitriy! 17 Mar 01 08:10, Dmitriy Nesmachny -> Eugene Palenock: KA>>> so the good old Soviet KA>>> the phone did not ring when trying to dial KA>>> numbers from a parallel phone! EP>> Two counter zener diodes, 60V each. DN> Can I have a specific diagram? Zener diodes capacitor (it is there initially) | (call) | DN> And one more thing: what about a phone with an electronic call? The same thing, two zener diodes in an open circuit. If there the bell hangs after the bridge - then there is only one zener diode needed. Best regards, Evgeniy.
