CW Sounder 1000 ohm coil voltage?
Hello there,
I'm hoping some of you telegraph key and sounder collectors/operators will
have an answer for me.
I've got a 1000 ohm sounder here that I'd like to operate. Is/was there as
standard/defined voltage or current used by telegraph services for the
various mechanical telegraph sounders, based on their coil resistance?
Thanks for your reply answers.
