Posted by Paul Wills on December 19, 2003, 9:57 am, in reply to "Re: Northern Electric Switch/Ringer problem" On the other hand, if you can get your hands on *any* other magneto phone, you can use them as a local intercom circuit. Regards, PDW Link: Telephone Collectors International
It would be ill advised to use that phone on a common battery line as it is currently wired. The 317 were specifically designed for local battery service. Although it can be done, any modifications to make it work on a CB line would diminish it's value as an antique telephone.

: Thanks for your response. My phone seems to be
: the Oak Northern Electric version of the
: Western Electric No. 317 perhaps the
: "B" and the schematic says
: "N1317A, N1317E, N1317F and N1317G tel
: sets" at the bottom of it. My guess it
: is from the late teens or early 20's and it
: has an outside ringer and a crank. No Dial of
: course. Three internal batteries for the
: ringer (currently not set up).
: Someone seems to have connected a wire from
: Battery Terminal E(?) to the last COND. When
: that is removed the receiver sound is fine
: but the phone still doesn't work properly.
: Naturally, I only want to use this as an
: extension and I really don't want to ruin it
: or hurt my phone line. If it can't be done
: then, so be it I'll use it as a decoration,
: but since I do get a dial tone and sound from
: it I tend to think it is not an impossible
: task. I certainly appreciate any help you
: can give and if you know a repairer, I'd be
: glad to hear of him.
: Thanks again

: First you need to clarify what kind of phone
: you have. Sounds like a dial set (not really
: an antique by most standards, but ---) If
: your phone has an internal bell and you
: connected the two wires from the bell
: directly to the incoming phone line, you
: might get just such a problem as described.
: Bells must be isolated from the DC which
: controls dialing and powers the microphone by
: inserting a capacitor in series with the bell
: circuit. That lets the AC of the ringing
: signal pass through to the ringer, but blocks
: the DC which is used by the dial and the
: transmitter (microphone)
:
: Low receiver can be from many problems, the
: first (if this is a phone from the 50's or
: later, is the small Diode or varistor on the
: back of the receiver can be bad (remove). If
: this is an older set with separate ear piece
: (receiver) and transmitter (mike) usually is
: due to improper wiring or in some cases weak
: magnets in the receiver.
: Again, hate to be so non-specific, but not
: knowing what particular phone you are using
: makes the diagnostics difficult.
