Anyone have any experience with a Bell Systems 2752 wall panel phone, 1752 or 752? I am working on a 2752 phone that has a bad speaker for speakerphone that has a open circuit. Anyone recall what ohm speaker was used for these speakerphones. Since the bad speaker isn't reading any resistance I can't tell what to replace the speaker with. It's next to impossible to find another 2752 to scavenge from or to check ohms of speaker. I have looked in every old manual that I can get my hands on and can't find specs for the speaker. Any help is greatly appreciated!

Dear D-a-#:
The speakerphone system components that are inside a 2752 tel set are electrically the same as the parts in a stand-alone 3-type system. Those use a 760A speaker. I just pulled one of mine off the shelf and it measures around 28 ohms.
If you have a problem finding a replacement, I might have the guts from a spare 760A I could sell you, but I would first try building out with some resistors and using an 8-ohm speaker. See if that works.

No, I'm not good enough to pull one off YOUR shelf. I pulled one off MY shelf.
You can stay in touch using that old reliable, the PSTN:
