I am working on an older home that has an old "Jefferson Transformer" " Heavy Duty 75 Watts" which is used on the old style butler's notification system. The house was built in 1922. I can presume that the transformer has been in place since then.

The primary side is 110v.

The secondary side has three terminals. The transformer has the following embossed markings:
1 - 2 6 volts
2 - 3 14 volts
1 - 3 20 volts

There is an individual wire on terminals 2 & 3. There is a grouping of multiple wires on terminal 1.

I am about to replace the panel box and need to replace the transformer.

Has any one ever worked with such a transformer and enunciator system? Does anyone know where I can obtain a replacement transformer?

Based on the configuration described above, what are the wires going to the terminals?

I've seen remnants of these systems including non-electrical cable and pulley. Never saw one that was functional.

When I want my "butler" I just yell "honey come here!" :D

Anyway, it sounds like an Edwards tri-volt transformer is what you need. Apparently two voltages are being used- 6 and 14 volts. Maybe the doorbell is on it too?

Is the transformer bad? If you cant get the exact one you could substitute three transformers with the 6 volt being the highest wattage as it is probably for the filament heaters in the tubes But Jefferson Electric is still in business making Transformers. They are located in WI. Here's there web site:

Hold on now. Who said anything about tubes? Any of the ones I have seen were simple buzzer/annunciator types. Push a button and along comes Jeeves. If this were original to a house from 1922 I suspect that would be the case. Anything with tubes in those days wouldn't use a remote LV transformer.
