Hi yet again!

I have read and learned from the responses and input RE the 107A spokesman speaker. Now here I am with another Q, and that is the 106B speaker. What was the difference between the 107A and the 106B besides the shape? I have seen the 106B with both a green enclosure and installed in a rack mount panel. I am assuming (there I go again) that the 106 had a built in amp.

Was there ever a tube based amp used in a speaker phone speaker or controller?

On a similar topic, I was sorta disappointed when my "Western Electric 666" transmitter arrived. It turned out to be an ITT clone. I will not complain to the folks who sold it to me because they are a very good supplier of things I need, and they practically gave it to me. Mistakes happen, and God only knows that I have made many myself.

Someday, I hope to find a green Weco 666 Transmitter to go with my 760A speaker! I see them about four times a year on e-bay, and next one that comes along, I will pounce on it.

Best,

Joe

The 106 is an amplified speaker, and operates in a similar way to the Spokesman® speaker. It is more rugged and can be powered from more optional sources. It's more of an industrial version, as compared to the lighter-duty 107. They were used widely in central office, FAA and military applications.

They were only made in -51 green, and the front can be removed so that the entire unit can be mounted in a panel. The speaker comes with a paper template that allows the installer to make the big hole and the smaller mounting holes properly.

I have never seen an ITT clone of the 666 transmitter. If you have time, I'd be interested in seeing a photo showing the housing, and what components are inside, and who manufactured them.

Yes, of course, the Bell System used tube-based amplifiers before they invented the transistor. Here is a descriptive BSP about the 100-type tube amplified speaker system.

A pox on you Arthur! I just spent a half hour going through an old RCA tube catalog.

What? You didn't remember the specs on all those tubes?

HI Arthur,

I horribly mis-spoke about the "ITT" transmitter, it is actually a Northern Electric copy of the WECO unit.

I will still be happy to photograph it if you would like and e-mail them to you.

I guess this is a case of an exhausted, stressed out senior moment!

Best,

Joe

That was just a test.

I know that only WE and NE made the 666 and other 3-type speakerphone apparatus.
