My Telephone Collection / Connor's Collection

It's only 3 at this point,but considering how quickly that happened I can see this getting out of hand. The green 500 is internally from 1965 but the shell is from "79,presumably when it got modular jacks. It came from a buddy of mine who found it at the dump and it only needed a new set of modular jacks and a earpiece to be fully functional. The blue 2500 was a recent eBay find that only needed a faceplate and a new 72 model keypad. Can't say I'm a fan of the feel of the 72,but at least it works unlike the old 35 model. I've actually got 3 2500 parts phones that all have junk keypads that I need to replace. All the date codes are from around 81 in this one. Then finally we have the 5 line rotary that has a sticker over the model number. It's' 5 lines with a hold and a headset connector in the back. Every date code in this thing is 1977 and based on the condition,I don't think it was ever messed with. It came from an antique store near me,but they didn't know where it was originally used. I have a modular cord wired to line one so it is sort of usable as a normal phone.

A lot of guys are smarter than me figured out that it is an earlier version of the 266-w transmitter which was designed to install in test sets.  The unusual shell design is common to both transmitters. This one has a 6-digit number plate with the usual A.B.T asterisks. These transmitters were mounted inside the box of test sets, perhaps to avoid damage when the test set was knocked around in the field (on the back of the horse cart no doubt).

Auction Talk / Re: ATEA Model 51
« Last post by Jack Ryan on Yesterday at 09:02:26 PM »
AE (pre GTE) had factories in England (ATM),Belgium ATEA, Italy Autelco among others. Those sets have nothing to do with Canada. I once worked on a set with 1944 dates with brown bakelite parts and brown paint. It had the push button on the front

To be fair, they were not just AE factories.

When ATM was set up, AE had an interest in it but it did not own it. It was a company in its own right and developed its own products - often based on AE products but not always. ATM developed the SxS exchange in its own direction. At one point, WE had a license to distribute ATM SxS equipment (but not AE SxS).

ATEA existed before AE had an interest in it and developed its own products. After AE purchased ATEA, ATEA worked with ATM and independently to produce its products.

Autelco was also independent and designed its own products. Some were unique and others similar to AE products. For example, they made a phone that looked like an AE 40 but the insides were totally different.

The group, of course was more than the sum of the members. Each benefited from being part of the group.

I used "AE" to refer to the parent just for convenience.

Diagram Requests / Re: Wiring Diagram for North 7h6 desk set

That is with an AE dial.  I want one for a WE dial, but somebody else told me 7h6 is wired just like a 302, so I can work from there.

The phone posted by tubaman is, as he stated, a Model 51. It was made by ATEA (an AE subsidiary at the time). It is what I would call a PAX version, but others disagree with that. It appears to be original to me except for the handset cord. It was made before the U56 and continued in production in parallel with the U56. The Model 50/51 does not have a handle.

The phone posted by countryman is a Model 50. The original finish has been removed, it has been copper plated, a handle has been added and it has the wrong handset.

The U56 was based on the Model 51 – it has a smaller button, a carry handle and a different handset (similar to the WE F handset). It was made by both ATEA and BTMC – the two versions were virtually identical but had different dials; the ATEA version had a version of the ATEA Type 24 dial and the BTMC version had a version of the BTMC 7000 series dial. The U56 and the Type 50/51 use an almost identical but different dial.

Most of the “Kettle Phones” are modified U56s.

The attached image is of a U56 with the older RTT logo. Later versions had RTT with overlapped letters.

RB - Okay I an not planning on using the 50uf.  I have not been able to find the 250uf.
I got the FIG 6.
The 4 BATT sw wires are Green,  Gray,  OR/Red,  and Red/Green

corrections
GROUND may be found at the "+" point of the 125uf capacitor. in fact, that may be a good place to find and use as reference.
---THE CAPACITOR I FOUND IS 50uf AND ON THE SAME MOUNT AS A RELAY MARKED "NL"---

Don’t use the 50. It is ground on + side, and after the Batt switch.

Also, your schematic, page 2 upper left corner under fig2
Those are all the power etc connections.  --- I AM SORRY TO SAY I CAN'T FIND "FIG2 WHAT SCHEMATIC # ARE YOU LOOKING AT?---

Fig 6

pin 16 is the incoming connection to the BATT sw, the NL relay is after the BATT switch.
I believe it is also RED, it makes sense.---THERE IS NO RED WIRE AT THE BATT SWITCH---

what color are the wires on the BATT sw?

I noticed on one photo that it was marked "Automatic Electrique" did GTE have European offices back then? or were these all made in Canada?
