The A&A1 controllers might show up at Rat Shack, although it's been a long time since they carried them. Best bet is sandman https://www.sandman.com/images/wizscale.jpg for the Wizard's Tool Box relays. Carl This model is end of life

Thanks, Bill (careful -- all the pages are there, but not in order) The ITT501 is a larger system, but a near-clone of the WE501 and the wire designations and the installation style is the same as the 551, so it should provide good guidance. Also, there was a guy who sells A-lead adapters periodically on eBay for $20, listed as "A-Lead Control Unit for Western Electric 1A2 Key System". If you are installing traditional 500-style single line phones, some of them can be rearranged to provide A-lead control from the hookswitch. Depends on the model.

They are not engineered properly, and several people have brought that to his attention. They will not work on pulse phones, as the relay is not slow-release, causing them to chatter (with the resultant lamp flickering) when the rotary phones dial. Arthur P.

Thanks, Bill I can understand the desire to keep some of the manuals quiet but this switch is, conservatively, 20 years old. I don't think it's going to be considered state secrets if someone is crazy enough to look through it. That being said, if you can PM me the link I would like to see it :-) I was familiar with all of the old GTE/Automatic Electric stuff, I didn't grow up in a Bell town.

Ed did have the A lead relay for the 1A2 PM him to see if he still has them. As far as djweis post, it's not the length of time, it's the policy of the board. One point, when a thread keeps coming up with different questions on the same system it does tend to get confussing for those trying to find answers. It's better to start a new topic so others can search the board and find the answers they may need, instead of reading through a thread this size to find their answer. Retired phone dude
