Stancor A-3843.  Could use some basic data.  My Stancor catalog doesn't have it.

Way cool!  Thank you! Thank You!  I'm not good at these searches.  This is perfect for yet another Eico 720 project.

That sounds like fun! pls post pics on it when you get a chance.

Unfortunately, there are so many models of xfmr in the catalogs, it is not time-effective for me to create any kind of model#-searchable index.

There are a few other sites with similar materials. I usually use "old transformer catalog" in altavista.com or google.com
