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

Many catalog pages are online at bunkerofdoom.com

It's in the 1939 Hammanual and ctaalog 140H from May 1948. Maybe others.

PP 6L6, 400V plate, -25V bias, 6600 Ohms CT, 30W, 40W max., Pri. DC mA 150, matches to 5000, 7500, and 14500 Ohms, Sec. mA 150.

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
