Title: Identifying transformers
Post by: TubeGeek on March 03, 2014, 09:15:34 pm

I have a few old transformers I'd like to know more about.  I have had them for several years on a shelf.  I think I pulled them from an old stromberg carlson or similar kind of amplifier.

I am most interested in the OT with LO-0135 BK074 writing on it as I have a project coming up I could use it with.  I'd like to see if I could come up with the specs or figure out some data on it.

The second transformer looks like it is a Forest Electric transformer.  That is about as far as I have gotten on looking up the info on it.

Have a look and if anyone has any knowledge of these, I'd appreciate any kind of help.
