Does anyone know the correct pin out of this Thordarson T45364 modulation transformer?
Or it would help a lot if someone knows what was used in and could send me a copy of the schematic.
 I was told it is rated for 500 watts and out of a military transmitter.

Thanks,
Dan

I found some info online: https://www.lintechcomponents.com/product/002356863/T45364/96256

Unfortunately, I couldn't find info via a Thordarson catalog.

"T" numbered Thords are never listed in catalogs or data sheets. 

They were built to spec for bulk OEM sales.  Sad

Thank you for the link to the mod transformer info. Looks like this transformer is just what I need for my project. I am wanting to build a pair of 813s modulating a single 833A. I have a rack cabinet to build it in that is about the same size as a Globe King 500 except a few inches deeper front to back.

Thanks again,
Dan
