rackmonkey said:With those inductance values, it looks like it's probably a communications/speech transformer. Maybe for HAM radio or intercom applications. Have you swept it?

A5509A
A5430
D6403 (also says LE1-M4391)
mjrippe said:Awesome, will be interested to see the A5509A. By the way, if you want my 5508/5509 set just PM me an offer of cash or trade. I don't think I am going to have time to build a preamp with them anytime soon!
BluegrassDan said:These belong to a friend/client who wanted me to test them out. He has more salvaged parts from vintage consoles than anyone I know personally.
EmRR said:Yeah he’s as OCD about it as I was years ago.
BluegrassDan said:Of course, no one on GroupDIY has OCD, right?
