I've got some of these:

4 3 2 1
Collins Radio Co.
667-0187-010
JB-7030
JB Electronic Transformers, Inc.
JB Part No. 124A29
8 7 6 5

I think they're input/output dual purpose, b/c there's four of them in something I think was meant to be a preamp, but I don't really know. Anyone have any idea what they're good for?
 
They are from the 212L console, and appear to be the input transformers. They are listed in the manual as 19 ohm primary and 120 ohm secondary. 50 / 150 / 400 ohm input Z, I'd guess the secondary is in the 1200 to 2K ohm range. I have no schematics with my manual.
