i do not have a brand name for these, maybe somebody out there has a clue,

these are the last of the mohicians except the foreign stuff,

the 2750 was nothing more than 2 chokes in one can, soldered lams, so a scrap job.

i un did the other two.

A7318 - 5,600T / 260 T = 1:21 Turns ratio as a mic input, 1.25 H pri. L. D-.60, 10 Ohms DCR -pri

C-405: 4,600 T / 326 T = 1:14 as a mic input, # 36 and #44 wire, sq stack F lams,
