Seeking Sescom Transformer Specs

Greetings,

Does anyone know the specs on the Sescom MI-22 and have a hookup diagram? Have a pair, but know nothing about them besides the model number. Also trying to figure out if the MI-13 can handle any DC offset.

Thank you,
Ryan
 
Hi,
According to my very old Sescom catalog:
Primary 15K
Secondary 15K/60K
600 ohm power level: -10
magnetic shielding -3odB
1988 price: $36.30
Primary: Pins 2 ,1
Secondary 1: Pins 4,6
Secondary 2: Pins 5,7
For 60K tie 6 to 5, use 4 & 7
For 15k tie 4 to 5, 6 to 7 use 4 & 7
Shield: Pin 8

None of the specs give any information on DC offset, but it's generally not a good practice.
