Default Help identifying Output transformer

I am selling some parts from a friends estate for his wife.
I have 2 new transformers that only have 24S79 printed in white on them.
One of the boxes has part of the name on the label which is HALLDOR and then the corner of the label is torn off, could have 2 to 4 more letters.
I can't find any other markings on the transformer.
Here is what the instruction paper says
Push pull plates to line or voice coil 75 watts
Primary: 3800/3300 ohms @ 125 madc
For 3800 ohm primary connect plates to brown and blue
For 3300 ohms connect plates to red/grn & red/yel
connect red to B+
Secondary 4/8/250/500 ohms depending on connections
Any help would be appreciated.

Thank you very much for the help. I was beginning to think that no one could figure it out. Someone else told me to come here for the answer.
