[ARC5] ARC-5 IF transformer IDs

[Ian Wilson]

I've come across a few IF transformers with numbers that don't appear
in the SCR-274 drawings:

    85kc:  9641, 12012
1415kc:  9690
2830kc:  9699

Are these interchangeable with the part IDs quoted in the SCR-274 docs:

    85kc:  4698, 7267, 4677
1415kc:  7274, 7275, 7276
2830kc:  7277, 7278, 7279
