Ken:
I have "Instruction Book for Radio set SCR-274-N" though it does not
have the AAF TO number 08-10-50 on it. Page # 58 is table 20, list of
replaceable parts (cont.) with at the top parts of dynamotor DM-32-A P.
63 is also part of table 20 with modulator parts.
I can copy these pages, though prefer to postal mail than scan them.
