Pair vintage early '60s TRIAD A-11 audio input transformers

Description

Per the 478- part numbers, these canisters were produced for Gates broadcast amplifiers probably between the late '50s and early 1960s. Commonly deployed in a microphone input-to-grid circuit. Multiple impedance taps plus CT on the primary. in the "J" style shield canister, like most of the Triad audio trannies seen these days.
Good used shape, functional, normal test readings; D
C resistances measure:
across primaries - between several ohms to ~50-54 ohms, depending on taps
at secondaries - 5470 and 5660 ohms
You may not see a pair of these on the market again, so bid early and often!
thank you for looking!
