vintage '70s Continental Electronics mic preamp module

Description

Those are likely canister transformers made by Triad for Continental. Seen in "Rock 10" consoles... this casing and pinout is really ideal for that and only that application; it would take some engineering and forethought to modify the connectors for more universal application.
The unit dates to around 1978-1979 ; no telling how much mileage is left in some of those stock capacitors, or if they need replacement.

Thanks for looking!
